Description

本発明は、野菜の洗浄方法に関する。   The present invention relates to a method for washing vegetables.

従来の溶存オゾン濃度測定は、オゾン水生成器内で生成された流中のオゾン水を、生成器近傍に付設された濃度計にておこなっていた。また、洗浄槽等に貯えられたオゾン水は、被測定水のサンプルを採取して測定可能器具が設置された所定の場所で測定をおこなっていた。
よって、オゾン水を洗浄槽に貯えて野菜を洗浄する現場では、生成器からの生成オゾン水の濃度管理はおこなえるが、使用中の洗浄槽内のオゾン水の溶存オゾン濃度の変化は読み取れなかった。つまり、溶存オゾン濃度による洗浄効果の状態は読み取らず、野菜を浸した時間にて洗浄効果を判断していた。（特許文献１参照） Conventional dissolved ozone concentration measurement has been performed by using a concentration meter attached to the vicinity of the generator for ozone water in the flow generated in the ozone water generator. In addition, ozone water stored in a washing tank or the like was measured at a predetermined place where a sample of water to be measured was collected and a measurable instrument was installed.
Therefore, at the site where the ozone water is stored in the washing tank and the vegetables are washed, the concentration of the generated ozone water from the generator can be controlled, but the change in the dissolved ozone concentration of the ozone water in the washing tank in use could not be read. . That is, the state of the cleaning effect due to the dissolved ozone concentration was not read, and the cleaning effect was determined by the time when the vegetables were soaked. (See Patent Document 1)

つまり、現場での使用中のオゾン水の溶存オゾン濃度測定ができず、生成器に近傍に付設された濃度計に表示された生成時の濃度表示を信じるしかないという欠点があった。
さらに、従来の野菜の洗浄方法は同種同量の生産の現場では、実績データから時間管理での洗浄効果が信頼できるが、多種類の生産では実積データを取るには手間と時間がかかり、野菜をオゾン水に浸漬させた時間にて洗浄効果を信じるしかないという欠点があった。
特開２００６−３３３７３２号公報 In other words, the dissolved ozone concentration of ozone water in use at the site could not be measured, and there was a drawback that the concentration display at the time of generation displayed on the concentration meter attached to the generator could only be believed.
In addition, the conventional vegetable washing method is reliable in the time management from the actual data at the same kind and the same amount of production site, but it takes time and effort to obtain the actual product data in many kinds of production, There was a drawback that the cleaning effect could only be believed by the time when the vegetables were immersed in ozone water.

上述した溶存オゾン濃度計15の使用方法と作用について説明する。
まず、被測定水21のある現場に溶存オゾン濃度計15を携帯し、溶存オゾン濃度計15の被測定水吸水口11にホース17の一方を接続し、ホース17の他方を被測定水（オゾン水）21に浸す。次に、原水吸水口10にホース16の一方を接続し、ホース16の他方を原水20に浸す。また、排水口12にホース18の一方を接続し、他方を排水処理容器33に向ける。そして、溶存オゾン濃度計15の表面１ｂにある電源スイッチ30を入れた後、ポンプスイッチ31を入れる。すると、ケーシング１内の切換弁９は原水吸水路26と測定路29を開通させると共に、被測定水吸水路27は切換弁９にて止まり配管となる。つまり、ポンプ４が起動すると、原水20が測定路29を流れ、さらに、透明筒部５を通過して、ポンプ４を通り排出口12から排出される。このとき、透明筒部５を通過する原水20に紫外線ランプ６を照射させて、原水20を通過した光線を受光部にて受け、測定データを演算部にて記憶する。即ち、原水20を紫外線吸光方式によって測定している。そして、所定の時間が経過すると、切換弁９が自動切換し、被測定水吸水路27と測定路29を開通させると共に、原水吸水路26は止まり配管となる。よって、被測定水（オゾン水）21がポンプ４によって透明筒部５を通過し、紫外線吸光方式によって測定された後、排水口12から排出される。そして、原水20の測定データを基に被測定水21の測定データの校正や計算が演算部８にておこなわれ、被測定水（オゾン水）21の濃度を算出し、出力信号にて表示部３に伝送され、測定結果がデジタル表示される。 The use method and operation of the above-described dissolved ozone concentration meter 15 will be described.
First, the dissolved ozone concentration meter 15 is carried to the site where the measured water 21 is located, one end of the hose 17 is connected to the measured water inlet 11 of the dissolved ozone concentration meter 15, and the other end of the hose 17 is connected to the measured water (ozone Immerse in water 21. Next, one end of the hose 16 is connected to the raw water inlet 10, and the other end of the hose 16 is immersed in the raw water 20. Further, one end of the hose 18 is connected to the drain port 12 and the other is directed to the waste water treatment container 33. Then, after turning on the power switch 30 on the surface 1b of the dissolved ozone concentration meter 15, the pump switch 31 is turned on. Then, the switching valve 9 in the casing 1 opens the raw water absorption path 26 and the measurement path 29, and the measured water absorption path 27 stops at the switching valve 9 and becomes a pipe. That is, when the pump 4 is activated, the raw water 20 flows through the measurement path 29, passes through the transparent cylinder portion 5, passes through the pump 4, and is discharged from the discharge port 12. At this time, the raw water 20 passing through the transparent tube portion 5 is irradiated with the ultraviolet lamp 6, the light beam passing through the raw water 20 is received by the light receiving portion, and the measurement data is stored in the calculation portion. That is, the raw water 20 is measured by the ultraviolet absorption method. When a predetermined time elapses, the switching valve 9 is automatically switched to open the measured water absorption path 27 and the measurement path 29, and the raw water absorption path 26 becomes a stop pipe. Therefore, the water to be measured (ozone water) 21 passes through the transparent tube portion 5 by the pump 4 and is measured by the ultraviolet absorption method and then discharged from the drain port 12. Then, calibration and calculation of measurement data of the sample water 21 is performed by the arithmetic unit 8 based on the measurement data of the raw water 20, to calculate the concentration of the sample water (ozone water) 21, a display unit by the output signal 3 and the measurement result is digitally displayed.

次に、野菜の洗浄方法の作用について説明する。
まず、給水口22を開き、生成器24と、溶存オゾン濃度計15と、に原水20を供給する。そして、生成器24に供給された原水20をオゾン水に生成して、補給路23から洗浄槽25に貯水する。次に、溶存オゾン濃度計15の電源スイッチ30とポンプスイッチ31をＯＮにして、原水20と貯水されたオゾン水である被測定水21の測定を開始する。また、測定された、原水20又は被測定水21は、排水として溶存オゾン濃度計15の排水口12に接続されたホース18によって排水溝に流出させる。次に、オゾン水である被測定水21が貯水された洗浄槽25に洗浄される野菜を投入する。投入後、野菜はオゾン水である被測定水21中の溶存オゾンの酸化反応よって、洗浄（殺菌・脱臭）され、洗浄槽25内の被測定水21中の溶存オゾン濃度を測定中の溶存オゾン濃度計15が後述する濃度による判断基準をもとに野菜の洗浄の終了を判断して信号を出力し、生成器24を停止させると共に、作業者にランプを点灯させて知らせる。 Next, the effect | action of the washing | cleaning method of vegetables is demonstrated.
First, the water supply port 22 is opened, and the raw water 20 is supplied to the generator 24 and the dissolved ozone concentration meter 15. Then, the raw water 20 supplied to the generator 24 is generated into ozone water and stored in the cleaning tank 25 from the replenishment path 23. Next, the power switch 30 and the pump switch 31 of the dissolved ozone concentration meter 15 are turned ON, and measurement of the raw water 20 and the measured water 21 that is the stored ozone water is started. In addition, the measured raw water 20 or measured water 21 is discharged as drainage into the drainage channel by the hose 18 connected to the drainage port 12 of the dissolved ozone concentration meter 15. Next, the vegetables to be washed are put into the washing tank 25 in which the measured water 21 which is ozone water is stored. After the input, the vegetables are washed (sterilized and deodorized) by the oxidation reaction of the dissolved ozone in the measured water 21 which is ozone water, and the dissolved ozone in which the dissolved ozone concentration in the measured water 21 in the cleaning tank 25 is being measured. The densitometer 15 determines the end of vegetable washing based on a determination criterion based on the concentration described later, outputs a signal, stops the generator 24, and informs the operator by lighting the lamp.

ここで、上述の洗浄中の洗浄槽25内の被測定水21中の溶存オゾン濃度は、溶存オゾン（Ｏ3 ）が酸素（Ｏ2 ）と酸素原子となり、酸素原子が細菌の細胞膜に作用し酸化することで殺菌し、また、溶存オゾン（Ｏ3 ）が例えばアンモニア（ＮＨ3 ）と反応して窒素（Ｎ2 ）と水（Ｈ2 Ｏ）になることで、脱臭するので、低下している。つまり、洗浄槽25内の被測定水21中の溶存オゾン濃度は野菜を洗浄（殺菌・脱臭）すると低下し、オゾンの酸化反応による殺菌・脱臭が終了すると、生成器24からオゾン水を常に補給しているので上昇するといった、溶存オゾン濃度の濃度変化が起きている。
即ち、図５に示す溶存オゾン濃度計15の測定結果である濃度を縦軸Ｐとして、時間の経過を横軸ｔとした、グラフ図にて説明すると、洗浄槽25内の被測定水21の野菜投入前の溶存オゾン濃度はＳ値で略一定であり、洗浄層25内に野菜を投入した時期Ａから、上述した化学反応により、溶存オゾン濃度はＲまで低下する。そして溶存オゾンによる野菜の洗浄が終了すると溶存オゾン濃度は、上昇し、再びＳ値で略一定となる。
つまり、溶存オゾン濃度計15が野菜の洗浄の終了を判断する基準を、洗浄槽25内の被測定水21中の溶存オゾン濃度がＳ値の40％〜80％とする所定のＴ値であり、かつ、測定開始から最初の低下中のＴ値ではなく次の上昇中のＴ値を読み取った時、と定義し、信号を出力するように、溶存オゾン濃度計15の演算部８にプログラミングすることで、溶存オゾン濃度計15が洗浄完了を判断し、生成器24を停止させると共に、ランプ32の点灯によって作業者に伝えている。 Here, the dissolved ozone concentration in the water 21 to be measured in the washing tank 25 during the washing is that the dissolved ozone (O 3 ) becomes oxygen (O 2 ) and oxygen atoms, and the oxygen atoms act on the bacterial cell membrane. It is sterilized by oxidation, and dissolved ozone (O 3 ) reacts with, for example, ammonia (NH 3 ) to become nitrogen (N 2 ) and water (H 2 O), thereby deodorizing, so it decreases. Yes. In other words, the dissolved ozone concentration in the water to be measured 21 in the washing tank 25 decreases when the vegetables are washed (sterilized / deodorized), and after the sterilization / deodorization by the oxidation reaction of ozone is completed, ozone water is always supplied from the generator 24. The concentration change of the dissolved ozone concentration, such as rising, has occurred.
That is, when the concentration as the measurement result of the dissolved ozone densitometer 15 shown in FIG. 5 is plotted on the vertical axis P and the passage of time is plotted on the horizontal axis t, the graph shows the measured water 21 in the washing tank 25. The dissolved ozone concentration before the addition of vegetables is substantially constant as the S value, and the dissolved ozone concentration decreases to R due to the above-described chemical reaction from the time A when the vegetables are introduced into the cleaning layer 25. And when washing | cleaning of the vegetable by dissolved ozone is complete | finished, dissolved ozone concentration will rise and it will become substantially constant again by S value.
In other words, the standard for the dissolved ozone concentration meter 15 to judge the end of washing of vegetables is a predetermined T value in which the dissolved ozone concentration in the measured water 21 in the washing tank 25 is 40% to 80% of the S value. And, when the T value during the next rise is read instead of the first T value during the decline from the start of measurement, it is defined as being programmed, and the arithmetic unit 8 of the dissolved ozone concentration meter 15 is programmed to output a signal. Thus, the dissolved ozone concentration meter 15 determines the completion of cleaning, stops the generator 24, and notifies the operator by lighting the lamp 32.

溶存オゾン濃度計は、取手２を有する携帯自在なケーシング１と、このケーシング１の内部に設けられたポンプ４と、測定用の透明筒部５と、紫外線ランプ６と、受光部７と、予め入力した演算式に従って受光線量をオゾン含有量に演算する演算部８と、を具備し、さらに被測定水21と、原水20とを切換える切換弁９と、オゾン濃度を演算部８からの出力信号によってデジタル表示する表示部３とを具備しているので、携帯可能で、使用中のオゾン水（被測定水21）の溶存オゾン濃度を測定でき、現場での溶存オゾン濃度管理が迅速かつ容易におこなえる。また、一台で複数の洗浄槽25を測定して回れるので、経済的である。また、ポンプ４を内蔵しているので、溜水状態のオゾン水（被測定水）の測定を容易におこなえる。また、原水20と生成されたオゾン水（被測定水21）を測定し、原水20の測定値とオゾン水（被測定水21）の測定値を比較校正できるので、オゾン水生成器24の信頼性や性能評価を原水20の成分に影響されることなく正確におこなえる。また、デジタル表示することで、測定値が一目瞭然でデータ読取の個人差を軽減し、より正確なデータ収集ができる。また、実際に生成された濃度を調べることで、オゾン水生成器の生成設定濃度と比較して、オゾン水生成器24の点検や保守が容易におこなえる検査器具としても使用できる。また、切換弁９にて原水20と被測定水21の取水経路を切り換えることができるので、原水20と被測定水21に各々原水吸水ホース16と被測定水吸水ホース17を設置すれば、ホース16，17の付け替えや原水20や被測定水21の入れ換えをおこなう必要がなく、測定中に手間がかからず、迅速に測定できる。複数（多数）の現場に順次携帯して、使用中のオゾン水（被測定水）の溶存オゾン濃度を測定できる。このように複数（多数）現場での溶存オゾン濃度管理が迅速かつ容易におこなえる。   The dissolved ozone concentration meter includes a portable casing 1 having a handle 2, a pump 4 provided inside the casing 1, a transparent tube portion 5 for measurement, an ultraviolet lamp 6, a light receiving portion 7, A calculation unit 8 that calculates the received light dose to the ozone content according to the input calculation formula, a switching valve 9 that switches between measured water 21 and raw water 20, and an output signal from the calculation unit 8 for the ozone concentration. Since it is equipped with the display unit 3 for digital display, it is portable and can measure the dissolved ozone concentration of the ozone water (measured water 21) in use, so that the dissolved ozone concentration can be managed quickly and easily on site. You can do it. Moreover, since a plurality of washing tanks 25 can be measured and rotated with one unit, it is economical. In addition, since the pump 4 is built in, it is possible to easily measure the ozone water (measured water) in the accumulated water state. In addition, since the raw water 20 and the generated ozone water (measured water 21) can be measured and the measured values of the raw water 20 and ozone water (measured water 21) can be compared and calibrated, the reliability of the ozone water generator 24 can be measured. The performance and performance can be accurately evaluated without being affected by the components of the raw water 20. In addition, the digital display allows the measurement values to be seen at a glance, reduces individual differences in data reading, and enables more accurate data collection. In addition, by examining the actually generated concentration, it can be used as an inspection instrument that can easily check and maintain the ozone water generator 24 as compared to the generation set concentration of the ozone water generator. In addition, since the intake path of the raw water 20 and the measured water 21 can be switched by the switching valve 9, if the raw water absorption hose 16 and the measured water absorption hose 17 are installed in the raw water 20 and the measured water 21, respectively, the hose It is not necessary to replace 16 and 17 or to replace the raw water 20 or the water 21 to be measured. It can be carried sequentially to multiple (many) sites to measure the dissolved ozone concentration of the ozone water (measurement water) in use. In this way, the dissolved ozone concentration can be quickly and easily managed at multiple (many) sites.

以上のように、本発明に係る野菜の洗浄方法は、洗浄槽25内の被測定水21を吸込み、野菜の投入前から投入後にわたって、溶存オゾン濃度計15によって継続的にオゾン濃度を測定しつつ、野菜をオゾン洗浄し、オゾン濃度が、一旦低下した後に、上昇して、元の40％〜80％の設定値に達すれば、洗浄を完了するので、確実に洗浄効果を得られたことが確認できる。また、野菜の形状や大きさや汚れ具合などの被洗浄物の条件が多種であっても野菜が確実に洗浄できる。また、野菜をオゾン水に無駄な時間浸漬させることがないので、洗浄時間の減少によるコスト削減ができ経済的である。また、洗浄が終了しているのに、オゾン水を必要以上に洗浄槽25に供給する必要がなくなり経済的である。また、様々な大きさや形状の野菜同士の組合せにも迅速に対応できるので、設備の多用化が計れる。また、オゾン水である被測定水21だけでなく、原水20を測定できるので、原水20の測定データによる校正がおこなえ、原水20の成分に影響されることのない正確な被測定水21の溶存オゾン濃度によって、野菜の洗浄完了を判断できる。また、溶存オゾン濃度で洗浄状況を判断できるので、浸積時間による洗浄効果の実績データがないものでも確実に洗浄できる。   As described above, the vegetable washing method according to the present invention sucks the water to be measured 21 in the washing tank 25 and continuously measures the ozone concentration with the dissolved ozone concentration meter 15 before and after the vegetable is charged. On the other hand, the vegetables were washed with ozone, and once the ozone concentration dropped and then increased, and reached the original set value of 40% to 80%, the washing was completed, so the washing effect was reliably obtained Can be confirmed. Moreover, even if there are various conditions for the object to be cleaned such as the shape and size of the vegetable and the degree of dirt, the vegetable can be reliably washed. Moreover, since vegetables are not immersed in ozone water for a useless time, the cost can be reduced by reducing the washing time, which is economical. Moreover, it is economical because it is not necessary to supply ozone water to the cleaning tank 25 more than necessary even though the cleaning is completed. Moreover, since it can respond quickly to the combination of vegetables of various sizes and shapes, the equipment can be diversified. In addition, since the raw water 20 can be measured as well as the measured water 21 that is ozone water, calibration based on the measurement data of the raw water 20 can be performed, and the accurate dissolution of the measured water 21 without being affected by the components of the raw water 20 The completion of washing of vegetables can be judged by the ozone concentration. In addition, since the cleaning status can be determined based on the dissolved ozone concentration, it is possible to reliably clean even those for which there is no actual cleaning effect data based on the immersion time.
