Description

【0001】
[発明の属する技術分野]
本発明は農水産業あるいは農水産加工分野における鮮度保持技術の改良に関するものである。つまり、農水産物およびその加工品は冷却と殺菌を同時に行うことによって、処理時間が短縮されそれだけ鮮度の改善に効果があらわれるのである。
【0002】
[従来の技術]
従来シャーベット氷に殺菌作用を持たせる方法として、海水または塩水にオゾン(O)を溶解させ、これを原水としてシャーベット氷を生成する方法があった。
【0003】
図2は従来一般に用いられているオゾン水によるシャーベット氷の製造システムの例である。15はオゾン発生装置、16は気液分離機、17は排オゾン分解器、18は海水または塩水、19はオゾンを水に溶解させるエジェクター、8は取水ポンプ、9はシャーベット氷タンク、11は製氷機、12は冷媒、13は冷凍機、10は循環ポンプ、14は膨張弁、20はオゾンを溶解した海水または塩水でできた原水である。
【0004】
次に、図2により動作について説明する。オゾンガス発生器15で生成されたオゾンはエジェクター19で海水または塩水に溶解されるが、不溶解分は気液分離機16でオゾン水から分離された後、排オゾン分解器17より放出される。不溶解分を分離したオゾン水は氷タンク9に送られシャーベット氷の原水20となって循環ポンプ10により製氷機11に送られる。一方、冷凍機13から送られてきた冷媒12は膨張弁14にて減圧されて製氷機11に送られ、ここで原水より熱を奪って蒸発する。原水の温度が概ね−2℃以下になると製氷機でシャーベット氷が生成されて氷タンク9に送られ貯蔵される。こうして氷タンク9には時間の経過とともに氷の割合が増えていく。
【0005】
【発明が解決しようとする課題】
オゾンを溶解させた海水または塩水をシャーベット氷の原水として使用する場合、
(1)海水または塩水に溶解したオゾンは、水温にもよるが、数十分から数時
間以内に分解して酸素になってしまい殺菌作用を失うこと。
(2)オゾンは海水中のヨウ素と化合して有毒成分であるオキシダントを生成
するために原水段階での除去が必要であること。
(3)オゾンは一般に耐蝕性材料として使用されるFRP材との相性が悪くコ
ストの高いステンレス等を使わざるを得ないこと。
等の課題があった。
【0006】
【問題を解決するための手段】
本発明は上記のような問題点を解消するためになされたもので、オゾンに代えて0.1〜0.2%程度の食塩水を電気分解して得られる次亜塩素酸水またはその希釈水に、塩分を加えた塩水を原水としたシャーベット氷を得るようにした。
【0007】
次亜塩素酸水およびその希釈水には殺菌能力のある塩素ガスを5ppmから30ppmを含んでいる。これに用途によって塩分濃度が2%から8%になるように塩化ナトリウムを加えて塩水をつくり、この塩水を原水としてシャーベット氷を作れば、従来の問題点を解消できる。
【0008】
【発明の実施の形態】
以下、この発明の1実施例を図に基づいて説明する。
図1は本発明によるによるシャーベット氷製氷システムを示す。1は電解水生成装置、2は水道水、3はNacl(塩)、4は次亜塩素酸水、5は塩水タンク、6は塩分量調整弁、7は原水で塩分濃度2%〜8%の次亜塩素酸水またはその希釈水、その他は図1で説明したのと同じであるから説明を省略する。
【0009】
次に動作について説明する。水道水2にNacl(塩)3を入れて塩分濃度が0.1〜0.2%程度になった電解水を電解水生成装置1で電気分解する。電気分解することによって酸性水とアルカリ水が生じるが、この酸性水には次亜塩素酸が50ppmほど含まれている。この次亜塩素酸水4に塩水タンク5から塩分量調整弁6を介して塩分と混入して氷タンク9に注入する。氷タンク9には前もって取水ポンプ8により水道水2が貯められており、ここで塩分濃度が2%から8%の希釈した次亜塩素酸水が作られる。これがシャーベット氷の原水7となる。原水7は循環ポンプ10により製氷機11に送られ、循環冷却されてシャーベット氷を生成し、次第に氷の割合を増やしていく。
【0010】
【発明の効果】
本発明による効果は
(1)次亜塩素酸水およびその希釈水により生成されたシャーベット氷の殺菌力は数週間の単位で効力がある。
(2)次亜塩素酸水およびその希釈水を海水に混ぜた場合でも有毒なオキシダントを発生せず、除去の必要がなく設備コストの低減が可能である。
(3)安価な耐触性材料であるFRP材との相性が良いので、高価なステンレス等の材料を使う必要が無く設備コストの低減が可能である。
ことが効果としてあげられる。

[Technical field to which the invention belongs]
The present invention relates to an improvement in a technique for maintaining freshness in the agricultural and fishery industry or the agricultural and fishery processing field. In other words, by simultaneously cooling and sterilizing agricultural and marine products and their processed products, the processing time is shortened, and the effect of improving freshness is accordingly brought about.
[0002]
[Conventional technology]
Conventionally, as a method for imparting a bactericidal action to sherbet ice, there has been a method in which ozone (O 3 ) is dissolved in seawater or salt water, and this is used as raw water to produce sherbet ice.
[0003]
FIG. 2 shows an example of a conventional system for producing sherbet ice using ozone water. Reference numeral 15 denotes an ozone generator, 16 denotes a gas-liquid separator, 17 denotes a waste ozone decomposer, 18 denotes seawater or salt water, 19 denotes an ejector for dissolving ozone in water, 8 denotes a water intake pump, 9 denotes a sherbet ice tank, and 11 denotes ice making. , A refrigerant, 13 a refrigerator, 10 a circulation pump, 14 an expansion valve, and 20 a raw water made of ozone-dissolved seawater or salt water.
[0004]
Next, the operation will be described with reference to FIG. The ozone generated by the ozone gas generator 15 is dissolved in seawater or salt water by the ejector 19, but the insoluble matter is separated from the ozone water by the gas-liquid separator 16 and then released from the waste ozone decomposer 17. The ozone water from which the undissolved components have been separated is sent to the ice tank 9 and becomes raw water 20 of sherbet ice to be sent to the ice maker 11 by the circulation pump 10. On the other hand, the refrigerant 12 sent from the refrigerator 13 is decompressed by the expansion valve 14 and sent to the ice maker 11, where it takes heat from raw water and evaporates. When the temperature of the raw water falls to about -2 ° C. or less, sherbet ice is generated by an ice machine and sent to an ice tank 9 for storage. Thus, the proportion of ice in the ice tank 9 increases over time.
[0005]
[Problems to be solved by the invention]
When using seawater or saltwater with dissolved ozone as raw water for sherbet ice,
(1) Ozone dissolved in seawater or salt water is decomposed into oxygen within tens of minutes to several hours, depending on the water temperature, and loses its sterilizing effect.
(2) Ozone must be removed at the raw water stage in order to combine with iodine in seawater to form oxidants, which are toxic components.
(3) Ozone is incompatible with the FRP material generally used as a corrosion-resistant material and must use expensive stainless steel or the like.
There were issues such as.
[0006]
[Means to solve the problem]
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has been made to solve the above-mentioned problem. Sherbet ice was obtained by using salt water obtained by adding salt to water as raw water.
[0007]
Hypochlorous acid water and its dilution water contain 5 to 30 ppm of chlorine gas having a sterilizing ability. The conventional problem can be solved by adding sodium chloride so that the salt concentration becomes 2% to 8% depending on the application to form salt water, and making the sherbet ice using the salt water as raw water.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a sherbet ice making system according to the present invention. 1 is an electrolyzed water generator, 2 is tap water, 3 is NaCl (salt), 4 is hypochlorous acid water, 5 is a salt water tank, 6 is a salt amount control valve, 7 is raw water and salt concentration is 2% to 8%. The hypochlorous acid solution or its dilution water is the same as that described with reference to FIG.
[0009]
Next, the operation will be described. NaCl (salt) 3 is added to tap water 2, and electrolyzed water having a salt concentration of about 0.1 to 0.2% is electrolyzed by the electrolyzed water generator 1. Electrolysis produces acidic water and alkaline water, and this acidic water contains about 50 ppm of hypochlorous acid. The hypochlorous acid water 4 is mixed with salt from a salt water tank 5 via a salt amount adjusting valve 6 and injected into an ice tank 9. The tap water 2 is previously stored in the ice tank 9 by the water intake pump 8, and a diluted hypochlorous acid solution having a salt concentration of 2% to 8% is produced therein. This becomes raw water 7 of sherbet ice. The raw water 7 is sent to an ice machine 11 by a circulation pump 10 and is circulated and cooled to produce sherbet ice, and the proportion of ice is gradually increased.
[0010]
【The invention's effect】
The effects of the present invention are as follows: (1) The bactericidal activity of sherbet ice produced by hypochlorous acid water and its dilution water is effective in a unit of several weeks.
(2) Even when hypochlorous acid water and its dilution water are mixed with seawater, toxic oxidants are not generated, and there is no need to remove them, so that equipment costs can be reduced.
(3) Since it is compatible with the inexpensive FRP material which is a touch-resistant material, there is no need to use expensive materials such as stainless steel, and the equipment cost can be reduced.
The effect is as follows.
