Description

本発明は、次亜塩素酸、又は二酸化塩素を次亜塩素酸塩や亜塩素酸塩の水溶液に塩酸、硫酸、などの無機酸や酢酸、乳酸、クエン酸等の有機酸の水溶液の少なくとも、いずれか一つの酸性水溶液を加えて生成した殺菌水を用い、野菜等の食材の殺菌する工程において、殺菌水を次亜塩素酸などの特徴であるpH6からpH5の間の最も殺菌力が高い領域で使用するのが望ましいが、しかしこのpH領域はpH管理が極めて困難であるとともに、極端に酸性に偏ると塩素ガスの発生もあり危険でもある。そのため、このpH範囲での使用できなかったという次亜塩素酸利用技術の問題点を解決し、ウイルスやO157等の危険な感染型病原体に対する食材の安全を確保し、しかも大量の食材を、短時間に高いレベルの殺菌状態にするために成されたもので、炭酸ガスの添加により、高濃度の次亜塩素酸による殺菌がでも、一般の食材加工現場でも安全に使用できる技術に関するものである。  In the present invention, hypochlorous acid or chlorine dioxide is added to an aqueous solution of hypochlorite or chlorite in an aqueous solution of an inorganic acid such as hydrochloric acid or sulfuric acid, or an organic acid such as acetic acid, lactic acid or citric acid, In the step of sterilizing foodstuffs such as vegetables using sterilized water produced by adding any one acidic aqueous solution, the region having the highest sterilizing power between pH 6 and pH 5, which is a characteristic of hypochlorous acid, etc. However, in this pH range, pH control is extremely difficult, and if it is extremely acidic, chlorine gas is generated, which is dangerous. Therefore, the problem of hypochlorous acid utilization technology that could not be used in this pH range was solved, food safety against viruses and dangerous infectious pathogens such as O157 was ensured, and a large amount of foods could be shortened. It was developed to achieve a high level of sterilization at a time, and it relates to a technology that can be safely used even at general food processing sites, even when sterilized with hypochlorous acid at a high concentration by adding carbon dioxide. .

レタスやキャベツ等の水中に沈む葉物野菜などに適した方法で、水面近傍に維持して搬送しながら、前記殺菌水を水面上方から水面に激しく噴射する噴射洗浄を行いながら同時に次亜塩素酸により殺菌する方法と、キュウリやピーマン等の浮く野菜などに適した方法で、水面から一定の深さの水深を保持して、高濃度の次亜塩素酸、例えば1500ppm、の強力な殺菌力と炭酸ガスの発泡化作用を用いて、浸漬による水圧浸透作用を加えて洗浄と殺菌をおこなう方法において、
被洗浄殺菌物を殺菌水の水面近傍や所定の水深位置に保持しながら搬送させて、洗浄、殺菌をおこなうことによって、発泡化による洗浄作用や、噴射水流の持つ流体的特長と次亜塩素酸のpHを安定させる炭酸ガスによるpH緩衝作用を用いて、洗浄効果と殺菌力を最大限に、活かす、洗浄殺菌技術に関するものでる。
Hypochlorous acid at the same time while performing washing and spraying to spray the sterilized water violently from above the water surface while transporting it while maintaining it near the water surface in a method suitable for leafy vegetables such as lettuce and cabbage. And a method suitable for floating vegetables such as cucumbers and peppers, maintaining a certain depth of water from the surface of the water, and having a high concentration of hypochlorous acid, for example 1500 ppm, In the method of washing and sterilizing by adding the water pressure osmosis effect by immersion using the foaming action of carbon dioxide gas,
By carrying the sterilized material to be cleaned in the vicinity of the surface of the sterilizing water or at a predetermined depth, cleaning and sterilizing can be performed, the cleaning action by foaming, the fluid characteristics of the jet water flow and hypochlorous acid The present invention relates to a cleaning and sterilization technique that maximizes the cleaning effect and the sterilizing power by using a pH buffering action by carbon dioxide gas that stabilizes the pH of the liquid.

又、同時に食材の表面に付着した、小さな虫、髪の毛、ごみなどや、野菜類の表面にある水をはじく皮膜物質中に住み着いた細菌等をより効率良く除去して洗浄をおこなう方法に関するものである。  At the same time, it relates to a method for more efficiently removing small insects, hair, dust, etc. adhering to the surface of foodstuffs, bacteria that settled in the water-repellent film material on the surface of vegetables, etc. is there.

なおかつ炭酸ガスを溶解することで起こる、pH5〜6近辺のpH安定化作用(pH緩衝作用、以下は緩衝作用と言う)を併用することにより、高濃度(3000ppmぐらい)までの次亜塩素酸水溶液を安全に使用できることや、炭酸水の発泡の性質や水面を激しく水で叩く事で大量の泡が生まれる性質を利用し、小さな気泡の生成と消滅から起こる振動攪拌作用、微弱な超音波振動の発生や、大量の泡による物理的な洗浄作用等を利用して、殺菌水が食材の表面に絶え間なく作用し易くし、洗浄と殺菌効率を高めることや殺菌工程後の脱臭を目的とした、洗浄、殺菌、脱臭方法及びその装置に関する。  Moreover, hypochlorite aqueous solution up to a high concentration (about 3000 ppm) by using pH stabilizing action around pH 5-6 (pH buffering action, hereinafter referred to as buffering action) that occurs by dissolving carbon dioxide gas. Can be used safely, and the foaming properties of carbonated water and the property that a large amount of bubbles are created by striking the surface of the water with water, vibration agitating action that occurs from the generation and disappearance of small bubbles, the weak ultrasonic vibration Using the generation and physical cleaning action by a large amount of foam, the sterilization water easily acts on the surface of the food continuously, aiming to improve the cleaning and sterilization efficiency and deodorization after the sterilization process, The present invention relates to a cleaning, sterilization, deodorization method and apparatus.

従来から、次亜塩素酸ナトリウムや亜塩素酸ナトリウムの希釈液を被洗浄殺菌物にシャワー状に墳射して殺菌を行うか、または、浸漬して殺菌することは知られている又、これらの液はアルカリ性で酸化力が弱いため、これらに酸を作用させて、極めて高い酸化力の次亜塩素酸や二酸化塩素を生じさせると殺菌力が増大する事も学問的には知られていた。しかし、前記希釈液に酸を作用させてpH5〜6にすると、塩素ガスや二酸化塩素ガスの発生によって危険であるいう性質があり、高濃度(1000ppm以上)の次亜塩素酸ナトリウム水溶液を酸性のpH5.5にするような量の酸を加える機構をもった洗浄、殺菌機械の商品開発はなされなかった。ほとんどがpH6〜7程度で次亜塩素酸ナトリウム、又は次亜塩素酸濃度が200ppm以下の範囲を利用しようとする目的のものであった。  Conventionally, it has been known to sterilize by diluting sodium hypochlorite or dilute solution of sodium chlorite in a shower-like manner on the sterilized material to be cleaned. It is also known academically that sterilizing power increases when alkaline solution is weak and has low oxidizing power, so that acid acts on them to produce hypochlorous acid and chlorine dioxide with extremely high oxidizing power. . However, when an acid is allowed to act on the diluted solution to pH 5-6, there is a property that it is dangerous due to generation of chlorine gas or chlorine dioxide gas, and a high concentration (1000 ppm or more) aqueous sodium hypochlorite solution is acidic. There was no product development of a cleaning and sterilizing machine with a mechanism for adding an amount of acid to adjust the pH to 5.5. Most of them were intended to utilize a range of pH 6 to 7 and sodium hypochlorite or hypochlorous acid concentration of 200 ppm or less.

これは次亜塩素酸水溶液のpHが4をきると塩素ガスが発生して人体に危険な作業と成るからであり、しかもこのpH領域では少しの量の酸でも、急激にpHが下がり管理が難しく、1000ppm以上もの高濃度になれば成る程、この塩素ガス発生が増大し、危険度も増大するためである。
しかし、次亜塩素酸の殺菌力はpH5.5で最高となる特徴があるため、この領域で使用したいというニーズがあった、しかも悪いことに、有機物と反応して殺菌が進むと塩酸分が生成されて、pHが初期以上にどんどん下がると言う危険な特徴も在ったため、この領域では使わないという背景があった。
This is because when the pH of the hypochlorous acid aqueous solution is less than 4, chlorine gas is generated, which is dangerous to the human body, and even in this pH range, even a small amount of acid suddenly drops the pH and is difficult to manage. This is because the higher the concentration of 1000 ppm or more, the greater the generation of chlorine gas and the greater the risk.
However, since the sterilizing power of hypochlorous acid has the highest characteristic at pH 5.5, there was a need to use in this region, and worse, the reaction with organic substances and the sterilization proceeded, the hydrochloric acid content increased. There was a dangerous feature that it was generated and the pH dropped more than the initial level, so there was a background that it was not used in this region.

又、従来は次亜塩素酸ナトリウム又は亜塩素酸ナトリウムの水溶液を数個の浸漬槽に入れその中に野菜等の食材を浸漬して、水洗浄の槽と殺菌水の槽を直線ライン状に配置してバケット式に食材を移送して殺菌を行う野菜洗浄機に次亜塩素酸ナトリウム200ppmを使い約8分の殺菌工程で処理することが良く知られていたが、細菌類の多様化と10の8乗以上の汚染した野菜の輸入も当たり前になったため、この方式には限界が現れていた。  Also, conventionally, sodium hypochlorite or sodium chlorite aqueous solution is put in several immersion tanks, and vegetables and other ingredients are immersed in it, and the water washing tank and the sterilizing water tank are linearly formed. It was well known to dispose of vegetables in a bucket-type washing machine that uses 200 ppm sodium hypochlorite for a sterilization process for about 8 minutes. The import of contaminated vegetables over 10 to the 8th power became commonplace, so this method had its limits.

又、これらの装置の、殺菌洗浄槽内の下部よりエアーを殺菌水中で噴射して、気泡による攪拌効果を利用した殺菌装置は、多くの商品が市販されているが、野菜などが世界中から輸入されるようになって、新たな問題として、生育地域の気候の違いからくる、表面の生成膜の違いや微生物の多い少ないという違いが、従来技術では極めて短い時間内、例えば30秒内に均一な10の二乗レベルの菌数に野菜を殺菌できないと言う問題が生じていた。
しかも、24時間の生産方式の中で大量の野菜を1分以内で、10の二乗レベルの一般細菌数に安定的に処理したいと言うニーズがある。
In addition, many products are commercially available for sterilizers that use air bubbles in the sterilization water and utilize the agitation effect of bubbles from the lower part of the sterilization washing tank of these devices. As a new problem, the difference in the surface formation film and the difference in the amount of microorganisms in the conventional technology is a very short time, for example, within 30 seconds. There was a problem that vegetables could not be sterilized with a uniform number of 10 squares.
Moreover, there is a need to stably process a large amount of vegetables in a 24-hour production system within a minute to a general bacterial count of 10 squared level.

又、搬送コンベアーなどの上に食材を載せ電動式のコンベアー移動時に上下側方向や左右側方向から激しくシャワー状にオゾン含有水を噴射して食材を殺菌する方法はすでに知られている。しかし、被洗浄殺菌物を水面近傍に保持して水面上方から水面を激しく泡立てるような洗浄と殺菌を同時に行う方が効果的であるが、その方法は本発明者の一人が公開した以下の非特許文献による方法である。
本発明者の一人である岡崎 龍夫が出願した、特願2002−77260号公報に紹介されたものはいくつかの改良すべき点があった。例えば、その発明者は、この時点では、1000ppm以上の高濃度の次亜塩素酸を使用することが非常な危険を伴うと言う考えから、1000ppm以上の高濃度次亜塩素酸を使用する想定は成されなかった。 また、この時点では、炭酸ガス溶解が前記高濃度の次亜塩素酸水溶液でその濃度が1000ppm以上でもpHを安定化する緩衝作用として使えるものであると理解していなかった。単に殺菌水を炭酸水で希釈し、発泡化作用を利用することが主であったが、殺菌工程中に炭酸濃度が減少してしまうため、本発明においては、循環して噴射洗浄する過程で絶えず炭酸ガスを補充する点も含まれている。 またその他にも、本出願に記載した技術が得られていなかった。例えば、所定の水深を維持して殺菌を行う方法も、兼ね備えた野菜洗浄殺菌装置として開示されていなかった。
In addition, a method for sterilizing food materials by placing the food materials on a transport conveyor or the like and spraying ozone-containing water vigorously in a shower-like manner from the up-down direction or the left-right direction when the electric conveyor moves is already known. However, it is more effective to perform cleaning and sterilization simultaneously holding the sterilized material to be cleaned in the vicinity of the water surface and foaming the water surface vigorously from above the water surface, but the method is as follows. It is a method according to patent literature.
What was introduced in Japanese Patent Application No. 2002-77260 filed by Tatsuo Okazaki, one of the present inventors, had several points to be improved. For example, the inventor believes that using a high concentration of hypochlorous acid of 1000 ppm or more is very dangerous at this point, so the assumption of using a high concentration of hypochlorous acid of 1000 ppm or more is It was not made. Further, at this time, it was not understood that carbon dioxide dissolution can be used as a buffer action to stabilize pH even when the concentration of the hypochlorous acid aqueous solution is 1000 ppm or higher. The main purpose is to simply dilute the sterilized water with carbonated water and use the foaming action, but the carbonic acid concentration decreases during the sterilization process. The point of constantly replenishing carbon dioxide is also included. In addition, the technique described in the present application has not been obtained. For example, a method for performing sterilization while maintaining a predetermined water depth has not been disclosed as a vegetable cleaning and sterilization apparatus that combines the methods.

たとえば、特願昭55−73090号広報参照。広報から分かるように従来の殺菌方法はシャワー状の噴射によるもので、次亜塩素酸ナトリウムの希釈水かオゾン水かによる違いだけであった。  See, for example, Japanese Patent Application No. 55-73090. As can be seen from the public relations, the conventional sterilization method is based on shower-like jetting, and the only difference is whether it is diluted with sodium hypochlorite or ozone water.

あるいは、食材を塩素系殺菌水の中で下側より殺菌水の噴射流によって浮沈並びに回転をさせて殺菌洗浄させながら上部にある移送手段によって出口側に所要の殺菌時間をかけながら洗浄殺菌を行うものであった。
例えば、特願平6−164720号広報参照。広報から分かるように従来技術は、殺菌水の単純な水流を利用して、食材に接触させるだけのものであった。
Alternatively, the food material is washed and sterilized while taking the required sterilization time on the outlet side by means of the transfer means at the upper part while being sterilized and washed by floating and rotating by sterilizing water jet flow from the lower side in chlorinated sterilized water It was a thing.
For example, see the Japanese Patent Application No. 6-164720. As can be seen from the public relations, the prior art uses only a simple stream of sterilized water to bring it into contact with food.

あるいは、次亜塩素酸を使用する殺菌工程において重炭酸塩ナトリウム水溶液を混合して緩衝作用を利用する洗浄殺菌装置は知られている。
例えば、特開2002−241209号広報参照。広報から分かるように従来技術は、重炭酸塩ナトリウムと塩酸を絶え間なく、大量に必要とし、しかも、塩化ナトリウムが副生成物として殺菌水中に、高濃度に生成されるため産業用には適さないものであった。
Or the washing | cleaning sterilization apparatus which mixes sodium bicarbonate aqueous solution and utilizes a buffer action in the sterilization process which uses hypochlorous acid is known.
For example, refer to Japanese Patent Application Laid-Open No. 2002-241209. As can be seen from the public relations, the conventional technology requires a large amount of sodium bicarbonate and hydrochloric acid constantly and is not suitable for industrial use because sodium chloride is produced as a by-product at high concentration in sterilized water. It was a thing.

野菜の殺菌には、近年、次亜塩素酸水溶液による殺菌を行う機械が市場に販売されてきた。しかし、次亜塩素酸濃度としては80ppm〜130ppm程度でpH6〜7の範囲が利用されていた。これは次亜塩素酸水溶液のpHが4以下になると塩素ガス化が発生して人体に危険な作業と成るからであり、高濃度になれば成る程、この塩素ガスの発生が増大し、危険度も増大するためである。しかし、次亜塩素酸の殺菌力はpH5.5で最高となる特徴があり、この領域で使用したいというニーズがあったが、悪いことに、殺菌が進むと次亜塩素酸は有機物と反応して塩酸分が生成されて、pHが初期以上にどんどん下がると言う危険な特徴も在って、このpH領域で高濃度例えば1000ppm以上の次亜塩素酸水溶液は怖くて使えないと言う課題があった。  In recent years, machines for sterilization with hypochlorous acid aqueous solution have been sold to the market for sterilization of vegetables. However, the concentration of hypochlorous acid was about 80 ppm to 130 ppm, and a pH range of 6 to 7 was used. This is because when the pH of an aqueous hypochlorous acid solution is 4 or less, chlorine gasification occurs and it becomes a dangerous work for the human body. The higher the concentration, the more chlorine gas is generated and the more dangerous it is. This is because the degree also increases. However, the sterilizing power of hypochlorous acid has the highest characteristic at pH 5.5, and there was a need to use it in this region. However, as sterilization progresses, hypochlorous acid reacts with organic matter. In addition, there is a dangerous feature that the hydrochloric acid content is generated and the pH drops more than the initial value. In this pH range, there is a problem that a hypochlorous acid aqueous solution having a high concentration, for example, 1000 ppm or more is scary and cannot be used. It was.

また、前述のような機械は、一般的に、殺菌水中で被洗浄殺菌物に噴射水流を当てて攪拌作用を利用するか、殺菌洗浄槽の底からエアーを供給して気泡による攪拌効果を利用するものである。また虫取りなどのために、被洗浄殺菌物に直接、殺菌水の噴射水激を当てるだけの装置である。こうしたものは、食材、食器等の表面の極めて薄い臨界膜(被洗浄殺菌物の微細な表面空間に生まれる、動き難い水の層)を部分的に剥離できても、臨海膜を全体的に剥離し、常に新しい殺菌水を均一に食材表面に、有効に接触させて殺菌をおこなうことができないという課題があった。  In addition, the machines as described above generally use a stirring action by applying a jet of water to the sterilized material to be cleaned in sterilized water, or supply air from the bottom of the sterilizing and cleaning tank and use the stirring effect by bubbles. To do. In addition, it is a device that directly impinges the sterilized water spray directly on the sterilized material to be cleaned for insect removal. Even if such a thing can peel the critical film (the layer of water which is hard to move, which is born in the fine surface space of the sterilized material to be cleaned) partially on the surface of food, tableware, etc., the seaside film is peeled as a whole. However, there has been a problem that sterilization cannot always be performed by effectively bringing new sterilized water uniformly into contact with the food material surface.

このため、一般細菌数を10の二乗レベルに下げるには、長い時間が必要であった、長時間殺菌水に浸漬しておくと次亜塩素酸ナトリウムが200ppmでもpH9近くのアルカリ性であるため、食材が痛み、商品性が損なわれた。又、アルカリ性の薬剤は水でなかなか洗い落ちないという欠点があるため、洗浄用の水を大量に消費し、生産性も悪くコスト競争の激しい市場での、これからのカット野菜生産設備としては使用したくないと言う課題があった。  For this reason, it took a long time to lower the number of general bacteria to the square level of 10, and when immersed in sterilized water for a long time, sodium hypochlorite is alkaline at pH 9 near 200 ppm, Ingredients hurt and merchandise was damaged. In addition, since alkaline chemicals have a drawback that they are not easily washed off with water, they will be used as a production facility for cut vegetables in the future, which consumes a large amount of water for washing and has poor productivity and high cost competition. There was a problem that I didn't want to.

又、従来の殺菌方法では、食材の表面に付着した異物、例えば、小さな虫やごみ、そして細かい髪の毛などは殺菌と別に新たな洗浄除去工程が必要であった。  Further, in the conventional sterilization method, foreign substances adhering to the surface of the foodstuff, for example, small insects and dust, and fine hair, etc., require a new washing and removing process separately from sterilization.

その上、殺菌効果においては野菜などの表面に形成された植物の保護層のさまざまな隙間、例えば豆類の溝に入っている細菌などは、今までの殺菌水の攪拌やシャワー状の噴射流だけでは、なかなか取れなかった。このため、初期の細菌数が10の8乗ぐらいあると、10の4乗レベル以下には下がりにくい状況で、 特にキュウリ殺菌は、10の二乗レベルにするのは絶望的であった。 キュウリ等は表面に在るイボイボの穴の中は海綿状の障害物や毛のようなものが生えていて、殺菌水が弾かれてしまい、殺菌が出来ないため、漬物業界などでは洗濯機のような機械に殺菌水とキュウリを入れて、互いにこすり合わせてイボイボを除去しながら殺菌していため、大量に短時間で処理することが出来ないと言う課題があった。  In addition, with regard to the bactericidal effect, various gaps in the protective layer of plants formed on the surface of vegetables, such as bacteria contained in legume grooves, can only be obtained by stirring conventional sterilizing water or shower-like jets. Then it was hard to get it. For this reason, when the initial number of bacteria is about 10 to the 8th power, it is difficult to drop below the 10th power level. In particular, cucumber sterilization was hopeless to the 10th power level. Cucumbers, etc. have spongy obstacles and hairs inside the wart holes on the surface, and the sterilizing water is repelled and cannot be sterilized. In such a machine, sterilizing water and cucumber were put in, and rubbed together to remove warts, so that there was a problem that a large amount of processing could not be performed in a short time.

又、次亜塩素酸ナトリウムは、200ppm以上の濃度になると微妙に塩素臭が残り、強いアルカリ性のためヌルが付着し、加えて、水で除去しにくいため、水洗浄に時間が掛かると言う問題があった、其ればかりか何度も水洗いが必要であるから水不足の現代では大量の水を消費することは環境上適さないという問題もあった。  In addition, sodium hypochlorite has a problem that it takes a long time to wash with water because it has a slight chlorine odor when it reaches a concentration of 200 ppm or more, and it adheres with null due to strong alkalinity. In addition, there is a problem that it is environmentally unsuitable to consume a large amount of water in modern times when water is insufficient because it is necessary to wash the water many times.

本発明はこのような点を考慮してなされたものであり、請求項1記載の次亜塩素酸塩には次亜塩素酸ナトリウム、次亜塩素酸カルシウムを含み、亜塩素酸塩とは市場で安定化二酸化塩素と呼ばれる亜塩素酸ナトリウムを云う。高濃度の次亜塩素酸による殺菌も二酸化塩素(亜塩素酸ナトリウム)を使用して殺菌する場合も共に、pH範囲がpH5〜6の範囲が殺菌力の強いpH範囲で、本発明は安定した殺菌工程が維持できることを目的としてなされた。  The present invention has been made in view of the above points, and the hypochlorite according to claim 1 includes sodium hypochlorite and calcium hypochlorite. This refers to sodium chlorite called stabilized chlorine dioxide. In both cases of sterilization with high concentration of hypochlorous acid and sterilization using chlorine dioxide (sodium chlorite), the pH range of pH 5 to 6 is a strong pH range of sterilization power, and the present invention is stable. The purpose was to maintain a sterilization process.

また、高濃度の次亜塩素酸や二酸化塩素による殺菌を安全に行えるようにpHを安定させて、キュウリなどのように殺菌が難しい野菜類でも、殺菌後のデータとして一般細菌数が10の二乗レベルの値でコンスタントに維持できるようにし、また短時間、例えば、現行では8分かかるが1分以内で大量の野菜を、いためる事なく殺菌処理を行う目的でなされた。  In addition, the pH is stabilized so that sterilization with high-concentration hypochlorous acid or chlorine dioxide can be performed safely, and even for vegetables that are difficult to sterilize such as cucumber, the number of general bacteria is the square of 10 as the data after sterilization. It was made for the purpose of performing constant sterilization without sacrificing a large amount of vegetables in a short time, for example, currently 8 minutes, but within 1 minute.

また、食材表面にできて、なかなか移動しない水溶液の臨界膜(被洗浄殺菌物の微細な表面空間に生まれる、動き難い水の層)を剥離して常に新しい殺菌水が入れ替わり入れ替わり接触するようにするため、水面上方から水面に激しくシャワー状の噴射水流を与えて水面の振動と大量の泡を生成させることで、泡や攪拌作用による様々な洗浄効果を利用して虫や髪の毛も同時に除去し、同時に殺菌効率を高めて殺菌する目的でなされ、しかも炭酸ガスが蒸散する殺菌洗浄工程が行われる空間を外部空間と遮断し、加えて入り口と出口をウオーターカーテンなどで遮断することによりこの空間が炭酸ガスの溶解機構として機能するという一石二鳥の効果を得るようにした。  In addition, the critical film of the aqueous solution that does not move easily on the surface of the food material (a layer of water that is difficult to move, created in the fine surface space of the sterilized material to be cleaned) is peeled off so that new sterilized water is constantly replaced and contacted. Therefore, by giving a shower-like jet water flow violently from above the water surface and generating water surface vibrations and a large amount of bubbles, insects and hair are also removed simultaneously using various cleaning effects by bubbles and stirring action, At the same time, the sterilization efficiency is increased for the purpose of sterilization, and the space where the sterilization washing process in which carbon dioxide gas is evaporated is blocked from the external space. In addition, the entrance and the outlet are blocked by a water curtain or the like. The effect of two birds with one stone to function as a gas dissolution mechanism was obtained.

また、浮きもの野菜、例えばキュウリ、ピーマン、ナスなどの野菜に関してはイボイボやシワの溝等に殺菌水が浸透するように水面近傍ではなく、一定の深さの水深、例えば水面下約30センチ程度に被洗浄殺菌物を維持して、キュウリ、ナス、ピーマン等の被洗浄殺菌物に激しい水流を与えて被洗浄殺菌物の周りの殺菌水が絶えず新しい液に入れ替わるようにして均一な殺菌ができるようにするか、
又は、キュウリ、ナス、ピーマン等の被洗浄殺菌物は水面下で搬送するネットコンベアーを支える、両側のガイドロラーが一定間隔でガタン、ガタンと上下に振動して、被洗浄殺菌物の周りに析出した炭酸ガスの気泡群が剥離される時に殺菌水が剥離した空間に浸透する作用を利用して、洗浄効果を高める方法のどちらかを目的に合わせて選べるようにした。
In addition, floating vegetables such as cucumbers, peppers, eggplants, etc. are not near the surface of the water so that the sterilized water penetrates into the grooves of warts and wrinkles, but at a certain depth, for example, about 30 cm below the surface of the water. The sterilized material to be cleaned can be maintained, and a sterilized water around the sterilized material to be cleaned is constantly replaced with a new liquid by giving a violent water flow to the sterilized material to be cleaned such as cucumber, eggplant, and pepper. Or
Or sterilized items such as cucumbers, eggplants and peppers support the net conveyor that is transported under the surface of the water. The guide rollers on both sides vibrate up and down at regular intervals and deposit around the items to be cleaned. Using the action of penetrating the sterilized water into the separated space when the carbon dioxide gas bubbles are peeled off, one of the methods for enhancing the cleaning effect can be selected according to the purpose.

特に、次亜塩素酸ナトリウムの水溶液はアルカリ性であるが、pH調整により酸性になると酸化力は80倍も向上することが知られていた、しかし、この場合、酸化力が増強されると同時に、酸化反応速度も極めて早くなる。
この時、酸化が起こった表面で、殺菌剤の消失した部位に、H+イオンとCL−イオン及び極めて薄い水の層が出来る、本発明はこの薄い水の層を取り除いて、新しい殺菌材が常に、接触できるようにして、バラツキのない、殺菌力を得ることができる。同時に、小さな虫や髪の毛等の付着物を取り除く洗浄殺菌と、炭酸ガスの溶解によるpH緩衝作用や炭酸ガスとして蒸散する時の発泡作用を利用して、塩素臭の脱臭もでき、高濃度次亜塩素酸、例えば1500ppmのような濃度でも安全な殺菌洗浄方法及び装置を提供することができる。
In particular, an aqueous solution of sodium hypochlorite is alkaline, but it has been known that the oxidizing power is improved by 80 times when it becomes acidic by adjusting the pH. However, in this case, the oxidizing power is enhanced, The oxidation reaction rate is also extremely fast.
At this time, H + ions, CL- ions and a very thin layer of water are formed on the surface where the sterilizing agent has disappeared on the surface where oxidation has occurred. The present invention removes this thin layer of water so that a new sterilizing material is always present. The bactericidal power without variation can be obtained by making contact. At the same time, chlorine odor can be deodorized by using cleaning sterilization to remove deposits such as small insects and hair, pH buffering action by dissolving carbon dioxide gas and foaming action when evaporating as carbon dioxide gas, and high concentration hypochlorous acid. It is possible to provide a safe sterilization method and apparatus even at a concentration of chloric acid, for example, 1500 ppm.

殺菌水中に沈む野菜等の食材の場合は、食材表面に水激による洗浄作用と水中からの攪拌作用を与え、泡による吸着作用を利用し、虫や細かい異物を殺菌液の上澄みと一緒に排水除去できるようにした虫の除去と、常に新しい殺菌水を直接食材表面に激しい洗浄作用と共に接触させて、泡の消滅による超音波発生作用や泡の剥離時の攪拌作用を同時に得られるようにすることにより、被洗浄殺菌物の商品性を最大限に高めることができる。  In the case of foods such as vegetables that sink in sterilized water, the surface of the food is washed by water and stirred from the water, and bubbles are adsorbed to remove insects and fine foreign matter together with the sterilizing liquid supernatant. The removal of insects that can be removed, and fresh sterilized water is always brought into direct contact with the surface of the food, together with a rigorous cleaning action, so that it is possible to obtain the action of ultrasonic generation due to the disappearance of foam and the stirring action at the time of foam peeling. As a result, the merchantability of the sterilized product to be cleaned can be maximized.

更に、炭酸ガスの気泡化の現象により、被洗浄殺菌物の表面に於ける、微細な空間において、極めて細かい、気泡を発生できるようにし、炭酸水の発泡作用と剥離作用を利用するもので、炭酸水を利用して、水激による洗浄作用と水中に攪拌作用を与え、また、この時、発生する泡の、消滅による、超音波発生作用から出る微弱な、超音波振動で、極めて、小さな空間にも、炭酸ガスの気泡化作用を利用できるようにして、洗浄、殺菌、脱臭を、さらに強力にする方法及び装置を提供するものである。  Furthermore, due to the phenomenon of bubbling of carbon dioxide gas, it is possible to generate very fine bubbles in a fine space on the surface of the sterilized object to be cleaned, and utilizing the foaming action and peeling action of carbonated water, Using carbonated water, it gives a washing action by agitation and stirring action in the water, and at this time, it is extremely small due to the weak ultrasonic vibration generated from the ultrasonic generation action due to the disappearance of the generated foam. The present invention also provides a method and an apparatus for making the cleaning, sterilization, and deodorization more powerful by making it possible to utilize the bubbling action of carbon dioxide gas in the space.

これらとは反対に、浮く野菜、例えばキュウリ、ピーマン、ナス等は浮いてしまうためどうしても水面から露出する部分が多く、殺菌効果にバラツキが生まれる。しかも、キュウリのように穴や溝が在りその奥に潜んだ細菌まで殺菌水が届かないと言うような場合に殺菌水が所要の場所まで浸透するために、少し水圧が必要に成る。この場合、搬送コンベアーを逆転して被洗浄殺菌物をコンベアー上の仕切り板により送り込みながらリング状のコンベアーの下側部分で搬送すると、浮く野菜の浮き上がる力はコンベアーで浮かないように抑えられて一定の深さで維持されながら、殺菌水中を移動する。この時、コンベアーと被洗浄殺菌物の下側にガイド板があると確実に順送りできるので、より好ましい。  Counteract those with the float vegetables, for example cucumbers, green peppers, many portion exposed from just water for eggplant or the like floats, variation born in sterilizing effect. In addition, when there is a hole or groove like cucumber and the sterilizing water does not reach the bacteria hidden in the back, the sterilizing water penetrates to the required place, so a little water pressure is required. In this case, if the conveying conveyor is reversed and the sterilized material to be cleaned is conveyed by the lower part of the ring-shaped conveyor while being fed by the partition plate on the conveyor, the lifting force of the floating vegetables is suppressed so that it does not float on the conveyor. While moving at the depth of sterilized water. At this time, it is more preferable that there is a guide plate on the lower side of the conveyor and the sterilized material to be cleaned, because it can be surely fed forward.

この時の被洗浄殺菌物の前記の問題箇所に、殺菌水の浸透が起きる。またキュウリなどの場合では穴の部分に水をはじく性質があるため、この表面部分は短時間で殺菌する必要が在る。これには高濃度の酸化力が必要であり、次亜塩素酸濃度が例えば3000ppm程度が好ましいが、あまり高濃度では経済性がわるいので1500ppm程度でも十分効果が得られる。また静かにコンベアーで搬送させながら表面に発生した炭酸ガスの泡をコンベアーに一定間隔で軽い衝撃振動を与えて泡を剥離させ、この泡の剥離現象により、元々表面に付着していた細かい気泡が除去され、さらに水圧による浸透作用を利用して、短時間で目的の殺菌部位まで殺菌水を浸透できるようにした。  At this time, penetration of sterilizing water occurs in the above-mentioned problem portion of the sterilized product to be cleaned. In the case of cucumber or the like, the surface of the hole needs to be sterilized in a short time because it has the property of repelling water. For this, a high concentration of oxidizing power is required, and a hypochlorous acid concentration of about 3000 ppm, for example, is preferable. However, if the concentration is too high, the economy is poor, and even about 1500 ppm can provide a sufficient effect. In addition, carbon dioxide bubbles generated on the surface are gently conveyed by the conveyor, and the bubbles are peeled off by applying a light impact vibration to the conveyor at regular intervals. Due to this bubble peeling phenomenon, fine bubbles originally attached to the surface are removed. The sterilized water can be permeated to the target sterilized site in a short time using the osmotic action by water pressure.

さらに、食材を殺菌水中あるいは炭酸水中の水面近傍において殺菌あるいは洗浄、脱臭を行う殺菌洗浄槽内の、リング状の搬送コンバーの輪の内側から上方に吹き上げる水流を作るか又は、リング状搬送コンベアーの下側から、上方に吹き上げる水流を作り、排水口部へ泡及び異物を排出できるようにし、殺菌水の循環管路で殺菌洗浄槽内から循環ポンプ吸入取入れ口までの間にヘアキャチャーや細かいメッシュの異物捕捉用網を取り外し自在に取り付、泡などに吸着した虫、その他の異物を捕捉除去するようにした。  Furthermore, in the sterilization and washing tank that sterilizes, cleans, and deodorizes food near the surface of the sterilized water or carbonated water, create a water flow that blows upward from the inside of the ring-shaped conveyor wheel or the ring-shaped conveyor Create a water flow that blows upward from the bottom, and allows bubbles and foreign substances to be discharged to the drainage port, and a hair catcher and fine mesh between the inside of the sterilization washing tank and the circulation pump suction intake through the sterilization water circulation line The foreign matter trapping net was removably attached to catch and remove insects adsorbed on bubbles and other foreign matters.

又、高濃度殺菌水を使用する場合は、殺菌処理工程の後工程においては、脱臭処理が被殺菌洗浄物の商品価値を上げるために重要である。炭酸水を激しくシャワー状に噴射して洗浄することにより、炭酸水の発泡作用とガス化による気化作用で塩素臭などを吹き飛ばして、殺菌水の残留塩素臭を取り除くことができる洗浄、殺菌、脱臭装置を提供できる。  In the case of using high-concentration sterilized water, deodorizing treatment is important in order to increase the commercial value of the object to be sterilized in the subsequent step of the sterilization treatment step. Washing, sterilization, and deodorization that removes residual chlorine odor from sterilized water by blowing out carbonated water in a shower-like manner and blowing away the odor of chlorine by the foaming effect of carbonated water and the vaporization effect of gasification Equipment can be provided.

本装置の1つの機能において説明すると、食品添加として認められた次亜塩素酸ナトリウムの希釈液中にpH緩衝作用として炭酸ガスを溶解させて300ppm以上の炭酸を生成させてpHを下げることができるため、塩酸などの酸を使用せず炭酸ガスだけでpHを調整できるようにする技術を備えている。
なお、溶解した炭酸ガスが蒸散しても液中には、薬液中にあるナトリウムと反応して重炭酸塩を作るため元のアルカリpH値までは戻らず、また、炭酸ガス濃度を高くしても、pH4以下になることは無く、安全性からの利点がある。
Explaining in terms of one function of this apparatus, it is possible to lower the pH by dissolving carbon dioxide in a diluted solution of sodium hypochlorite that has been recognized as a food additive as a pH buffering action to produce 300 ppm or more of carbonic acid. For this reason, a technology is provided that enables the pH to be adjusted only with carbon dioxide gas without using an acid such as hydrochloric acid.
Even if the dissolved carbon dioxide evaporates, the solution does not return to the original alkaline pH value because it reacts with sodium in the chemical solution to produce bicarbonate, and the carbon dioxide concentration is increased. However, it does not become pH 4 or less, and there is an advantage from safety.

しかも、蒸散した炭酸ガスを逃がさない遮断空間を形成して、この遮断空間で細かい噴射ノズルにより作られた微粒子が炭酸ガスを再吸収できるようにしてあるため、炭酸ガスの消費が極めて少ない。また、別に炭酸溶解用のタンク装置を使用せずに、この遮断空間だけで炭酸ガスを溶解させて炭酸含有殺菌水として利用することもできる。
しかも、高濃度の炭酸水が食材表面に当った時に発生する、発泡ガス化作用と無数の泡による発泡洗浄作用を利用し、小さな虫や髪の毛などの、より効果的な吸着除去と泡の消滅による振動や剥離洗浄作用と超音波洗浄作用による、被洗浄殺菌物の臨界膜を形成する水の膜を除去することを兼ね備えた洗浄、殺菌、脱臭方法及び装置を提供するものである。
In addition, a blocking space that does not allow the evaporated carbon dioxide gas to escape is formed so that the fine particles produced by the fine injection nozzle can reabsorb the carbon dioxide gas in the blocking space, so that the consumption of carbon dioxide gas is extremely small. Further, carbon dioxide gas can be dissolved only in this shut-off space and used as carbonic acid-containing sterilized water without using a separate tank device for dissolving carbonic acid.
In addition, by using the foaming gasification action and the foam washing action of countless bubbles that occur when high-concentration carbonated water hits the food surface, more effective adsorption removal and disappearance of bubbles such as small insects and hair The present invention provides a cleaning, sterilization, and deodorizing method and apparatus that can remove the water film that forms the critical film of the sterilized product to be cleaned by vibration and peeling cleaning action and ultrasonic cleaning action.

又、洗浄、脱臭に使用される炭酸水の生成は、タンク内に炭酸ガスを圧力充填して、その炭酸ガスの中にシャワー状に水を噴射して微細な水粒子として炭酸ガスを吸収させるのが望ましいが、殺菌水の生成工程において次亜塩素酸ナトリウム溶液と塩酸溶液と水を使用するため、重炭酸ナトリウムの水溶液をチュウブで送り出す方式のリングポンプなどを利用して定量的に殺菌水の生成過程で添加して、その重炭酸ナトリウムと塩酸と反応させて炭酸を生成させ、高濃度炭酸を生成させる方法も在るが、NaCL(食塩分)が大量に増加するため金属を腐食させたり、味に影響したりするので、この問題に影響を受けない分野にのみ好ましい方法である。この場合は通常の塩酸添加量よりも炭酸生成時に反応して消費される塩酸分だけ多くの塩酸が必要となり実際の生産現場には適さない。  In addition, carbonated water used for cleaning and deodorization is produced by pressure-filling carbon dioxide into the tank, and water is injected into the carbon dioxide as a shower to absorb the carbon dioxide as fine water particles. However, since sodium hypochlorite solution, hydrochloric acid solution, and water are used in the sterilizing water production process, sterilizing water is quantitatively obtained using a ring pump that feeds an aqueous solution of sodium bicarbonate with a tube. There is also a method of adding carbon dioxide to react with sodium bicarbonate and hydrochloric acid to produce carbonic acid to produce high-concentration carbonic acid, but it corrodes metals because NaCL (saline content) increases in large quantities. Or influences the taste, and is the preferred method only for fields that are not affected by this problem. In this case, a larger amount of hydrochloric acid than the amount of normal hydrochloric acid added is required for the amount of hydrochloric acid that reacts and is consumed at the time of carbonic acid production, which is not suitable for an actual production site.

コンベアーなどの搬送機構ではない、被洗浄殺菌物の搬送方法としては、前記被洗浄殺菌素材の下側に、パイプ類や箱状部材を配置して、その水面側に噴射孔を多数設け、こうした噴射孔から殺菌水の噴射水流に載せて搬送する方法もある。この場合は、循環した殺菌水を吹き上げて水流を発生させると同時にエアーも攪拌作用として噴出すようにして攪拌や、水流で洗浄しながら被洗浄殺菌素材を搬送するような機構にしても良い。  As a method of transporting the sterilized material to be cleaned, which is not a transport mechanism such as a conveyor, pipes and box-shaped members are arranged below the material to be cleaned and provided with many injection holes on the water surface side. There is also a method of carrying the sterilizing water from the injection hole on the jet water flow. In this case, a mechanism may be adopted in which the sterilized water that has been circulated is blown up to generate a water flow, and at the same time, air is also blown out as a stirring action so that the sterilized material to be cleaned is conveyed while being washed with a water flow.

また、前記被洗浄殺菌素材を搬送する機構において、前記、水流により水面近傍の位置に保ちながら、搬送するようにした機構を備え、さらに水面近傍に水車式のような軸や羽根部を支え、その軸部から噴射水流を吐出させる回転羽を配置して、回転羽根には、被洗浄殺菌物が傷付かないよう軟質の素材を使用する構造にして被洗浄殺菌物を歯車のように順送りして、殺菌時間にむらが出ないようにして搬送しても良い、また、この場合は前記回転部材を逆転させる事により該回転部材の下側を搬送経路として利用できるため一定の水深で殺菌洗浄を行う浮き物野菜にも適している。  Further, in the mechanism for transporting the sterilized material to be cleaned, the mechanism includes a mechanism for transporting while maintaining the position in the vicinity of the water surface by the water flow, and further supports a shaft or blade portion like a water wheel near the water surface, Rotating blades that discharge the jet water flow from the shaft are arranged, and the rotating blades are made of a soft material so that the sterilized material to be cleaned is not damaged. In this case, since the lower side of the rotating member can be used as a conveying path by reversing the rotating member, the sterilizing and cleaning can be performed at a certain depth. Suitable for floating vegetables.

本発明は近年、市場において野菜などの食材その他、食器や搬送用ケース類などの殺菌は、極めて高い殺菌精度が要求されるようになってきた。しかし、これと相反して、汚染状態が悪化した食材が輸入されるようになっている。本方法及び装置は、これらの相反する問題を解決することができる。
特に野菜類などにおいて、中国はもとより、メキシコからも輸入されており、気候環境、衛生環境の違いは、野菜類の表面に形成される植物の分泌物や虫の量や異物の硬さ、溶けにくさ、などを異にしている。このため、従来の方法のように、殺菌槽に一定量の野菜を入れ下部からのエアーによる攪拌程度では、対応できなくなってきた。
In recent years, the present invention has come to require extremely high sterilization accuracy in sterilization of foodstuffs such as vegetables, tableware, and transport cases in the market. However, contrary to this, foods with deteriorated contamination are being imported. The method and apparatus can solve these conflicting problems.
In particular, vegetables are imported not only from China but also from Mexico. Differences in climate and hygiene are due to the amount of plant secretions and insects formed on the surface of vegetables, the hardness of foreign matter, and melting. The difficulty is different. For this reason, as in the conventional method, it is impossible to cope with a certain amount of vegetables in the sterilization tank and stirring with air from below.

又、食材の周りから激しく噴射水をかけて、虫取りを行う方法も殺菌水で行えば殺菌も同時に行えるが、この方法も、影の部分ができるため、殺菌効果に位置的バラツキが生じ、近未来の殺菌方法として様々な高度な市場要望に対応できない、又現在多くの殺菌作業の現場で使用されている殺菌作業基準は次亜塩素酸ナトリウムによる殺菌で在り、この点でも殺菌が目的の効果が得られなくなってきている。しかし、本発明によりその全てが解決する。  In addition, spraying water violently from around the foodstuffs, insects can be sterilized at the same time if sterilizing water is used, but this method also creates a shadow part, resulting in positional variation in the sterilization effect, As a sterilization method of the near future, it cannot respond to various advanced market demands, and the sterilization work standard currently used in many sterilization work sites is sterilization with sodium hypochlorite. The effect is no longer obtained. However, this is all solved by the present invention.

又、コンビニエンスストアーの普及により、24時間食品を供給する社会になったが、コスト競争はますます激しく、できるだけ夜中の生産は避け、しかも競争に打ち勝つ新鮮さを維持したい状況にある。又、食中毒は、なんとしても防がなければ成らない状況にある。そのためには、指標として、どうしても、一般菌数で衛生管理をしなければならないため、一般細菌数を常に10の二乗レベルに下げるように管理する必要がある。  Also, with the spread of convenience stores, it has become a society that supplies food 24 hours a day, but cost competition is increasingly fierce, and we want to avoid production at midnight as much as possible and maintain freshness to overcome the competition. In addition, food poisoning is in a situation that must be prevented. For this purpose, as an index, hygiene management must be performed with the number of general bacteria, and therefore it is necessary to manage so that the number of general bacteria is always reduced to the square level of 10.

例えば、野菜などは、出荷時の一般菌数を10の二乗レベルに安定して押えることができれば画期的な衛生管理となる。菌数は倍、倍に増えるため、2次曲線のY軸値がゼロに近い所では、長くX軸から離れないように、初期値が少なければ、少ないほど、野菜の新鮮さは長く保持される。しかも、大量に処理をしてコストを下げる必要がある。しかし、従来はこれらを、同時に達成する、高度な処理技術がなかった。  For example, for vegetables and the like, if the number of general bacteria at the time of shipment can be stably suppressed to the square level of 10, it becomes epoch-making hygiene management. Since the number of bacteria increases twice or twice, the smaller the initial value, the longer the freshness of the vegetable is preserved, so that the Y-axis value of the quadratic curve is close to zero, so as not to leave the X-axis long. The Moreover, it is necessary to process a large amount and reduce the cost. Conventionally, however, there has been no advanced processing technology that achieves these simultaneously.

葉物野菜のように水に沈む野菜においては水面近傍に食材を位置させて、激しく水激を与えることにより、水面に多量の気泡郡が生成され、この気泡に虫を吸着させて、容易に取り除くことが出来る。又、気泡が消滅する時や被洗浄殺菌物から剥離する時に微弱な超音波や浸透作用が発生し、これが、洗浄物の表面の、微細空間にできる水の臨界膜を物理的に破壊して、極めて高いレベルの殺菌及び洗浄力を、作り出す、こうした複合作用により、これまでの問題が解決する。また、浮く野菜においては殺菌水中に一定深さに沈めながら殺菌するため、両者の殺菌上の問題も1台の装置で解消されて、市場に、より安く、より新鮮な食材が、流通できる。  For vegetables that are submerged in water, such as leafy vegetables, foodstuffs are placed near the water surface, and intensely violently stimulated to produce a large number of bubble counties on the water surface. It can be removed. Also, when the bubbles disappear or when they are peeled off from the sterilized material to be cleaned, weak ultrasonic waves and permeation action occur, which physically destroys the critical film of water that can be formed in the fine space on the surface of the cleaned material. This combined action, which creates a very high level of sterilization and cleaning power, solves previous problems. In addition, since floating vegetables are sterilized while submerged in sterilized water to a certain depth, both sterilization problems can be solved with a single device, and cheaper and fresher ingredients can be distributed to the market.

また、高速な殺菌と大量の処理は、従来の次亜塩素酸ナトリウム使用の殺菌方法では不可能で、現在多く市場で利用されている130ppm程度ではなく、高濃度、例えば1500ppm程度の次亜塩素酸を利用できればこの問題が解決する。次亜塩素酸はpH5から6の範囲での管理が難しく少しの塩酸量でもpH3まで急激に下がり塩素ガスの発生が激しく起こり、作業者に危険で使用が出来なかった。  Moreover, high-speed sterilization and a large amount of treatment are impossible with the conventional sterilization method using sodium hypochlorite, and it is not about 130 ppm currently used in many markets, but high concentration, for example, about 1500 ppm hypochlorite. If an acid is available, this problem is solved. Hypochlorous acid was difficult to control in the pH range of 5 to 6, and even a small amount of hydrochloric acid suddenly decreased to pH 3, and generation of chlorine gas occurred violently.

これが炭酸ガスを高濃度に溶解させる安価な方法と装置が開発できたため、水素イオン濃度が高い次亜塩素酸水溶液のpH緩衝作用が得られ、これらの利用が可能に成り、大量の野菜を極めて短時間で高いレベルの殺菌ができるようになった。例えば、市場にある機械で8分程、時間を要した殺菌処理時間が、本発明では30秒で十分可能になり、しかも、最も難しいキュウリに於いても一般細菌数が10の二乗レベルに常に維持されるという結果をえている。  This has made it possible to develop an inexpensive method and apparatus for dissolving carbon dioxide at a high concentration, so that a pH buffering action of a hypochlorous acid aqueous solution having a high hydrogen ion concentration can be obtained, making it possible to use a large amount of vegetables. High levels of sterilization can be achieved in a short time. For example, a sterilization processing time that takes about 8 minutes with a machine on the market can be sufficiently 30 seconds in the present invention, and the number of general bacteria is always at a square level of 10 even in the most difficult cucumber. The result is maintained.

又、今まで炭酸水の発泡作用を利用して洗浄、脱臭をおこなう技術は、食材関係に全く利用されていなかった。これは、炭酸水を殺菌水と共に、連続的に濃度維持が可能な循環式で生成する方法が開発されていなかったからである。塩素臭の除去などは、炭酸水のほうが効果的で、さらにカット野菜では、植物特有の炭酸ガスを液中から吸収する性質があり、野菜の鮮度を上げる効果が在る。
食品の味、香り共に、壊さないため、炭酸水を使用するべきであるが、従来はオゾンを利用して、脱臭をおこなうことが、行なわれている。しかし、オゾンは作業者の多くに頭痛をもたらし、健康に有害である。こうした脱臭にも炭酸水の持つ発泡作用が、食品製造産業の問題を広範囲に解決する。
Moreover, until now, the technique of performing cleaning and deodorization using the foaming action of carbonated water has not been used at all for foodstuffs. This is because a method for producing carbonated water and a sterilizing water in a circulating manner capable of continuously maintaining the concentration has not been developed. For removing chlorine odor, carbonated water is more effective, and cut vegetables have the property of absorbing plant-specific carbon dioxide gas from the liquid, and have the effect of increasing the freshness of the vegetables.
Carbonated water should be used in order not to break both the taste and scent of food. Conventionally, deodorization has been performed using ozone. However, ozone causes headaches for many workers and is harmful to health. The foaming action of carbonated water for such deodorization solves a wide range of problems in the food manufacturing industry.

これらの全てが一体的に解決できるよう本装置は、単に次亜塩素酸ナトリウム水溶液だけに炭酸ガスを溶解させて、pHの5〜6の間酸性に保ち、炭酸ガスだけによる安全な次亜塩素酸含有殺菌水を生成できる方法及び機構でもあるため、洗浄、殺菌、脱臭方法及び、本発明による殺菌装置は、食品業界はもとより、医療や清掃業界の洗浄、殺菌、脱臭に役立つものである。  In order to solve all of these problems, this device simply dissolves carbon dioxide in an aqueous sodium hypochlorite solution and keeps it acidic for 5 to 6 pH. Since it is also a method and mechanism capable of generating acid-containing sterilized water, the cleaning, sterilizing and deodorizing method and the sterilizing apparatus according to the present invention are useful for cleaning, sterilizing and deodorizing not only in the food industry but also in the medical and cleaning industries.

以下、図面を参照して本発明の実施の形態について説明する。図1乃至図25は本発明による洗浄、殺菌、脱臭方法の実施例の全体及びその一部を示す図である。  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 to FIG. 25 are views showing the whole and a part of an embodiment of the cleaning, sterilizing and deodorizing method according to the present invention.

図1は本発明の代表的な実施例の一つを示す。
殺菌水の水面近傍で殺菌処理をおこなうことを特徴とする水激攪拌洗浄殺菌装置1は、食材の投入口2より、例えば、野菜などでは、表面にできるだけ、隠れた部分がないようにしてから投入し、食材は樹脂製のネットコンベアー17の上で、殺菌水面15のところで、食材が沈むか沈まないかの位置に保持されながら、上部空間側から、さまざまな角度を有する噴射ノズル部14から、激しく噴射される殺菌水の中を、所定の速度で図1の右側から左側へ、搬送流下流側に送られていく。
尚、食材の入り口と出口にはウオーターカーテンが配置されているため、蒸散した炭酸ガスが外部に逃げないように成っている。
この時、噴射ノズル部14により洗浄殺菌が行われる密閉空間Cが炭酸ガスの蒸散により、高濃度に炭酸ガスが充満した空間となり、この空間に細かい粒子の噴射を行うと炭酸ガスが再吸収されて炭酸ガスの循環利用が殺菌洗浄と同時に行えるようになっている。
FIG. 1 shows one exemplary embodiment of the present invention.
The water agitation washing sterilization apparatus 1 characterized by performing sterilization treatment in the vicinity of the surface of the sterilizing water is made such that, for example, vegetables are not hidden as much as possible on the surface from the food inlet 2. The food material is placed on the resin net conveyor 17 on the sterilizing water surface 15 while being held at the position where the food material sinks or does not sink, from the upper space side, from the injection nozzle section 14 having various angles. The sterilized water that is vigorously jetted is sent from the right side to the left side in FIG.
In addition, since the water curtain is arrange | positioned at the entrance and exit of a foodstuff, it has comprised so that the evaporated carbon dioxide gas may not escape outside.
At this time, the sealed space C in which cleaning and sterilization is performed by the injection nozzle unit 14 becomes a space filled with carbon dioxide at a high concentration due to the evaporation of carbon dioxide, and when fine particles are injected into this space, the carbon dioxide is reabsorbed. Carbon dioxide can be circulated simultaneously with sterilization and cleaning.

供給管10から殺菌水が電働バルブ9を介して炭酸ガス充填タンクに送られ炭酸ガスを添加しながら、噴射ノズル部14への配管8および下部にある噴射管16と18に供給される。噴射ノズル部14など複数のノズルから噴射した殺菌水で水面15と被洗浄殺菌物7を共に激し水激で叩くようにして洗浄し、同時に殺菌水が良く被洗浄殺菌物7の全部分にからまるようにする。
空間Cは前後がウオーターカーテン5により外部空間と遮断されているため、この噴射により液面上部の密閉空間Cに蒸散した炭酸ガスが徐々に高濃度に成って行く。
この時、空間Cには上部に空気が溜まるため初期に上部から空気を排出できるように一定時間だけ、電磁弁などで上部から外部への連通空間を、開放しておくのが良い。
The sterilizing water is sent from the supply pipe 10 to the carbon dioxide filling tank through the electric valve 9 and supplied to the pipe 8 to the injection nozzle section 14 and the injection pipes 16 and 18 at the lower part while adding carbon dioxide. The water surface 15 and the sterilized material 7 to be cleaned are both washed with sterilized water sprayed from a plurality of nozzles such as the spray nozzle unit 14, and the sterilized water is well applied to the entire portion of the sterilized material 7 to be cleaned. Make it tangled.
Since the space C is separated from the outer space by the water curtain 5 at the front and rear, the carbon dioxide gas evaporated to the sealed space C above the liquid surface gradually increases in concentration due to this injection.
At this time, since air accumulates in the upper part of the space C, it is preferable to open the communication space from the upper part to the outside with a solenoid valve or the like for a certain period of time so that air can be discharged from the upper part in the initial stage.

この時、発生した気泡24は図3(図3は図1の水面近傍を拡大したものである)に記載したように剥離された虫や異物をくるみ、下からの水流27例えば、噴射管16からの水流及び/又は、空気供給管(図示せず)からの空気流によって中央部から両側の排水用トレイ41(図2に図示)に吸収され、アジャスター59を通って排出される。この時、図示はしないが、リング状のネットコンベアー17の内側位置にバブリング用の空気排出管を設けて気泡の上昇による攪拌効果を利用するように成っている。  At this time, the generated bubbles 24 wrap the peeled insects and foreign matter as described in FIG. 3 (FIG. 3 is an enlarged view of the vicinity of the water surface in FIG. 1), and the water flow 27 from below, for example, the injection pipe 16 Is absorbed by the drainage trays 41 (shown in FIG. 2) on both sides from the central portion and discharged through the adjuster 59 by the water flow from the air and / or the air flow from the air supply pipe (not shown). At this time, although not shown, an air discharge pipe for bubbling is provided at an inner position of the ring-shaped net conveyor 17 so as to utilize the stirring effect due to the rising of bubbles.

又、噴射された殺菌水はタンク28に溜り、下側からポンプ11により吸引され、炭酸ガス充填タンクにて炭酸ガスを再度添加した後、再び噴射ノズル部14と殺菌タンク28のネットコンベアー17の下側から上昇流として被洗浄殺菌物7に向かって噴射する噴射管16および18に加圧給水する。ポンプ11,の給水側に、フィルター35がそれぞれ装着されている。また、ノズル部14への加圧給水は炭酸ガス充填タンクを介さずにポンプ11から直接行われても良い。  The sprayed sterilizing water is stored in the tank 28 and sucked by the pump 11 from the lower side. After the carbon dioxide gas is added again in the carbon dioxide filling tank, the spray nozzle 14 and the net conveyor 17 of the sterilization tank 28 again. Pressurized water is supplied to the injection pipes 16 and 18 that inject from the lower side as an upward flow toward the object 7 to be cleaned. Filters 35 are respectively mounted on the water supply side of the pump 11. Moreover, the pressurized water supply to the nozzle part 14 may be performed directly from the pump 11 without going through the carbon dioxide gas filling tank.

この時、ネットコンベアー17は、殺菌水の上面より高い位置に被洗浄殺菌物7が来るような高さとし、単に水激洗浄と殺菌を行う場合、又は被洗浄殺菌物7の大きさが異なるため水面近傍の位置を調整する必要がある場合は、殺菌水面15の高さ調整は、排水トレイ41を上下させることによって行われる。また、この部分にヘアーキャッチャーを装備しても良い、この上下作動はアジャスター59の中でOリングにより、液密におこなえるようになっている。
図2のA−A矢視図はノズル部14や噴射管16および18から噴射される殺菌水の対流により捕捉アミ42での重いゴミの捕捉と虫や髪の毛などの軽いごみが気泡に付着して排水トレイ41より排水除去される流れを示す図である。
At this time, the net conveyor 17 has a height such that the sterilized material 7 to be cleaned comes to a position higher than the upper surface of the sterilized water. When it is necessary to adjust the position in the vicinity of the water surface, the height of the sterilizing water surface 15 is adjusted by moving the drain tray 41 up and down. In addition, a hair catcher may be equipped in this portion, and this up / down operation can be performed in a liquid-tight manner by an O-ring in the adjuster 59.
2 is a view taken along the line AA of FIG. 2 because of the convection of sterilizing water sprayed from the nozzle section 14 and the spray pipes 16 and 18, heavy dust is trapped in the trapping net 42 and light dust such as insects and hair adheres to the bubbles. FIG. 4 is a diagram showing a flow of drainage removal from the drain tray 41.

又、図3は、ネットコンベアー17の上下可動帯の間に回転式羽根21を設置し、その回転により、下側から点線矢印27のように吹き上がってくる殺菌水流を、より加速して、ネットコンベアー17を通して被洗浄殺菌物7に当て、非洗浄物7を裏返にしたりもする説明図である。この場合、回転方向は一定方向だけではなく任意に選択できるようにすることが好ましい。又、U字状の突起物である支え具23はネットコンベアー17上にくし状に複数配列され被洗浄殺菌物7が水流によってからまないようにする順送り用の支え具である。図2にも示すように、支え具23はくし状に配列されている。これらの、ネットコンベアー17や、くし状の順送り用の支え具23は樹脂製か又は、耐薬品性のフッソゴム等のように次亜塩素酸に耐える素材が好ましい。  In addition, FIG. 3 shows that the rotary vane 21 is installed between the upper and lower movable bands of the net conveyor 17, and the rotation further accelerates the sterilizing water flow that blows up from the lower side as indicated by the dotted arrow 27, It is explanatory drawing which also makes the non-cleaning thing 7 turn inside out by hitting the to-be-cleaned thing 7 through the net conveyor 17. In this case, it is preferable that the rotation direction can be arbitrarily selected as well as a fixed direction. Further, the support 23 which is a U-shaped projection is a support for progressive feeding which is arranged in a plurality of combs on the net conveyor 17 so that the sterilized product 7 to be cleaned is not entangled by the water flow. As shown in FIG. 2, the support members 23 are arranged in a comb shape. The net conveyor 17 and the comb-like support 23 for progressive feeding are preferably made of a resin or a material resistant to hypochlorous acid such as a chemical-resistant fluoro rubber.

また、くし状の順送り用の支え具23の代わりに、ネットコンベアー17上にネットコンベアー17と直角に交差する形で30mm程度の高さに樹脂リブを設け、これに例えば、軟質の塩化ビニール材やポリエチレンなどの耐薬品性の強い樹脂材を取り付けて、柔らかく被洗浄殺菌物を順送りする区分け壁として用いるようになっていると、前記くし状の順送り用の支え具23より安くて好ましい。
また、被洗浄殺菌物7は洗浄、殺菌後、渡し用コンベアー36によって、脱臭処理工程に移動される。温度の低いチラー水を高濃度炭酸水するのが好ましい。この時、渡し板37は、くし状になっていて支え具23が被洗浄殺菌物7を渡し用コンベアー36に渡し易くなっている。
Further, instead of the comb-like support 23 for progressive feeding, a resin rib is provided on the net conveyor 17 at a height of about 30 mm so as to intersect the net conveyor 17 at a right angle. It is preferable to attach a resin material having high chemical resistance such as polyethylene or polyethylene and use it as a dividing wall for feeding the soft sterilized material in a soft manner, because it is cheaper than the comb-like support 23 for progressive feed.
Further, the sterilized product 7 to be cleaned is moved to the deodorizing process by the transfer conveyor 36 after being cleaned and sterilized. It is preferable that chiller water having a low temperature is carbonated with high concentration. At this time, the transfer plate 37 has a comb shape so that the support 23 can easily pass the sterilized material 7 to be transferred to the transfer conveyor 36.

渡し用コンベアーから送られた食材は炭酸水が、上側のさまざまな角度から噴射される、炭酸用ネットコンベアー39の上で前記殺菌処理と同じく800ppm程度の炭酸水の水面近傍において発泡作用や水激作用と攪拌振動作用、超音波洗浄作用により、塩素系の殺菌処理による塩素臭を、発散させて匂いのない製品を得るものである。この時、炭酸水の濃度は温度により炭酸ガスの発泡率が異なるが、一般的には洗浄殺菌に使用される水温は約10℃程度のため炭酸濃度は500ppm程度でも十分脱臭効果がある。  Ingredients sent from the delivery conveyor are carbonated water sprayed from various angles on the upper side, and on the carbonated net conveyor 39, the foaming action and water intensities near the surface of the carbonated water of about 800 ppm as in the sterilization treatment. By the action, the stirring vibration action and the ultrasonic cleaning action, the chlorine odor generated by the chlorine-based sterilization treatment is diffused to obtain a product having no odor. At this time, the concentration of carbonated water varies depending on the temperature, but the foaming rate of carbon dioxide gas varies. However, since the temperature of water used for cleaning and sterilization is generally about 10 ° C., the carbon dioxide concentration is sufficiently deodorizing even if the carbonate concentration is about 500 ppm.

図1において、ネットコンベアー17と渡し用コンベアー36によって、被洗浄殺菌素材を次工程に搬送するようになっているが、1つのコンベアーの一部が折れ曲がるようにして、被洗浄殺菌素材を水面下の位置から洗浄殺菌工程外に取り出すようにしても良い、また、洗浄殺菌工程が1000ppm以上の次亜塩素酸水溶液を使用する場合は次工程で炭酸水による脱臭洗浄工程が必要で在り、ネットコンベアー17の材質は特にSUS316材より耐蝕性が優れた、食塩入り高濃度次亜塩素酸ナトリウムや次亜塩素酸に、耐える樹脂製または樹脂製被服のものが好ましい。  In FIG. 1, the sterilized material to be cleaned is transported to the next process by the net conveyor 17 and the transfer conveyor 36. However, the sterilized material to be cleaned is It may be taken out from the position of the cleaning and sterilization process, and when the cleaning and sterilization process uses a hypochlorous acid aqueous solution of 1000 ppm or more, a deodorizing cleaning process with carbonated water is necessary in the next process, and the net conveyor In particular, the material 17 is preferably made of a resin or a resin garment, which has higher corrosion resistance than SUS316 material and can withstand high concentration sodium hypochlorite and hypochlorous acid containing salt.

図3にはネットコンベアー17の一例として図1のネットコンベアー17の一部を拡大して図示をしたもので、被洗浄殺菌物をムラなく搬送するための請求項21及び22に記したに分割壁部材として役立つ支え具23がコンベアー上にコンベアーベルトと直角に設けられている。図示したものは、樹脂棒材をU字形状に曲げたものがたくさん櫛状に直立してコンベアーベルトと一体的に装着してあるが、これに限らず、一定の高さで硬い樹脂製の板でも良く、これに軟質の樹脂板を固定して高さを補う形式のものでも良い。  FIG. 3 is an enlarged view of a part of the net conveyor 17 shown in FIG. 1 as an example of the net conveyor 17, and is divided into the parts described in claims 21 and 22 for transporting the sterilized material to be cleaned evenly. A support 23 serving as a wall member is provided on the conveyor at right angles to the conveyor belt. The one shown in the figure is that a lot of resin bars bent into a U shape are upright in a comb shape and are integrated with the conveyor belt, but not limited to this, it is made of a hard resin at a certain height. It may be a plate, or a type in which a soft resin plate is fixed thereto to compensate for the height.

次に図2について説明する。これは水激攪拌洗浄殺菌装置1のA−A断面図である。殺菌タンク28の底部中央部よりポンプ11によって殺菌水が吸引されフィルター43によって濾過され、再び噴射管16から上方向に向かって上昇流として加圧送水される。又、ネットコンベアー上側の空間から、激しい噴射水激を受け泡だった流れは、両サイドの排水用トレイ41から外部に排水される。この状態で重いものは対流に乗って回動しながら捕捉アミ42に溜り、水流は捕捉アミ42の下側から再びポンプ11に吸引される。  Next, FIG. 2 will be described. This is an AA cross-sectional view of the water agitation washing sterilization apparatus 1. The sterilizing water is sucked by the pump 11 from the center of the bottom of the sterilizing tank 28, filtered by the filter 43, and again pressurized and fed as an upward flow from the injection pipe 16 upward. Moreover, the flow which was foamed from the space on the upper side of the net conveyor is discharged from the drain trays 41 on both sides to the outside. In this state, a heavy object is accumulated in the catching abutment 42 while rotating on the convection, and the water flow is again sucked into the pump 11 from the lower side of the catching catch 42.

また図1において炭酸タンク34および殺菌水タンク28からポンプ29及び11によって吸引しフィルター13及び35により濾過され、それぞれ炭酸水生成タンク30に送られる。ここは、上部から例えば2kg/cm2の高圧炭酸ガスが供給され、水位計や電気制御と、水位保持機構により炭酸水生成タンク30内が一定の圧力と水位に保たれるようになっている。又、炭酸ガス空間が大気圧以下に下がらないように保たれるよう減圧弁、直動式リリーフバルブ等の圧力制御弁31によって保たれている。  Further, in FIG. 1, the water is sucked from the carbonic acid tank 34 and the sterilizing water tank 28 by the pumps 29 and 11, filtered by the filters 13 and 35, and sent to the carbonic acid water generation tank 30. Here, a high pressure carbon dioxide gas of, for example, 2 kg / cm 2 is supplied from above, and the inside of the carbonated water generation tank 30 is maintained at a constant pressure and water level by a water level meter, electrical control, and a water level holding mechanism. The carbon dioxide space is maintained by a pressure control valve 31 such as a pressure reducing valve or a direct acting relief valve so that the carbon dioxide space does not drop below atmospheric pressure.

図4は請求項23に記載した装置の実施例である。
大型のバケットコンベアー50による洗浄、殺菌、脱臭装置である。バケット52が個々のバケットに、大量の食材を上部で通常の搬送コンベアー51から受け入れ、下側に回動して、各バケットが殺菌水の水面53近傍に食材が位置するように、搬送されている。戻り用の戻り管64を介して循環ポンプ(図示せず)から供給された殺菌水の強力な噴出水流54により攪拌洗浄しながら下側から食材に吹き上げる、この時同時に、エアーをタンク62の底側から噴射しても良い。又、上部からは、激しい噴射水激55により攪拌振動及び発泡作用により汚れを除去する。
FIG. 4 shows an embodiment of the device according to claim 23.
This is a cleaning, sterilizing and deodorizing device using a large bucket conveyor 50. The bucket 52 receives a large amount of food from the normal transport conveyor 51 at the upper part and is rotated downward so that each bucket is transported so that the food is located near the water surface 53 of the sterilizing water. Yes. The air is blown up from the lower side to the food while stirring and washing with a powerful jet water stream 54 supplied from a circulation pump (not shown) through a return pipe 64 for return. At the same time, air is blown to the bottom of the tank 62. You may inject from the side. Further, from the upper part, dirt is removed by vigorous jet water 55 by stirring vibration and foaming action.

この時、食材がバケットから飛び出さないように、図7のようにカバーがかぶさるようになっている。これによって食材のバケットからのこぼれ防止ができ、大量の噴射水流によっても食材がこぼれないようになっている。又、A−A区間でバケット58の底部ネットは食材を受け入れやすいように、カバーが両端で立ち上がり図8のようになっている。このような機構を用いると、短時間で大量の洗浄、殺菌、脱臭処理を可能にするものである。このときの、上方からの、噴射水激はその量も多く水流の太さも大きく、この上方からの水流にエアーを混入させて噴射水激を与えると、さらに強力な洗浄が可能になる。At this time, the cover is covered as shown in FIG. 7 so that the food does not jump out of the bucket. This prevents spillage from the bucket of food, and prevents the food from spilling even with a large amount of jet water. Further, in the section AA, the bottom net of the bucket 58 rises at both ends so that food can be easily received, as shown in FIG. When such a mechanism is used, a large amount of cleaning, sterilization, and deodorizing treatment can be performed in a short time. At this time, the amount of jet water from the upper side is large and the thickness of the water flow is large. If air is mixed into the water flow from above, the water jet is given more powerful washing.

図5は食材の洗浄、殺菌後のバケットコンベアー50の被洗浄殺菌物7の次工程への排出部を拡大したものである。
又、食材56は搬送コンベアー51から供給されるが、供給方法には制限されず、被洗浄殺菌物7を単純に均一にする、連続的な送り込み方式の搬送コンベアー51である。
FIG. 5 is an enlarged view of the discharge part of the bucket conveyor 50 after the cleaning and sterilization of the food to the next process of the sterilized product 7 to be cleaned.
The food 56 is supplied from the conveyor 51, but is not limited to the supply method, and is a continuous feeding type conveyor 51 that simply makes the sterilized product 7 to be cleaned uniform.

図6及び図7はA−A間とB−B間にバケットの底のアミ部分と両サイドのこぼれ防止板57の位置を示す。図8はバケットの底アミ58が、搬入コンベアー51から食材を受け取る時の状態A−A間でどのようになっているかを示している。又、図4におけるアジャスター59によって水面の上下位置調整をおこない、その上流側で、細かいメッシュの捕捉網63による、虫や異物の捕捉をおこなうと良い。新しい殺菌水は供給管60から供給される、  6 and 7 show the position of the bottom portion of the bucket and the spill prevention plates 57 on both sides between AA and BB. FIG. 8 shows how the bucket bottom 58 is in a state A-A when food is received from the carry-in conveyor 51. Further, the vertical position of the water surface is adjusted by the adjuster 59 in FIG. 4, and insects and foreign substances are captured by the fine mesh capturing net 63 on the upstream side. New sterilizing water is supplied from the supply pipe 60.

次にこのような構成からなる本実施の形態の洗浄、殺菌、脱臭作用について説明する。 殺菌水の水面に激しい水激を加えると、水面は波立つばかりでなく、水激によって多量の気泡24(図3に図示)を生成する、又、水激は水面下にも激しい攪拌作用と、水面を叩くことから生まれる振動作用を与え、これらが、食材に同時に働き、洗浄と殺菌の2工程が同時におこなわれる。古来より洗濯などでは、棒で叩く方法が知られているが、水激によって食材と水面を叩く方法は極めて高い洗浄効果をもたらす。このため、水激作用は噴射ノズルを出来るだけ水面に近づける方法が良い、また水流中にエアーを吹き込むと水激力が強化される。また、噴射ノズル位置が被洗浄殺菌物の大きさにより任意に高さ調整ができるものが良い、このための機構を図9及び図15、図16などには具備している。ただし、図9にはその機構を図示せず。  Next, the cleaning, sterilization, and deodorizing actions of the present embodiment having such a configuration will be described. When an intense water is applied to the surface of the sterilizing water, the water surface not only swells, but also generates a large amount of bubbles 24 (shown in FIG. 3). The vibration effect generated by hitting the water surface is given, and these act on the food at the same time, and the two steps of washing and sterilization are performed simultaneously. Since ancient times, a method of tapping with a stick has been known for washing and the like, but a method of tapping food and water with water is very effective in cleaning. For this reason, it is good to make the jet nozzle as close to the surface of the water as possible, and when the air is blown into the water stream, the water power is strengthened. Further, it is preferable that the position of the spray nozzle can be arbitrarily adjusted depending on the size of the sterilized material to be cleaned. A mechanism for this purpose is provided in FIGS. However, the mechanism is not shown in FIG.

又、この時、発生する大量の泡は大小無数の形状となり、その消滅と発生により生まれる微弱な超音波や振動波が食材の表面に付着した水の臨界膜を除去して、細菌や、虫、異物などを殺菌水と良く反応させながら、効率的に除去する。一般にこうして発生する気泡は、消滅時に微弱な超音波が発生する事が知られている。  At this time, a large amount of bubbles are generated, and countless shapes are formed. The weak ultrasonic waves and vibration waves generated by the disappearance and generation of the bubbles remove the critical film of water adhering to the surface of the food, and bacteria and insects. Efficiently remove foreign substances while reacting well with sterilized water. In general, it is known that the bubbles generated in this way generate a weak ultrasonic wave when disappearing.

この時、噴射水激25は斜めから与えており。真上から与えるよりも気泡が大量に発生する。又、発生する気泡郡は、真上から与える噴射水激26は水面を激しく叩くため、水面下に振動波として伝達する。又、噴射水激の水流の太さと強さを変えることを合せ用いることにより、今までに、なかった洗浄と殺菌の効果が得られる。尚、この水流の中にエアーを混合させて一層強力な状態にしても良い。また、水面下部から気泡が上昇してくると段々と気泡は大きくなる、この気泡を上方から激しく水激で叩きながら破壊すると、その破裂衝撃作用が被洗浄殺菌物の洗浄効果をより強力にする。こうした機構を図1、や図9、等の装置に組み込むと更に好ましい。  At this time, the water jet 25 is given from an angle. A lot of bubbles are generated rather than giving from right above. Further, in the generated bubble group, the jet water fire 26 given from directly above strikes the water surface violently, so that it is transmitted as a vibration wave below the water surface. In addition, by combining and changing the thickness and strength of the water jet, the cleaning and sterilizing effects that have never been obtained can be obtained. It should be noted that air may be mixed into this water flow to make it stronger. In addition, when bubbles rise gradually from the bottom of the water surface, the bubbles gradually increase. If this bubble is destroyed while striking it with water, the bursting impact action will make the cleaning effect of the sterilized material to be cleaned stronger. . It is more preferable to incorporate such a mechanism in the apparatus shown in FIGS.

又、水温が10℃でも炭酸水は炭酸濃度が2000ppm以上になると発泡化現象が何もしなくも起こりやすく、家庭の炭酸飲料やビールなどは4000ppm以上であるが炭酸が抜けても、しばらくの間、炭酸ガスの泡が出続ける発泡作用は広く知られているのと同じである。この発泡作用が次亜塩素酸や二酸化塩素などによる殺菌後の塩素臭を吹き飛ばして食味、食感の良い製品の生産に役立つものである。  Even when the water temperature is 10 ° C., the carbonated water tends to cause a foaming phenomenon when the carbonic acid concentration is 2000 ppm or higher, and the household carbonated beverages and beer are 4000 ppm or higher. The foaming action in which carbon dioxide bubbles continue to be produced is the same as that widely known. This foaming action blows off the chlorine odor after sterilization with hypochlorous acid, chlorine dioxide, etc., and helps to produce a product with a good taste and texture.

しかし、高濃度炭酸水を手軽に大量に得るのが難しかった。それは、従来、水中に炭酸ガスを吹き込む方式であったためで、一定の濃度が必要な飲料水には良いが、野菜洗浄工程には向かなかった、また、連続的に大量に使う業界がなかったため、このためこの様な技術ノウハウが開発されなかった。
新しい方法として、今までの水中に炭酸ガスを吹き込む方式とは逆に、2kg/cm2程度の炭酸ガス空間に、シャワー状に噴霧して吸収効率を高め、この処理を循環式でおこなうことにより、炭酸水による発泡脱臭処理が、容易におこなえるようにしたものである。
また、炭酸ガスの消費量を押さえるためには、炭酸ガス圧力を1センチメートル平方当たり0.5キログラム以下まで下げても十分に炭酸水を生成できる。
However, it was difficult to easily obtain a large amount of high-concentration carbonated water. This is because it used to blow carbon dioxide into water, so it is good for drinking water that requires a certain concentration, but it is not suitable for vegetable washing processes, and there is no industry that uses large amounts continuously. For this reason, such technical know-how was not developed.
As a new method, contrary to the conventional method of blowing carbon dioxide into water, spraying it into a carbon dioxide gas space of about 2 kg / cm2 in a shower shape to increase the absorption efficiency, and by performing this treatment in a circulating manner, The foam deodorization treatment with carbonated water can be easily performed.
Moreover, in order to suppress the consumption of carbon dioxide, carbonated water can be sufficiently generated even if the pressure of carbon dioxide is lowered to 0.5 kg or less per centimeter square.

又、この炭酸水による脱臭処理を、炭酸水の水面近傍の位置に保たれた食材に対して、激しい噴射水激を加えておこなうと、大量の気泡が発生する。炭酸濃度が低くても十分な発泡作用がえられる。また、この状態に於ける、水面の直ぐ下は、激しい攪拌作用と振動が伝わり、低濃度の炭酸水でも、通常の洗浄水より、この発泡作用により被洗浄殺菌物7の表面で、小さな気泡となり、洗浄と脱臭効果が高くなる。ここでは、水面近傍に被洗浄殺菌物7を保持して塩素臭の除去を行うようにしたが、単に炭酸水のシャワーを被洗浄殺菌物7に当てて洗浄しても発泡効果により脱臭を容易に行うことが可能である。他の効果として、野菜などの植物は水中の炭酸ガスを吸収できるため、パリパリ感が増大して野菜品質の向上を見られる。  In addition, if this deodorizing treatment with carbonated water is performed by applying intense spraying water to the food material kept in the vicinity of the carbonated water surface, a large amount of bubbles are generated. Even if the carbonic acid concentration is low, a sufficient foaming action can be obtained. In this state, just below the water surface, vigorous stirring action and vibration are transmitted, and even in low-concentration carbonated water, small bubbles are generated on the surface of the sterilized article 7 to be cleaned by this foaming action than ordinary washing water. And the cleaning and deodorizing effect is enhanced. Here, the sterilized material 7 to be cleaned is held near the surface of the water to remove the chlorine odor. However, even if the carbonated water shower is simply applied to the sterilized material 7 to be cleaned, deodorization is easy due to the foaming effect. Can be done. As another effect, plants such as vegetables can absorb carbon dioxide in water, so that the crispness is increased and the vegetable quality is improved.

図9は請求項1に関連する方法、及び請求項13に関連する装置であるが、洗浄殺菌を行う工程から発生する炭酸ガスを再利用する機構として、前記工程部分の入り口と出口共に、のれん式の遮断を供えた炭酸ガス回収機構を備えた、殺菌炭酸洗浄化システム100の実施例を示す。本システム図は殺菌水生成装置122で供給原水配管102から供給される水道水又は井水が次亜塩素酸濃度200ppm程度に調整されて、洗浄機タンク104に供給され、更に給水手動バルブ103で、原水が供給され濃度調整されるように成っている。また、殺菌水は濃度の減少分に応じて殺菌水タンク123から供給される。  FIG. 9 shows a method related to claim 1 and an apparatus related to claim 13. As a mechanism for reusing the carbon dioxide gas generated from the process of cleaning and sterilization, both the entrance and the exit of the process part are goodwill. 1 shows an embodiment of a sterilizing carbon dioxide cleaning system 100 equipped with a carbon dioxide gas recovery mechanism provided with a shut-off of a formula. In this system diagram, tap water or well water supplied from the supply raw water pipe 102 by the sterilizing water generator 122 is adjusted to a hypochlorous acid concentration of about 200 ppm, supplied to the washing machine tank 104, and further supplied by a water supply manual valve 103. The raw water is supplied and the concentration is adjusted. The sterilizing water is supplied from the sterilizing water tank 123 according to the decrease in concentration.

所定の水位に達すると虫取り部126などにオーバーフローして回収管127に入り、U字配管部105を通る、U字配管部は装置内の、空気や炭酸ガスが、外部に逃げないように、水により遮断するためのもので、この部分に水をためてガスが機械外部に逃げないようにしてある。  When it reaches a predetermined water level, it overflows into the insect catching section 126 and enters the recovery pipe 127 and passes through the U-shaped piping section 105. The U-shaped piping section prevents air and carbon dioxide in the apparatus from escaping to the outside. In order to shut off with water, water is accumulated in this part so that gas does not escape to the outside of the machine.

水路は次に、異物除去器106に入り、小さな虫や土、ゴミ、などが濾過されて、循環ポンプ107に入り、循環水供給路109により一方は最終の洗い工程に供給され、配置してある数個の噴射ユニット118から激しく噴射されて洗浄と殺菌が行われる。  The water channel then enters the foreign matter remover 106, where small insects, dirt, dust, etc. are filtered and enter the circulation pump 107, one of which is supplied to the final washing process by the circulating water supply channel 109 and arranged. Cleaning and sterilization are performed by violently ejecting from several injection units 118.

他方は回収水路系111を通って、荒取供給管113を通って、入り口部の荒取り工程に数個の噴射ユニット118から被洗浄殺菌素材131に激しく吹き付けられる、また、噴射水流は水面に激突して、攪拌と振動波や多量の泡を生成する。この激しい洗浄作用がゴミや微細な塵などを取り除く。  The other passes through the recovery water channel system 111, passes through the roughing supply pipe 113, and is blown violently from the several spraying units 118 to the sterilized raw material 131 to be cleaned in the roughing process at the entrance. Clash and generate agitation and vibration waves and a lot of bubbles. This intense cleaning action removes dust and fine dust.

この時、被洗浄殺菌素材131をささえる、水面より下にあるコンベアーの上面より下に、噴射管129が配置され、図3に示した回転羽根21の代わりに噴射管が多数取り付けられている。これにより、下側からも攪拌と洗浄と殺菌の効果が加えられるようにしてある。  At this time, the injection pipe 129 is arranged below the upper surface of the conveyor below the water surface that supports the sterilization material 131 to be cleaned, and a number of injection pipes are attached instead of the rotary blades 21 shown in FIG. Thereby, the effect of stirring, washing, and sterilization can be added also from the lower side.

循環水供給路109に循環ポンプ107から加圧供給される流量と荒取供給管113に供給される流量との、2つに、分岐供給されるトータル量、とは別に、他方、回収水路系111にある、炭酸槽給水バルブ112を開けると、高圧ポンプ115から第一炭酸生成タンク116の上部空間に噴射される。この空間には高圧炭酸ボンベ121から供給された炭酸ガスが充満している。また、排水時にタンク内の炭酸ガスが、炭酸水と一緒に排出されないように、タンの下部には、一定の水位で、生成された炭酸水が貯留されている。  In addition to the total amount that is branched and supplied to the circulating water supply passage 109, the flow rate that is pressurized and supplied from the circulation pump 107 and the flow rate that is supplied to the roughing supply pipe 113, the recovery water channel system When the carbonate tank water supply valve 112 at 111 is opened, the high pressure pump 115 injects it into the upper space of the first carbonate generation tank 116. This space is filled with carbon dioxide gas supplied from the high-pressure carbon dioxide cylinder 121. Further, the generated carbonated water is stored at a constant water level in the lower part of the tank so that the carbon dioxide gas in the tank is not discharged together with the carbonated water during drainage.

この炭酸水は第二炭酸生成タンク116−Aの上部高圧炭酸ガス空間に再び噴霧される、この時、噴射圧は第一炭酸生成タンク116が第二炭酸生成タンク116−Aより高圧にしてあっても良いし、また、連結の途中にポンプを配置して再度加圧しても良い。ここでは、二段にして、炭酸ガスの溶存量が、より高い濃度になるように成っている。通常は一段でも良いが、直列に生成タンク116を2基取り付けなくても2基を並列に配管して流量を大きく取れるようにしても良い。  This carbonated water is sprayed again into the upper high pressure carbon dioxide gas space of the second carbonate production tank 116-A. At this time, the injection pressure is set so that the first carbonate production tank 116 has a higher pressure than the second carbonate production tank 116-A. Alternatively, a pump may be arranged in the middle of connection to pressurize again. Here, in two stages, the dissolved amount of carbon dioxide gas has a higher concentration. Normally, one stage may be used, but two production tanks 116 may not be attached in series, but two pipes may be piped in parallel to increase the flow rate.

高濃度の炭酸水に調整されて、炭酸水供給路117から高圧状態で、殺菌洗浄管135に送られ、多数の噴射ユニット118下部の水面134と被洗浄殺菌物131に激しく噴射されて、炭酸ガスの発泡作用の洗浄力が加えられながら殺菌も行なわれる。また、この高濃度の炭酸水は噴射管129に供給されても良い(図示せず)。この時、被洗浄殺菌物131を水面近傍に維持して搬送するネットコンベアー124は駆動源ごと搬送洗浄物と水面の調整が出来るよう、上下に高さ調整が出来るように構成されている。  It is adjusted to high-concentration carbonated water, sent from the carbonated water supply path 117 to the sterilization washing pipe 135 in a high-pressure state, and violently jetted onto the water surface 134 and the sterilized product 131 to be cleaned at the bottom of many injection units 118, Sterilization is also performed while the detergency of the gas foaming action is applied. Further, this high-concentration carbonated water may be supplied to the injection pipe 129 (not shown). At this time, the net conveyor 124 that conveys the sterilized article 131 to be cleaned while maintaining the vicinity of the water surface is configured so that the height of the net can be adjusted up and down so that the conveyance cleaning object and the water surface can be adjusted for each drive source.

また、炭酸水の持つpH領域が、ちょうど、次亜塩素酸溶液において、強力な殺菌力が発生するpH5〜6の領域と、重なっているため生産工程上、安定したpH管理が行なえるものであり、炭酸ガスは水中で炭酸を生成しpH5〜6の間で強力な緩衝作用を生み出すため、安定した殺菌洗浄が行なえる。この時、井水の使用で原水のアルカリ性が強くpH8近くある場合などでも、殺菌水生成装置122の他に希塩酸添加による原水pH調整装置の必要がない。  In addition, since the pH range of carbonated water overlaps with the pH range of 5 to 6 where strong sterilizing power is generated in a hypochlorous acid solution, stable pH control can be performed in the production process. Yes, carbon dioxide produces carbonic acid in water and produces a strong buffering action between pH 5 and 6, so that stable sterilization washing can be performed. At this time, even when the raw water is strongly alkaline and has a pH close to 8 due to the use of well water, there is no need for a raw water pH adjusting device by adding dilute hydrochloric acid in addition to the sterilizing water generating device 122.

殺菌洗浄室157は炭酸水が噴射されて気化した炭酸ガスが、出来るだけ、炭酸空気分離装置101により、再利用できるために、SUS316や樹脂製などの耐蝕性素材により囲われていて、密閉空間となっている。この機構においては、被洗浄殺菌素材131の入り口部と出口部に、開閉膜159が、各々に装着されている。  The sterilization washing chamber 157 is surrounded by a corrosion-resistant material such as SUS316 or resin so that carbon dioxide vaporized by injection of carbonated water can be reused by the carbon dioxide air separation device 101 as much as possible. It has become. In this mechanism, an opening / closing film 159 is attached to each of an entrance and an exit of the material to be cleaned 131.

一連式搬送コンベアーの両側には被洗浄殺菌物131が気泡に包まれた、虫やゴミと一緒に両側の排水部136に流れ込まないように、コンベアーの両側に水を通す、何枚ものガイド板152(図15に図示)があり、さらにコンベアーが駆動ローラにより回転する部分で互いにぶつかりあわない構造になっている。  A number of guide plates that allow water to pass through the sides of the conveyor so that the sterilized product 131 to be cleaned is wrapped in air bubbles on both sides of the series conveyor, so that it does not flow into the drains 136 on both sides together with insects and dust 152 (shown in FIG. 15), and the conveyor does not collide with each other at the portion rotated by the driving roller.

図10においては請求項24に関する装置に付いて水流式搬送手段を示す。
これは、水面134近傍の被洗浄殺菌物131を下側から、被戦場殺菌物を支えながら搬送するものである。ネットコンベアー17やバケットコンベアー50などを使用しないで、水流により被洗浄殺菌物131を浮かせながら、水面134近傍での洗浄殺菌を行なうようにしたもので、水流コンベアー素子140(図13に図示)の外側に噴出し方向管119が在り、その内側で、噴出しパイプ119−Aが回転自在に装着されていて、水流コンベアー素子140が搬送方向に対して直角方向に多数ほぼ平行に設置されている。その上方向の一部がスリット状に開口している。被洗浄殺菌物131は殺菌水の流れ132に浮かせられて大きな矢印の方向に搬送される。図11は非洗浄物が沈まないように、洗浄物の下に水流の通過できる穴またはスリットを有する支え板130が設けられている機構を示す。
In FIG. 10, a water flow type conveying means is shown for the apparatus according to claim 24.
This conveys the to-be-cleaned sterilized product 131 near the water surface 134 from below while supporting the sterilized to-be- battlefield. Without using the net conveyor 17 or the bucket conveyor 50, the sterilized product 131 to be cleaned is floated by the water flow, and the cleaning sterilization is performed in the vicinity of the water surface 134. The flow conveyor element 140 (shown in FIG. 13) There is an ejection direction pipe 119 on the outer side, and an ejection pipe 119-A is rotatably mounted on the inner side, and a large number of water flow conveyor elements 140 are installed substantially parallel to the direction perpendicular to the conveying direction. . A part of the upper direction opens in a slit shape. The sterilized product 131 to be cleaned is floated in the sterilized water flow 132 and conveyed in the direction of a large arrow. FIG. 11 shows a mechanism in which a support plate 130 having a hole or a slit through which a water flow can pass is provided under the cleaning object so that the non-cleaning object does not sink.

噴出し方向管119の中には図13に示すように長穴142が全周に開口している、噴出しパイプ119−Aが、各々の噴出し方向管119の中に挿入されている。この噴出しパイプ119−Aの中に炭酸水と成っている次亜塩素酸濃度が約1000ppmから2000ppm程度の高濃度殺菌水が圧力送水されている。  As shown in FIG. 13, an ejection pipe 119 -A having a long hole 142 opened to the entire circumference is inserted into each ejection direction pipe 119. High-pressure sterilized water having a hypochlorous acid concentration of about 1000 ppm to about 2000 ppm, which is carbonated water, is pressure-fed into the ejection pipe 119-A.

このように図10〜図13は水流コンベアー140の運転状態を示す。被洗浄殺菌物131の搬送は、内側の噴出しパイプ119−Aが、パイプ内に図示した矢印のように回転すると、噴出し方向管119の、外側の水流は矢印132のように被洗浄殺菌物131に働き、下から吹き上げながら搬送の作用を生み、大きな矢印の方向に被洗浄殺菌物131を下から支えながら送り出す。もちろん、噴出しパイプ119−Aは被洗浄殺菌物131を下から支えながら大きな矢印方向に送り出せれば回転自在でなくてもよい。  10 to 13 show the operation state of the water flow conveyor 140 as described above. When the inner ejection pipe 119-A rotates as indicated by the arrow shown in the pipe, the outer water flow of the ejection direction pipe 119 is cleaned and sterilized as indicated by the arrow 132. It works on the object 131 and produces a conveying action while blowing up from below, and sends out the sterilized article 131 to be cleaned from below in the direction of a large arrow. Of course, the ejection pipe 119-A does not have to be rotatable as long as it can be sent out in the direction of a large arrow while supporting the sterilized product 131 to be cleaned from below.

また、噴出し方向管119を上下できるようにしておくことが好ましく、被洗浄殺菌物131の大きさが変化しても、水面から所定の位置において搬送することができるので、被洗浄殺菌物131の大きさが異なる場合でも、水面近傍においてのみ得られる洗浄効果が期待できる。  Moreover, it is preferable that the ejection direction pipe 119 can be moved up and down, and even if the size of the sterilized product 131 to be cleaned changes, it can be conveyed from the water surface at a predetermined position. Even when the sizes of the water are different, a cleaning effect obtained only in the vicinity of the water surface can be expected.

図11は図10において示されたような、水流コンベアー素子140を多数併設した、水流式搬送手段において、被洗浄殺菌物131が沈まずに確実に送られるように支え板130を搬送の補助機能として装備しているものの実施例である。  FIG. 11 shows an auxiliary function of conveying the support plate 130 so that the sterilized material 131 to be cleaned can be reliably sent without sinking in the water flow type conveying means provided with a large number of water flow conveyor elements 140 as shown in FIG. It is an example of what is equipped as.

図14においては、請求項25の機構を示した搬送手段の一部であり、水面近傍の位置で搬送する機構又は所定の水面下の深度を保持して搬送する機構が、羽根車等の回転部材を平行に配置し、該回転部材の軸部又は羽部の噴射孔から水流を噴射させる回転式噴射水流発生具よる構造の図である。被洗浄殺菌物を水面近傍に維持する上下位置調節が自在なガイドネット板17があり、水流により矢印方向(左方向)に搬送できるように、下側からは噴射管16より水流及び気泡が噴出され、回転羽根21の回転により矢印方向(左方向)への水流を作る構造となっている。  In FIG. 14, the mechanism that is a part of the transport means showing the mechanism of claim 25 and that transports at a position near the water surface or transports while maintaining a predetermined depth below the water surface is the rotation of an impeller or the like. It is a figure of the structure by the rotary injection water flow generator which arrange | positions a member in parallel and injects a water flow from the injection hole of the axial part or wing | blade part of this rotation member. There is a guide net plate 17 that can adjust the vertical position to maintain the sterilized material to be cleaned in the vicinity of the water surface. From the lower side, water flow and bubbles are ejected from the injection pipe 16 so that it can be conveyed in the arrow direction (left direction) by the water flow. Thus, the water flow in the arrow direction (left direction) is created by the rotation of the rotary blade 21.

このガイド軸として羽根車軸21があり、この内側から炭酸を含有する殺菌水が、きり欠き21−Bから噴射され、さらに回転羽根21−Aが回転することにより被洗浄殺菌物131を矢印の方向(左方向)に搬送する流れを作る。  There is an impeller shaft 21 as this guide shaft, sterilizing water containing carbonic acid is sprayed from the notch 21-B from the inside, and the rotating blade 21-A further rotates, so that the sterilized product 131 to be cleaned is in the direction of the arrow. Create a flow to be conveyed (left direction).

水に沈む野菜の場合はガイド板22−Aでガイドされながら回転羽根21−Aの回転を逆にすることで破線の矢印の方向(左方向)に被洗浄殺菌物131(7)を搬送する。  In the case of vegetables submerged in water, the sterilized product 131 (7) to be cleaned is conveyed in the direction of the broken arrow (left direction) by reversing the rotation of the rotary blade 21-A while being guided by the guide plate 22-A. .

図14を有する洗浄殺菌機においても図9の殺菌洗浄室157のように炭酸水が噴射されて気化した炭酸ガスが、出来るだけ、炭酸空気分離装置101により、再利用できるように、SUS316や樹脂製などの耐蝕性素材により殺菌洗浄室157が囲われた密閉空間で、被洗浄殺菌物7(131)の入り口部と出口部に、図9のように開閉膜159が、各々に装着されていると好ましい。  In the cleaning and sterilizing machine having FIG. 14, SUS316 or resin is used so that the carbon dioxide gas, which is vaporized by injection of carbonated water as in the sterilizing and cleaning chamber 157 of FIG. In a sealed space in which the sterilization / cleaning chamber 157 is surrounded by a corrosion-resistant material such as a product, an opening / closing film 159 is attached to each of the entrance and exit of the sterilized product 7 (131) to be cleaned as shown in FIG. It is preferable.

図15は本発明のもう一つの代表的な具体例に付いて示す。
水流方式やバケット方式の搬送手段でないネットコンベアー方式の搬送手段を有するものに関する、高濃度次亜塩素酸や亜塩素酸による、野菜などの殺菌洗浄及び脱臭機構を有する連続式食材洗浄殺菌脱臭装置160を示す。
本装置の殺菌洗浄を行う部分が液面上の密閉空間Cにおいて外部と遮断できるように被洗浄殺菌物の入り口部と出口部にウオーターカーテン5が整流器6から作られるよう殺菌水を供給する管路172に設けられたバルブ172−2で流量を調製できるようにしてあり、密閉空間Cの他の部分は炭酸ガスが外部に逃げないように密閉カバー(全体を図示せず)で覆われて密閉空間Cを形成している。
この密閉カバーの上部には外部に空気を排出するバルブ(図示せず)が配置され、運転初期に残留する空気を、重い炭酸ガスが下部から溜まっていき上部から空気が抜けるように、自動、手動何れでも選択できるよう、電気的にコントロールできる構成になっている。この密閉空間Cに蓄積され濃度が高くなった炭酸ガスが殺菌洗浄の噴射ノズルから出る液粒子や激しい水激により液面から発生する霧等を介して次亜塩素酸塩の水溶液や次亜塩素酸水溶液に再吸収されて、炭酸ガスの消費を減らすように構成されている。亜塩素酸塩の水溶液を使用する場合も同様である。
FIG. 15 shows another representative embodiment of the present invention.
Continuous food cleaning sterilization deodorizing apparatus 160 having a mechanism for sterilization cleaning and deodorization of vegetables and the like with high-concentration hypochlorous acid or chlorous acid related to those having a net conveyor system transport means that is not a water flow system or bucket system transport means Indicates.
A pipe for supplying sterilizing water so that the water curtain 5 is formed from the rectifier 6 at the inlet and outlet of the sterilized material to be cleaned so that the part to be sterilized and cleaned can be shut off from the outside in the sealed space C on the liquid surface. The flow rate can be adjusted by a valve 172-2 provided in the passage 172, and the other part of the sealed space C is covered with a sealed cover (the whole is not shown) so that the carbon dioxide gas does not escape to the outside. A sealed space C is formed.
A valve (not shown) for exhausting air to the outside is arranged at the top of this hermetic cover, so that air that remains in the initial stage of operation automatically collects from the lower part of the carbon dioxide and escapes from the upper part. It can be electrically controlled so that it can be selected manually. Hypochlorite aqueous solution or hypochlorous acid is accumulated in the sealed space C through the liquid particles coming out of the sterilizing and cleaning jet nozzle or the mist generated from the liquid surface due to intense water violence. It is reabsorbed by the acid aqueous solution to reduce the consumption of carbon dioxide gas. The same applies when an aqueous solution of chlorite is used.

樹脂製のネットコンベアー167の上面側の水平部分が、殺菌洗浄槽166内に葉物野菜などのように水に沈む性質の被洗浄殺菌物131を水面近傍に保持しながら搬送できるように水面より沈んだ位置に配置され、その両側に水が通すり抜けられる、何枚ものガイド側板152があり、コンベアーが駆動ローラにより回転する部分で互いにぶつかりあわないようになっている。  The horizontal part on the upper surface side of the resin-made net conveyor 167 allows the sterilized washing tank 166 to transport the sterilized article 131 having the property of sinking into water, such as leafy vegetables, while holding it near the water surface. There are a number of guide side plates 152 that are arranged in a sinking position and through which water can pass, so that the conveyors do not collide with each other at the part rotated by the drive roller.

但し、ゴミや虫、髪の毛などの除去は、ガイド側板152より上を水面に浮いたゴミ等が乗り越える状態で搬送し、その過程で上方からの水激で、図9で図示すような形で、排水部136や虫取り部126に流れ出すようにして、取り除ける機構を有している。また、この排水過程でヘアーキャッチャーを流路内に装備するのが良い。この時、野菜が流失しないように防御網などをガイド側板152の内側に位置して取りつけるとより好ましい。However, the removal of dust, insects, hair, etc. is carried in a state where dust etc. floating above the guide side plate 152 gets over the surface of the water, and in the process, the water is intense from above, in the form shown in FIG. , And a mechanism that can be removed so as to flow out to the drainage part 136 and the insect catching part 126. In addition, a hair catcher is preferably installed in the flow path during this drainage process. At this time, it is more preferable that a protective net or the like is mounted on the inner side of the guide side plate 152 so that vegetables are not washed away.

また、葉物野菜などの大きさと投入量により水面から被洗浄殺菌素材131が露出しないようにネットコンベアー167の高さを調節できるように、上下動モータ180の回転がタイミングベルト183を介して伝わる4本の上下送りネジ176の回転により、2個の上下移動ローラ179の両端に配置された4箇所の雌ネジ178が上下に移動され、その結果ネットコンベアー167を上下に調整できるようになっている。  Further, the rotation of the vertical movement motor 180 is transmitted via the timing belt 183 so that the height of the net conveyor 167 can be adjusted so that the sterilized material 131 to be cleaned is not exposed from the water surface depending on the size and input amount of leafy vegetables and the like. By rotating the four vertical feed screws 176, the four female screws 178 disposed at both ends of the two vertical movement rollers 179 are moved up and down, so that the net conveyor 167 can be adjusted up and down. Yes.

上下送りネジ176は複数の噴射ノズル14が前後左右に規則的に多数配置されたノズル集合管175を上下に高さ調整ができるように、集合管雌ネジ177に管上下モータ181の回転がタイミングベルト184を介して伝達され、上下動モータ180が停止している時に、集合管目ネジ177を回転させ、これに設置されているノズル集合管175を上下して水面からの高さを調整できるようになっている。この時、上下移動ローラ179と同時に動かしたい場合は、上下動モータ180と管上下モータ181を減速機付のパルスモータなどで構成し、両者の回転を予めシーケンサーなどにプログラムし、それぞれの高さを数値として、操作パネルなどから、任意に設定すれば自動的に所定の高さに成るようにしても良い。  The vertical feed screw 176 has a timing of rotation of the pipe vertical motor 181 to the collective pipe female thread 177 so that the height of the nozzle collective pipe 175 in which a plurality of spray nozzles 14 are regularly arranged in the front, rear, left and right can be adjusted up and down. When the vertical movement motor 180 is transmitted through the belt 184 and the vertical movement motor 180 is stopped, the collecting pipe screw 177 is rotated, and the nozzle collecting pipe 175 installed on this is moved up and down to adjust the height from the water surface. It is like that. At this time, if it is desired to move the vertical movement roller 179 at the same time, the vertical movement motor 180 and the pipe vertical motor 181 are constituted by a pulse motor with a speed reducer, and both rotations are programmed in advance in a sequencer or the like, and the respective heights are set. As a numerical value, if it is arbitrarily set from an operation panel or the like, it may be automatically set to a predetermined height.

また、この連続式食材洗浄殺菌脱臭装置160のネットコンベアー167はコンベアー上面に垂直でコンベアーの進む方向に直行するように複数の区切り板168が、被洗浄殺菌物131がムラ無く搬送される目的で設置されている。この区切り板168の根元部分は硬い樹脂で構成し全高さの半分以上が軟質の樹脂が取り付けるように形成し、柔らかく下部搬送板166を擦る様に動かしても良い。  In addition, the net conveyor 167 of the continuous food cleaning sterilization deodorizing apparatus 160 has a plurality of separators 168 so that the sterilized material 131 to be cleaned is conveyed evenly so that it is perpendicular to the upper surface of the conveyor and goes straight in the direction of the conveyor. is set up. The base portion of the partition plate 168 may be made of a hard resin and formed so that a soft resin is attached to more than half of the total height, and the lower conveying plate 166 may be moved softly and rubbed.

ネットコンベアー167は回転速度を任意に変更できるように制御系が構成さており、しかも、回転方向を正逆いずれも選択可能になっていて上面側では葉物野菜などの水に沈む物で、ネットコンベアー167の下側には気泡管169と殺菌水噴射管16が交互に配置され、気泡管169からは、Aから気化した炭酸ガスを吸引する炭酸ガスブロアーから供給される炭酸ガスを含んだ空気が噴出する。これにより、気化した炭酸ガスを再度殺菌水中に溶かし込むことができ、炭酸ガスの消費を抑えることができる。また、さらに下部にある噴射管16からも殺菌水流が噴出して気泡と水流でゴミなどが側面と下流側にある、排水トレイ41(図示せず)や排水管路201に流れ込むようにしてあり、この状態で水面近傍に被洗浄殺菌物131を保持して搬送するようになっている。搬送中に水面上方から水面に向かって、激しい水激を与え、これにより水中から上がってきた気泡を激しくたたいて破裂させ、振動波を発生させてより洗浄効果を高める。この時水面では、水激により発生する大量の泡と水の攪拌や振動で、洗浄効果がより高められながら、葉物野菜などの洗浄殺菌が行われる、この時、大量の霧が発生し、また噴射時に生成される殺菌水の微粒子と共に密閉空間Cに溜まった炭酸ガスが再吸収される。  The net conveyor 167 has a control system so that the rotation speed can be arbitrarily changed, and the rotation direction can be selected either forward or reverse. On the upper surface side, the net conveyor 167 is a thing that sinks in water such as leafy vegetables. Bubble tubes 169 and sterilizing water jet tubes 16 are alternately arranged below the conveyor 167. From the bubble tubes 169, air containing carbon dioxide supplied from a carbon dioxide blower that sucks carbon dioxide vaporized from A is supplied. Erupts. Thereby, the vaporized carbon dioxide can be dissolved again in the sterilized water, and consumption of the carbon dioxide can be suppressed. Further, a sterilizing water flow is also ejected from the lower injection pipe 16 so that dust and the like flow into the drainage tray 41 (not shown) and the drainage pipe 201 on the side and downstream sides by bubbles and waterflow. In this state, the sterilized product 131 to be cleaned is held and transported near the water surface. During transportation, a strong water violence is given from above the water surface to the surface of the water, thereby causing the bubbles rising from the water to violently rupture and generate a vibration wave to enhance the cleaning effect. At this time, washing and sterilization of leafy vegetables, etc. are performed while the cleaning effect is further enhanced by the agitation and vibration of a large amount of foam and water generated by water, and at this time, a large amount of fog is generated, Further, the carbon dioxide collected in the sealed space C together with the fine particles of sterilizing water generated at the time of injection is reabsorbed.

反対にキュウリ、トマト、ナス、ピーマンなどのように水に浮きやすい野菜はネットコンベアー167の回転方向を逆にして被洗浄殺菌物131をネットコンベアー167の下側に送り込み、水面より高い水圧がかかるようにして、例えばキュウリなどのイボイボやへたの中に殺菌水が浸透して短時間で殺菌が出来るようにしてある。 また、この時、一定の水圧と噴射管16からの強い水流が被洗浄殺菌物131近傍での殺菌水の攪拌作用を与え、殺菌と洗浄効果を高めるように成っている。  On the other hand, vegetables that float easily in the water, such as cucumbers, tomatoes, eggplants, peppers, etc., reverse the direction of rotation of the net conveyor 167 and send the sterilized product 131 to be cleaned to the lower side of the net conveyor 167 so that a higher water pressure is applied than the surface of the water. In this way, for example, sterilizing water penetrates into warts such as cucumbers and spats so that sterilization can be performed in a short time. Further, at this time, a constant water pressure and a strong water flow from the injection pipe 16 give a stirring action of sterilizing water in the vicinity of the sterilized product 131 to be cleaned, thereby enhancing the sterilizing and cleaning effect.

殺菌水は循環タンク200からストレーナー170でゴミを濾過され、殺菌循環ポンプ171により管路172を通り噴射管16へ供給されるとともに、水面上方から水面に向かって噴射する噴射ノズル14のノズル集合管175に供給される。殺菌洗浄槽165での洗浄殺菌工程の後に、殺菌洗浄槽166の下流にある排水管路201とサイドに在る排水トレイ41(図2に示すような形であるが図示せず)から排水され循環タンク200に戻る。また、殺菌洗浄槽の底の沈殿物を排出するため、ドレンバルブ203を適当な排水調整状態で開いておいても良い。これらの排水は虫取りアミ202で濾過されて循環タンク200に入る、この虫取りアミ202は簡単に外せて外で洗浄できるように循環タンク200の上に濾過アミの外周がパイプで加工された物が置いてあるだけにしてある。  The sterilizing water is filtered from the circulation tank 200 by the strainer 170, and is supplied to the injection pipe 16 through the pipe line 172 by the sterilization circulation pump 171, and the nozzle collecting pipe of the injection nozzle 14 that injects from the upper surface to the water surface. 175. After the washing and sterilization step in the sterilization washing tank 165, the water is drained from the drainage pipe 201 downstream of the sterilization washing tank 166 and the drain tray 41 located on the side (not shown). Return to the circulation tank 200. Further, in order to discharge the sediment at the bottom of the sterilization washing tank, the drain valve 203 may be opened in an appropriate drainage adjustment state. These wastewater is filtered by the insect catcher 202 and enters the circulation tank 200. The outer periphery of the filter catcher is processed by a pipe on the circulation tank 200 so that the insect catcher 202 can be easily removed and washed outside. There are only things left.

被洗浄殺菌物131の投入箇所には薄型ネットコンベアー191があり、葉物野菜においてはこの上で野菜を均一に並べながらネットコンベアー167に平均して乗るようにして投入する。また、浮く野菜の場合は薄型ネットコンベアー191を取り外すことにより殺菌洗浄槽166の手前側に生まれたスペースから野菜を投入する。投入された野菜はネットコンベアー167の下側を通って、殺菌洗浄工程が終了する。前記、葉物野菜はネットコンベアー167の搬出側の傾斜部に送られて上部から通常は1000ppm程度の炭酸含有水で殺菌水と、その塩素臭の洗い落し工程が行われながら搬出されるのが好ましい。  There is a thin net conveyor 191 at the place where the sterilized product 131 to be cleaned is placed. In the case of leafy vegetables, the vegetables are placed on the net conveyor 167 on average while they are arranged uniformly. In the case of floating vegetables, the vegetables are introduced from the space created on the front side of the sterilization washing tank 166 by removing the thin net conveyor 191. The input vegetables pass through the lower side of the net conveyor 167, and the sterilization washing process is completed. The leafy vegetables are sent to the inclined part on the carry-out side of the net conveyor 167, and are carried out from the upper part while the washing process of the sterilized water and its chlorine odor is usually performed with about 1000 ppm of carbonated water. preferable.

葉物野菜は炭酸タンク195から炭酸ポンプ192により噴射ノズル189と188に高圧で送り出された大量の炭酸水でネットコンベアー167から剥がされて下の薄型ネットコンベアー191に落ちて、噴射ノズル190からの炭酸含有水で再度洗われて、綺麗に塩素臭が取り除かれる。この時、噴射ノズル187や188からでた炭酸水はトレイ194で受けられて配水管194−aを通り、再び炭酸タンク195に戻るようになっている。炭酸タンク195内の炭酸水は絶えず供給されて一定の水位でオーバーフローするようになっているのが好ましい。  The leafy vegetables are peeled off from the net conveyor 167 by a large amount of carbonated water fed from the carbonate tank 195 to the spray nozzles 189 and 188 by the carbonate pump 192 and dropped onto the thin net conveyor 191 below. It is washed again with carbonated water to cleanly remove the chlorine odor. At this time, carbonated water from the injection nozzles 187 and 188 is received by the tray 194, passes through the water distribution pipe 194-a, and returns to the carbonate tank 195 again. The carbonated water in the carbonate tank 195 is preferably continuously supplied and overflows at a constant water level.

また、野菜などでも、モヤシや刻んだねぎ、にんじん、ごぼうの千切り等また、ラッキョウや梅、などのように流れて行き、排水に逃げてしまうような物はこれ等を編み籠や外からの洗浄力が作用できるような多数の窓が在るケージなどに入れて籠やケージごと殺菌するのが望ましい。この時は被洗浄殺菌物131の投入口の薄型ネットコンベアー191を変更できるようにそれぞれの被洗浄殺菌物131により入り口と出口をオプション装置として設計し取り付けるのがさらに好ましい。  Also, vegetables such as sprouts, chopped green onions, carrots, shredded burdock, etc. Also, things that flow like raccoon, plums, etc. It is desirable to sterilize the basket and the cage together in a cage having a large number of windows where the cleaning power can act. At this time, it is more preferable that the inlet and outlet are designed and attached as optional devices by the respective sterilized articles 131 to be cleaned so that the thin net conveyor 191 at the inlet of the sterilized articles 131 can be changed.

また、連続式食材洗浄殺菌脱臭装置160で使用される殺菌水は、次亜塩素酸水溶液からなる殺菌水であり、その生成工程はタンクに一定量の水を加えてから所定の濃度に成るように12%の次亜塩素酸ナトリウムを定量ポンプで添加し、希釈次亜塩素酸ナトリウム液を生成してから、次に所定の量の希塩酸を定量ポンプで一定量タンクに水と共に添加して、希釈された水溶液にして、これを前記、希釈次亜塩素酸ナトリウム液に混合攪拌して循環タンク200に供給する方法が塩素ガスの発生がないため、望ましい。 また、井戸水を使用する食材の洗浄工程が一般には多いため、井戸水のpHがよく弱アルカリ(pH8.6程度)の場合が多いため、塩酸でpH調整が必要であるが、この場合、塩酸の消費が水道水の利用時より多く必要に成る。しかし、この方式であれば塩酸定量ポンプの吐水量を多く成るように設定するだけで良い。  Further, the sterilizing water used in the continuous food cleaning sterilization deodorizing device 160 is sterilizing water composed of an aqueous hypochlorous acid solution, and the production process is such that a predetermined amount of water is added to the tank and a predetermined concentration is obtained. After adding 12% sodium hypochlorite with a metering pump to form a diluted sodium hypochlorite solution, a predetermined amount of dilute hydrochloric acid is then added to a fixed amount tank with water using a metering pump, A method of preparing a diluted aqueous solution and mixing and stirring the diluted aqueous solution of sodium hypochlorite and supplying it to the circulation tank 200 is desirable because there is no generation of chlorine gas. In addition, since there are generally many washing processes for ingredients using well water, the pH of the well water is often good and weakly alkaline (about pH 8.6), so it is necessary to adjust the pH with hydrochloric acid. More consumption is required than when using tap water. However, with this method, it is only necessary to set the amount of water discharged from the hydrochloric acid metering pump to be large.

また、本装置に於いては、炭酸ガスが充満した圧力タンクである炭酸水生成タンク30内で、シャワー状の噴射により炭酸ガスを溶解させると液中に軽く1000ppm程度の炭酸を生成する。炭酸水生成タンク30や密閉空間C内で液中に生成される炭酸が、100ppm以上炭酸を含有していると、pH6〜5の範囲で水素イオン濃度に対する緩衝性が明らかに判る程発現する、これを実験でグラフ化するために、重炭酸ナトリウムと塩酸を用いて炭酸を液中に生成させて高濃度の緩衝性を示す実験を行い、グラフ化したものが、図24と図25である。炭酸含有の殺菌水は 極めて高い濃度の次亜塩素酸水溶液、例えば4800ppmによる殺菌水が安定してpH5〜6の範囲で利用できることを確認した。本出願の発明者は図9に示した第一炭酸生成タンク116や第二炭酸生成タンク116−Aなどを使用して、炭酸含有の殺菌水の生成を行い次亜塩素酸のpH5.5周辺の急激な変化を防止する緩衝作用にも用いている、これにより、高濃度の次亜塩素酸例えば2000ppm程度の殺菌作業工程の安全を確保している。  In this apparatus, when carbon dioxide is dissolved by a shower-like jet in a carbonated water production tank 30 which is a pressure tank filled with carbon dioxide, carbon dioxide of about 1000 ppm is produced lightly in the liquid. When the carbonic acid produced in the liquid in the carbonated water production tank 30 or the sealed space C contains 100 ppm or more of carbonic acid, the buffering property against the hydrogen ion concentration clearly appears in the pH range of 6 to 5. In order to graph this in an experiment, FIG. 24 and FIG. 25 are graphs showing a high concentration buffering property by generating carbonic acid in liquid using sodium bicarbonate and hydrochloric acid. . As for the sterilizing water containing carbonic acid, it was confirmed that an aqueous solution of hypochlorous acid having a very high concentration, for example, sterilizing water with 4800 ppm, can be stably used in a pH range of 5-6. The inventor of the present application uses the first carbonic acid production tank 116 and the second carbonic acid production tank 116-A shown in FIG. 9 to produce carbonic acid-containing sterilizing water, and the pH of hypochlorous acid is around 5.5. It is also used for the buffering action to prevent a rapid change in the concentration, thereby ensuring the safety of the sterilization work process of high concentration hypochlorous acid, for example, about 2000 ppm.

重炭酸ナトリウムの場合、重炭酸ナトリウムの消費量が炭酸濃度に比例して増大し、炭酸生成に必要な塩酸量も当然増大する。重炭酸ナトリウムから炭酸を生成する場合は塩酸の供給のために新たに定量ポンプが必要になり、また、これら全てのコントロールに制御部分が高価で煩雑になる、また炭酸生成と同時に沢山の塩化ナトリウムが生成するため、高濃度の次亜塩素酸殺菌水を使用する殺菌洗浄工程においては、重炭酸ナトリウム水溶液をpH緩衝剤として実際の作業現場で使用するのは難しい。
そこで本発明者は副生成物の塩化ナトリウムができないで、しかも、食品添加物の法律的に問題が無く、しかも安全に高濃度の殺菌水を生成し、野菜、皿等の食材食器洗浄、殺菌、脱臭方法として、又、洗浄、殺菌、脱臭装置の構造として、炭酸ガスを圧力充填した空間に殺菌水あるいは水をシャワー状に噴射して殺菌水あるいは水に炭酸を含有させる方法および装置、又は、密閉空間Cで炭酸ガスを逃がさないようにして再吸収できる方法および装置にした。また、炭酸ガスを圧力充填したタンクを設けずに、前記密閉空間Cだけで炭酸ガスを溶解させることができるので、この密閉空間Cだけで装置を形成することが安全性およびコスト的に最も好ましい。
In the case of sodium bicarbonate, consumption of sodium bicarbonate increases in proportion to the concentration of carbonic acid, and naturally the amount of hydrochloric acid required for carbonic acid production also increases. When carbonic acid is produced from sodium bicarbonate, a new metering pump is required to supply hydrochloric acid, and the control part is expensive and complicated for all these controls. Therefore, it is difficult to use an aqueous sodium bicarbonate solution as a pH buffer at an actual work site in a sterilization washing process using high concentration hypochlorous acid sterilized water.
Therefore, the present inventor cannot produce sodium chloride as a by-product, and there is no legal problem with food additives, and it can safely produce high-concentration sterilized water, and wash and sterilize food dishes such as vegetables and dishes. As a deodorizing method, and as a structure of a cleaning, sterilizing and deodorizing apparatus, a method and apparatus for injecting sterilizing water or water in a shower-like manner into a space filled with carbon dioxide gas in a shower shape to contain carbon dioxide in the sterilizing water or water, or Thus, a method and an apparatus capable of reabsorbing carbon dioxide in the sealed space C so as not to escape are provided. Further, since the carbon dioxide gas can be dissolved only in the sealed space C without providing a tank filled with carbon dioxide gas under pressure, it is most preferable in terms of safety and cost to form an apparatus with only the sealed space C. .

図16に於いては、振動による気泡剥離機構を有する装置の説明である。
図15に示す装置のネットコンベアー167の下側より水流及び空気噴射を行う代わりに、炭酸ガスの気泡が一定の大きさに成長したとき、ネットコンベアー167に衝撃的な振動を与え、被洗浄殺菌物131から気泡を剥離させて気泡体積が移動してできる空間に、瞬間的に殺菌水が浸透する作用を利用し、キュウリのイボの中まで、殺菌水を浸透させて殺菌効率を高めるものであり、図15と同じように交互に配置された噴射管16及び気泡管169の下部にストッパー206を設け、ネットコンベアー131の内側にある突起207と一定時間ごとにぶつかってネットコンベアーに衝撃的な振動が発生するようにしたものである。
FIG. 16 illustrates an apparatus having a bubble peeling mechanism by vibration.
Instead of performing water flow and air injection from the lower side of the net conveyor 167 of the apparatus shown in FIG. 15, when the bubbles of carbon dioxide gas grow to a certain size, the net conveyor 167 is subjected to shocking vibrations and cleaned and sterilized. By using the effect that sterilizing water penetrates instantly into the space formed by peeling bubbles from the object 131 and moving the volume of the bubbles, the sterilizing water is infiltrated into the cucumber warts to increase the sterilization efficiency. As shown in FIG. 15, stoppers 206 are provided at the lower portions of the jet pipes 16 and the bubble pipes 169 that are alternately arranged. The stoppers 206 on the inner side of the net conveyor 131 collide with the projections 207 at regular intervals to shock the net conveyor. Vibration is generated.

図17は請求項3および5に関する野菜、皿等の食材食器殺菌洗浄方法および請求項16に関する野菜、皿等の食材食器殺菌洗浄装置の具体例について示す。炭酸水生成タンク300(30は図1での使用番号、図9においては第一炭酸生成タンク116や第二炭酸生成タンク116−Aである)は上部より炭酸ガスが供給されるように炭酸ガスボンベ311より手動バルブ及び減圧弁327を介して、炭酸ガスが供給されている。この時の圧力は、ほぼ1センチメートル平方当り3キロ以下で十分である。好ましくは1.5キロ以内が余分なガス化が防げ、しかも送水圧が残り経済効率が良い。単に余分なガス化を防ぐ場合は1キログラム以下の炭酸ガス圧で良い。  FIG. 17 shows a specific example of a sterilizing and cleaning method for food and tableware such as vegetables and dishes according to claims 3 and 5 and an apparatus for sterilizing and cleaning a food and tableware such as vegetables and plates according to claim 16. The carbonated water generation tank 300 (30 is the use number in FIG. 1, and in FIG. 9 is the first carbonate generation tank 116 and the second carbonate generation tank 116-A), so that carbon dioxide gas is supplied from above. Carbon dioxide gas is supplied from 311 through a manual valve and a pressure reducing valve 327. At this time, a pressure of about 3 kg or less per centimeter square is sufficient. Preferably, less than 1.5 km can prevent excessive gasification, and the water pressure remains, resulting in good economic efficiency. To simply prevent excess gasification, a carbon dioxide pressure of 1 kilogram or less is sufficient.

炭酸水生成タンク300内には原水及び食材食器殺菌洗浄装置からポンプ329により管路320及び321を通り323と324に分岐して希釈用の管路306と307から噴射ノズル308により2つの噴射口から激しく衝突して炭酸ガス空間で細かいシャワー上の粒子となって拡散し、炭酸ガスを溶解して所望の炭酸濃度を達成するものである。  In the carbonated water generation tank 300, raw water and food ware sterilizing and washing apparatus is connected to the pipes 320 and 321 by the pump 329 and branched to 323 and 324, and from the pipes 306 and 307 for dilution to the two jet nozzles by the jet nozzle 308. It collides violently and diffuses as fine particles on the shower in the carbon dioxide space, and dissolves the carbon dioxide to achieve the desired carbon dioxide concentration.

この時、HCL水溶液は定量ポンプ314により管路323に圧力供給され、また、アルカリ性の殺菌水溶液NaCLOは定量ポンプ313により管路324に供給されて炭酸水生成タンク300(30は図1での使用番号、図9においては第一炭酸生成タンク116や第二炭酸生成タンク116−Aである)で前記2液の混合と炭酸ガスの吸収がなされた後、減圧弁325を介し供給管路326から連続式食材洗浄殺菌脱臭装置160の循環タンク200に供給される。この時、該循環タンク200の槽内の水位が不足する場合は、これを検知するセンサーから信号を得て、原水が原水供給管310から逆止弁310−Aを通り、制御部(図示せず)からの信号により開閉を制御される電動バルブ309(電磁弁又は、電動ボールバルブ等)で水量を調整しながら給水される。  At this time, the HCL aqueous solution is pressure-supplied to the pipe line 323 by the metering pump 314, and the alkaline sterilizing aqueous solution NaCLO is supplied to the pipe line 324 by the metering pump 313 and the carbonated water generation tank 300 (30 is used in FIG. 1). No., which is the first carbonic acid production tank 116 and the second carbonic acid production tank 116 -A in FIG. 9), after the two liquids are mixed and carbon dioxide is absorbed, from the supply line 326 through the pressure reducing valve 325. It is supplied to the circulation tank 200 of the continuous food cleaning, sterilization and deodorization device 160. At this time, if the water level in the tank of the circulation tank 200 is insufficient, a signal is obtained from a sensor that detects this, and the raw water passes through the check valve 310-A from the raw water supply pipe 310, and the control unit (not shown). Water is supplied while adjusting the amount of water by an electric valve 309 (electromagnetic valve or electric ball valve) whose opening and closing is controlled by a signal from

また、炭酸水生成タンク300(30は図1での使用番号)内の水位は検出管301に配置した水位センサー302、303−A、303−B、303−C、303−D、304、305、により、検出した信号を制御部に電気信号として送って、前記炭酸水生成タンク300内の水位を電動バルブ328(電磁弁又は、電動ボールバルブ等)により制御して行う。さらに、噴射ノズル308のノズル位置とタンク300内の水面高さを、噴射ノズル位置を中心に、水面高さを上下に変動させながら炭酸ガス空間340内の圧力を一定に維持した状態で炭酸ガス濃度を自在に調整できるようになっている。すなわち、噴霧された殺菌水や原水の微小粒子が炭酸ガスと接触する表面積を変更することにより、粒子に吸収される炭酸ガスの濃度を調整できるようになっている。
これにより炭酸水生成タンク300内が高い圧力に維持できるため、排水に高い送水圧力を維持した状態で、炭酸濃度を調整できるように成っている。
Further, the water level in the carbonated water generation tank 300 (30 is the use number in FIG. 1) is the water level sensor 302, 303-A, 303-B, 303-C, 303-D, 304, 305 disposed in the detection tube 301. Thus, the detected signal is sent to the control unit as an electric signal, and the water level in the carbonated water generation tank 300 is controlled by an electric valve 328 (such as an electromagnetic valve or an electric ball valve). Further, the carbon dioxide gas is maintained in a state in which the pressure in the carbon dioxide space 340 is kept constant while the nozzle surface of the injection nozzle 308 and the water surface height in the tank 300 are varied up and down around the injection nozzle position. The density can be adjusted freely. That is, the concentration of carbon dioxide absorbed by the particles can be adjusted by changing the surface area of the sprayed sterilized water or raw water microparticles in contact with the carbon dioxide.
Thereby, since the inside of the carbonated water production tank 300 can be maintained at a high pressure, the carbonate concentration can be adjusted while maintaining a high water supply pressure for the drainage.

さらに詳しく説明すると、炭酸水生成タンク300の水位が噴射ノズル308より下部に位置するように制御すると、激しい噴射衝突によるシャワー状態が炭酸ガス空間で激しい攪拌状態を作り出すため、炭酸ガスの吸収が多く、また、水面が噴射ノズル308より上部に位置するように制御すると、水面の盛り上がり攪拌流が起こるが炭酸ガスと接触する面積がシャワー状の粒子表面積よりも少ないため炭酸ガスの吸収が少ない。  More specifically, when the water level of the carbonated water generation tank 300 is controlled to be located below the injection nozzle 308, the shower state caused by the intense injection collision creates a vigorous stirring state in the carbon dioxide space, so that the absorption of carbon dioxide gas is large. In addition, if the water surface is controlled to be positioned above the injection nozzle 308, the water surface rises and a stirring flow occurs, but the area in contact with the carbon dioxide gas is smaller than the shower-like particle surface area, so that the carbon dioxide gas is less absorbed.

この両者の状態を所定の時間間隔で繰り返すと炭酸ガスの吸収効率を所望の値に制御でき、炭酸水生成タンク300内を高い炭酸ガス圧に維持しても、自由に炭酸ガス濃度を調整することができる。すなわち、例えば、1センチメートル平方当り3キログラムの圧力を掛けても余分な炭酸ガスが気泡となって炭酸水生成タンク300の外に流失しないで、しかも噴射洗浄に必要な送水圧力を保つことができる。
また、図17においては、HCL水溶液とNaCLO水溶液の混合を噴射ノズル308による2液の衝突により行っている。
If both of these states are repeated at predetermined time intervals, the carbon dioxide absorption efficiency can be controlled to a desired value, and the carbon dioxide concentration can be freely adjusted even if the carbonated water generation tank 300 is maintained at a high carbon dioxide pressure. be able to. That is, for example, even when a pressure of 3 kilograms per centimeter square is applied, excess carbon dioxide gas does not flow out of the carbonated water generation tank 300 and keeps the water supply pressure necessary for spray cleaning. it can.
In FIG. 17, the HCL aqueous solution and the NaCLO aqueous solution are mixed by the collision of two liquids by the injection nozzle 308.

図18はHCL水溶液とNaCLO水溶液の混合を管路312において行い、混合後に噴射ノズル308にて炭酸ガス空間340へ衝突噴射する機構を図示したものである。この場合も炭酸ガス空間340内で溶解する炭酸ガスの効率は図17の形態と同等である。  FIG. 18 illustrates a mechanism in which the HCL aqueous solution and the NaCLO aqueous solution are mixed in the pipe 312 and the mixture is mixed and injected into the carbon dioxide gas space 340 by the injection nozzle 308 after mixing. Also in this case, the efficiency of the carbon dioxide dissolved in the carbon dioxide space 340 is equivalent to the form of FIG.

図19は請求項4項に記載した野菜、皿等の食材食器殺菌洗浄方法および請求項15項に記載した野菜、皿等の食材食器殺菌洗浄装置に関する具体例を示す。
炭酸ガスボンベ311から炭酸水生成タンク300の上部に炭酸ガスが供給され、下部より次亜塩素酸ナトリウム溶液が定量ポンプ313により原水流量に比例して原水供給用の管路321に供給され逆止弁330を通り、混合管312に入り数枚の邪魔板331により均一に混合されて噴射ノズル308に在る対抗する2つの噴射口から噴射されてシャワー状の細かい水粒子となり、炭酸ガス空間332に拡散する。
FIG. 19 shows a specific example of the food and tableware sterilizing and cleaning method for vegetables and dishes according to claim 4 and the food and tableware sterilizing and cleaning device for vegetables and dishes according to claim 15.
Carbon dioxide gas is supplied from the carbon dioxide cylinder 311 to the upper part of the carbonated water generation tank 300, and sodium hypochlorite solution is supplied from the lower part to the raw water supply pipe 321 in proportion to the raw water flow rate by the metering pump 313. 330, enters the mixing tube 312, is uniformly mixed by several baffle plates 331, and is sprayed from two opposing spray ports in the spray nozzle 308 to form shower-like fine water particles, into the carbon dioxide space 332. Spread.

また、炭酸水生成タンク300(30は図1での使用番号)内の水位は検出管301に配置した水位センサー302、303−A、303−B、303−C、303−D、304、305、により、検出した信号を制御部に電気信号として送って、前記炭酸水生成タンク300内の水位を電動バルブ328(電磁弁又は、電動ボールバルブ等)により制御して行う。さらに、噴射ノズル308のノズル位置とタンク300内の水面高さを、噴射ノズル位置を中心に、水面高さを上下に変動させながら炭酸ガス空間340内の圧力を一定に維持した状態で炭酸ガス濃度を自在に調整できるようになっている。すなわち、噴霧された殺菌水や原水の微小粒子が炭酸ガスと接触する表面積を変更することにより、粒子に吸収される炭酸ガスの濃度を調整できるようになっている。  Further, the water level in the carbonated water generation tank 300 (30 is the use number in FIG. 1) is the water level sensor 302, 303-A, 303-B, 303-C, 303-D, 304, 305 disposed in the detection tube 301. Thus, the detected signal is sent to the control unit as an electric signal, and the water level in the carbonated water generation tank 300 is controlled by an electric valve 328 (such as an electromagnetic valve or an electric ball valve). Further, the carbon dioxide gas is maintained in a state in which the pressure in the carbon dioxide space 340 is kept constant while the nozzle surface of the injection nozzle 308 and the water surface height in the tank 300 are varied up and down around the injection nozzle position. The density can be adjusted freely. That is, the concentration of carbon dioxide absorbed by the particles can be adjusted by changing the surface area of the sprayed sterilized water or raw water microparticles in contact with the carbon dioxide.

図20についてユニット式炭酸水生成タンク70を示す。炭酸水生成タンク300(30)は配管用の塩化ビニール製の安価な機材で構成され、上下両端は液密に接着された外側にネジ加工が施されたもので上部からは炭酸ガスが供給できるように先端部に管用ネジ加工がある、液面を上下に変化させる調整できる範囲の位置に多数のノズル口339が階層状に多数配置されている。  A unit-type carbonated water generation tank 70 is shown in FIG. The carbonated water generation tank 300 (30) is composed of inexpensive equipment made of vinyl chloride for piping, and the upper and lower ends are liquid-tightly bonded and externally threaded so that carbon dioxide can be supplied from above. In this manner, a large number of nozzle ports 339 are arranged in a hierarchical manner at positions in a range where adjustment is possible to change the liquid level up and down, where there is a threaded tube for the tip.

炭酸水生成タンク300部材の外側にやはり配管用のT型継ぎ手70−Aに第2タンクパイプ307が上下に接着されている。
接着された第2タンクパイプ307の上下両端はシールリング70−1とOリング70−3により炭酸水生成タンク300との間に第2タンク338を形成している。次亜塩素酸ナトリウム水溶液が供給管路321からT型継ぎ手335を介して管路70−2を通り第2タンクに供給され、ノズル口339から圧力噴射される。
The second tank pipe 307 is bonded to the outside of the carbonated water generation tank 300 on the T-type joint 70-A for piping.
The upper and lower ends of the bonded second tank pipe 307 form a second tank 338 between the carbonated water generation tank 300 by a seal ring 70-1 and an O-ring 70-3. A sodium hypochlorite aqueous solution is supplied from the supply line 321 through the T-type joint 335 to the second tank and supplied to the second tank, and is pressure-injected from the nozzle port 339.

該ノズル口339は互いに噴射流が衝突して細かい液粒子に成るように成っている。ノズル口339はノズル自体に噴霧化機能を有する物を使用しても良い。このように構成されたユニット式炭酸水生成タンク70は先端部にあるネジにより、連通管332に接着されたT型配管継ぎ手331に接着されたブッシュ管310の内側ネジと接合されている。さらに、パッキン341で液密に密着させることにより、ユニット式炭酸水生成タンク70が簡単に液密状態を確保できるとともに簡単に着脱ができるように成っている。  The nozzle ports 339 are configured so that the jet flows collide with each other to form fine liquid particles. As the nozzle port 339, a nozzle having a spraying function may be used. The unit type carbonated water generation tank 70 configured as described above is joined to the inner screw of the bush pipe 310 bonded to the T-type pipe joint 331 bonded to the communication pipe 332 by the screw at the tip. Furthermore, the unit-type carbonated water generation tank 70 can be easily secured in a liquid-tight state and can be easily attached / detached by being tightly liquid-tightly attached by the packing 341.

図21及び図22は図20に示す炭酸水生成タンク300のタンク壁に階層状に配置されたノズルの形状を示すノズル断面図である。ノズル339は先端に2つの互いに衝突する噴射流が形成できるように在る角度で交差する噴射口の軸泉を有している。
ノズル341はノズル内部に回転流を生成するリブ341−2を有するコマ部材341−1が在り、先端部に円錐形の形状が先端部に小径の噴射口があり液が回転しながらこの噴射口から霧上に生成されるように成っている、噴射された霧の大きな粒子が外径部分に集まるため、これ等と衝突して粒子を破砕するために櫛状突起341−3が数本用意されている。これ等のノズルが階層状に炭酸水生成タンク300の壁に多数配置してある。
21 and 22 are nozzle cross-sectional views showing the shapes of the nozzles arranged in a hierarchy on the tank wall of the carbonated water generation tank 300 shown in FIG. The nozzle 339 has a jet spring shaft intersecting at an angle so that two mutually colliding jet flows can be formed at the tip.
The nozzle 341 has a top member 341-1 having a rib 341-2 that generates a rotational flow inside the nozzle, and has a conical shape at the tip and a small-diameter jet at the tip. Since the large particles of sprayed mist that are generated on the mist gather at the outer diameter portion, several comb-shaped projections 341-3 are prepared to crush the particles by colliding with them. Has been. A large number of these nozzles are arranged on the wall of the carbonated water generation tank 300 in a hierarchical manner.

図23は、図20に示したユニット式炭酸水生成タンク装置70が下部において並列に連通管332とT型継ぎ手331により連通され、上部からは各々に圧力ホース334を介して、炭酸ガス供給機構70−Bにより所定の圧力が維持されるように炭酸ガスが供給されている多連式炭酸水生成装置200の実施の形態を示す図である。図23にある希釈水は前記原水と同義の意味である。水位検知管301の上部にはエアー抜きバルブ305があり、バルブ305を開いて給水すると、水によりタンク内の空気が炭酸ガス分配管333を介してバルブ305からおいだされるように配置されている。In FIG. 23, the unit-type carbonated water generation tank device 70 shown in FIG. 20 is communicated in parallel at the lower part by a communication pipe 332 and a T-shaped joint 331, and from the upper part via a pressure hose 334, a carbon dioxide gas supply mechanism. It is a figure which shows embodiment of the multiple-type carbonated water production | generation apparatus 200 currently supplied with carbon dioxide gas so that a predetermined pressure may be maintained by 70-B. The dilution water in FIG. 23 has the same meaning as the raw water. There is an air vent valve 305 at the top of the water level detection pipe 301. When the valve 305 is opened and water is supplied, the water in the tank is placed by the water via the carbon dioxide distribution pipe 333 from the valve 305. Yes.

図24においては次亜塩素酸生成時における、殺菌水のpH変化図であり、測定して得た値の折れ線グラフを示す。
黒四角印の折れ線は、次亜塩素酸ナトリウムと重炭酸ナトリウムを含む水溶液に塩酸を混入したときのpH値を示し、▲印は単に次亜塩素酸ナトリウムに塩酸を混入したときのpH値を示す。この実験に使用した各成分は次の通りである。
(1) 水道水 250ml
(2) 次亜塩素酸ナトリウム(濃度12%) 0.4ml
(3) 塩酸(濃度7.2%)
(4) 重炭酸ナトリウム0.3g
において塩酸7.2%液を0.1mlずつ添加してpHの変化を測定した、
In FIG. 24, it is a pH change figure of sterilization water at the time of hypochlorous acid production | generation, and shows the line graph of the value obtained by measuring.
The black square line indicates the pH value when hydrochloric acid is mixed with an aqueous solution containing sodium hypochlorite and sodium bicarbonate, and the ▲ mark simply indicates the pH value when hydrochloric acid is mixed with sodium hypochlorite. Show. Each component used in this experiment is as follows.
(1) Tap water 250ml
(2) Sodium hypochlorite (concentration 12%) 0.4ml
(3) Hydrochloric acid (concentration 7.2%)
(4) Sodium bicarbonate 0.3g
The pH change was measured by adding 0.1 ml of a 7.2% hydrochloric acid solution at a time.

図24は次亜塩素酸ナトリウムに塩酸だけを添加した場合と重炭酸ナトリウムも添加した場合のpH5〜6の間に緩やかな中和曲線が見られる。即ち、塩酸量が増加しても重炭酸ナトリウムと塩酸により炭酸を生成させたタイプは、明らかに、pH値が緩やかに下がっている。このことから、炭酸ガスの溶解から炭酸を生成させる事により、次亜塩素酸水溶液の殺菌水を高い濃度で使用する場合においても安定したpH管理が出来ることを示している。また、これは同時に塩素ガスの発生がない安全な高濃度次亜塩素酸殺菌水の利用を可能にすることを示している。  FIG. 24 shows a mild neutralization curve between pH 5 and 6 when only hydrochloric acid is added to sodium hypochlorite and when sodium bicarbonate is also added. That is, even when the amount of hydrochloric acid is increased, the pH value of the type in which carbonic acid is generated with sodium bicarbonate and hydrochloric acid is gradually lowered. This indicates that by generating carbonic acid from dissolution of carbon dioxide gas, stable pH control can be achieved even when sterilized water of hypochlorous acid aqueous solution is used at a high concentration. This also indicates that it is possible to use safe high-concentration hypochlorous acid sterilizing water without generation of chlorine gas.

(1) 水道水 240ml
(2) 次亜塩素酸ナトリウム(濃度12%) 10ml
(3) 塩酸(濃度7.6%)
(4) 重炭酸ナトリウム0.3g
において塩酸7.6%液を1mlずつ添加してpHの変化を測定した、
FIG. 25 is a pH change diagram of sterilized water at 4800 ppm sodium hypochlorite during hypochlorous acid production, and shows a line graph of values obtained by measurement. The black square line indicates the pH value when hydrochloric acid is mixed in an aqueous solution containing sodium hypochlorite and sodium bicarbonate, and the ▲ mark simply indicates the pH when hydrochloric acid is mixed with sodium hypochlorite. Indicates the value. Each component used in this experiment is as follows.
(1) Tap water 240ml
(2) Sodium hypochlorite (concentration 12%) 10ml
(3) Hydrochloric acid (concentration 7.6%)
(4) Sodium bicarbonate 0.3g
In 1 ml of hydrochloric acid 7.6% solution was added to measure the change in pH.

図25からも判るように、次亜塩素酸ナトリウム濃度が約4800ppmの濃度においても明らかにpH7近辺からpH4位まで緩衝効果が識別できる。  As can be seen from FIG. 25, even at a sodium hypochlorite concentration of about 4800 ppm, the buffering effect can be clearly distinguished from around pH 7 to pH 4.

炭酸水による洗浄は、高濃度炭酸水が安価で簡単に、しかも、副生成物を生じないで連続生成出来る技術が、なかったため、食品業界には、全く使われず、その特徴が利用されなかった。また、殺菌水が使用される現場は食品工場が多く、本機械から炭酸水だけを別に取り出し、食品製造のさまざまな分野に利用することも出来る。  Washing with carbonated water was not used at all in the food industry, and its characteristics were not used because there was no technology that could produce high-concentration carbonated water cheaply and easily without producing by-products. . In addition, there are many food factories where sterilized water is used, and it is possible to take out only carbonated water separately from this machine and use it in various fields of food production.

例えば、洗浄水や浸漬水として利用する場合、高濃度の炭酸水はpHが6〜5と酸性になるため、アルカリ洗浄の欠点でも在る、旨みの溶出がない。食品の洗浄において、旨味を溶出させないので、製造ラインなどにおいても、洗浄用や浸漬水(戻し用の水)として、広く利用されるようになると考える。また、食品ばかりでなく、医療においては洗浄と殺菌は同時に、要求される課題であり、しかも、炭酸水のpH6〜5の範囲に極めて安定したpH緩衝作用があるため、次亜塩素酸の安全でしかも安定的効果が得られる使用が可能である。  For example, when used as washing water or immersion water, since high-concentration carbonated water becomes acidic with a pH of 6 to 5, there is no leaching of umami, which is also a drawback of alkaline washing. Since umami is not eluted in the washing of food, it is considered that it will be widely used as a washing or immersion water (return water) in production lines. In addition to food, cleaning and sterilization are simultaneously required issues in medicine, and since there is a very stable pH buffering action in the pH 6-5 range of carbonated water, the safety of hypochlorous acid Moreover, it can be used to obtain a stable effect.

また、次亜塩素酸の有効なpH領域と炭酸のpH緩衝領域が重なっており、次亜塩素酸の最大酸化有効範囲が維持しやすくなる。医療分野では殺菌が重要な課題で在り、この利用を発展させる上で、次亜塩素酸殺菌水に炭酸ガス含有水あるいは炭酸ガスを注入して使用することは、極めて有効な技術であり、次亜塩素酸の利用範囲が、さまざまな医療分野にも拡大するものと考えている。又、エステ美容のような美容の分野にも、拡大するものと考えている。  Moreover, the effective pH range of hypochlorous acid and the pH buffering range of carbonic acid overlap, and it becomes easy to maintain the maximum oxidation effective range of hypochlorous acid. Sterilization is an important issue in the medical field, and in developing this use, the use of carbon dioxide containing water or carbon dioxide in hypochlorous acid sterilized water is an extremely effective technology. We believe that the range of use of chlorous acid will be extended to various medical fields. It is also expected to expand into the field of beauty such as beauty treatment.
