2. Description of the Related Art It has been known that acidic ionized water has various effects. In addition, various examples have already existed for producing acidic ionized water by electrolysis and for producing electrolytic acidic ionized water and its apparatus.
However, it is still not possible to generate electrolytic acidic ionized water without adding sodium chloride to tap water, and to automatically freeze electrolytic acidic ionized water generated from additive-free tap water for industrial use. At present, the clear utility and recognition are not well understood, and the technology has not been established.

It is known that acidic ionized water has a bactericidal action, and in addition to being actually used as face-washing water, it is also used for sterilizing and cleaning poultry houses and the like. , Its uses are expected to be further developed in the future.

[0004] As one field of utilizing electrolytic acid ionized water, researches are being conducted on a method of using electrolytic acid ionized water in a frozen state. Among these are the transportation of fresh fish and meat and the maintenance of freshness. Traditionally, ice has been used to transport fresh fish and maintain its freshness. As for this ice, we examined the industrial potential and utility of using acid ion ice in place of frozen ice in the conventional fresh water. As a result, although the freshness of fresh fish meat was not much different from that of conventional ice, the fact that the bactericidal action could be sustained was highly evaluated. However, it was revealed that when sodium chloride (salt) was added to tap water during electrolysis, there was no change in the ice state, but chlorine gas was generated after melting. In addition, mixing salt may cause discoloration or odor (odor of chlorine),
Furthermore, there was concern that the taste of the water itself would deteriorate. Further, since there is no apparatus for producing electrolytically acidic ionized ice on an industrial scale, it would be costly and economically unusable to freeze the produced electrolytically acidic ionized water again in large quantities.

[0008]

The method and apparatus for producing electrolyzed acidic ion ice and electrolyzed acidic water according to the present invention include a method for producing acidic ionized water by electrolyzing tap water, a method for extracting the acidic ionized water and making ice. , And an apparatus that integrally achieves these steps. First, tap water (city water) used in ordinary households is introduced into a water storage tank and retained therein, and then introduced into an electrolysis electrolytic cell equipped with an anode and a cathode. Since ordinary tap water is not suitable for electrolysis, sodium chloride (salt) is generally added to accelerate the reaction, but in the present invention, an electrolytic cell is used instead of the addition of an additive. Tap water is allowed to stand still for a certain period of time in the room. By interposing this step, the electrolytic reaction is promoted even without sodium chloride (salt). In the electrolysis step, when a voltage is applied to both electrodes, acidic water (acidic ion water) is gradually generated on the anode side, and alkaline water is gradually generated on the cathode side. The acidic ionized water thus produced is introduced from the lower part of the electrolytic cell into the ice making machine by opening the valve. Further, a method of introducing acidic water into the ice making machine by separating and collecting acidic water from the lower part of the electrolytic cell by gravity flow is also considered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The method and apparatus for producing electrolyzed acidic ion ice and electrolyzed acidic water according to the present invention will be described in detail below with reference to an embodiment shown in the drawings. FIG. 1 is a schematic view of an electrolytic acidic ion ice producing apparatus as one embodiment embodying the method for producing electrolytic acidic ion ice and electrolytic acidic water according to the present invention, and an electrolytic acidic water producing apparatus inherent in the process. A method for producing electrolytic acidic ion ice, a method for producing electrolytic acidic water, and an apparatus 1 embodying the method include a water storage tank 10, a valve (valve) 20, an electrolytic tank 30, and an ice making device 40.

The water storage tank 10 is a water tank for introducing and storing tap water (city water) 2 used as raw water. The shape of the water tank does not matter, but it is necessary to have a capacity to store a certain amount of tap water. Since tap water 2 is difficult to pass electricity, sodium chloride (salt) is usually added to make it easy to pass electricity, but as stated in the drawbacks of the prior art, it is necessary to use ice for keeping fresh fish in a frozen state. Therefore, since there is a problem of odor and discoloration after dissolution, sodium chloride (salt) is not added in the present invention. Therefore, the water is kept stationary in the electrolytic cell for adjustment.

The valve 20 supplies the city water (tap water) to the water storage tank by opening and closing the valve for transferring the raw water of the water storage tank to the electrolysis tank 30. The supplied city water (tap water) is stored for a required time, then flows down by opening the valve and is transferred to the electrolytic cell. By this step, tap water is introduced into the electrolytic cell 30 having the anode and the cathode, but the electrolytic acidic ion ice manufacturing method according to the present invention can be carried out without the water tank. That is, it is possible to directly control tap water and intermittently introduce it into the electrolytic cell. In this embodiment, the system is a flow-down system, and tap water is intermittently supplied in relation to the reaction efficiency of electrolysis as described later. Therefore, the operation of the valve is controlled by the control device 22 having a built-in timer or the like so as to intermittently supply water.

As the electrolytic cell 30, various ones shown in the above-mentioned known examples can be used, but the electrolytic cell used in this embodiment is a conventional one having an anode 32 and a cathode 34 which are conventionally used. It is an electrolytic cell. Structurally, any electrolyzer may be used, and an electrolyzing step for separately generating electrolyzed acidic ionized water is performed in this equipment. Further, the electrolytic cell used in this embodiment is provided with a diaphragm 36 between the anode 32 and the cathode 34, and the acidic water (electrolytic acidic ionized water) 3 generated on the anode side and the cathode It is configured so that the alkaline water 4 generated on the side of can be taken out separately. Regarding the extraction of the acidic water, it is considered that there is a method of forcibly sucking it by interposing a separate pump and a method of collecting it from the hole at the bottom of the water tank by gravity flow. In this embodiment, the water in the water storage tank is introduced by being divided into the central anode 32 portion and the cathode 34 portions on both sides. Over time, the water level in the electrolytic cell is kept constant.

Further, since sodium chloride (salt) is not added to the raw water (tap water) of the present invention, the raw water (tap water) is allowed to stay in the electrolytic cell for a certain period of time in order to cause the electrolysis reaction efficiently. Need to put. By passing through this step, tap water can sufficiently undergo electrolysis without addition of sodium chloride (salt). In addition, because acidic ionized water cannot always flow to the ice maker because it is retained for a certain period of time, when it is introduced from the water storage tank to the electrolytic cell, it is intermittently controlled by a valve that is temporally controlled. Is supplied in a regular manner. The acidic ionized water transferred from the electrolyzer can be intermittently transferred from the upper part of the electrolyzer to the ice making machine by the power of a pump or the like, but in the embodiment shown in the drawings, electrolysis is performed by opening and closing a valve. A method is adopted in which acidic water is taken out by gravity flow from a hole provided at the bottom of the tank.

The ice making device 40 is a commonly used ordinary ice making machine, and the acidic ionized water 3 produced in the electrolytic cell is used.
Is automatically and sequentially made within a fixed time limit to produce an electrolytic acid ion ice 5, and an ice making process is performed. The structure does not matter as long as it is a machine that freezes a certain amount of water to produce ice. However, since the ice produced by the present invention is used for the purpose of transporting fresh fish meat and maintaining the freshness, which is an industrial purpose, it is necessary to produce a certain amount on an industrial scale. The ice-making capacity of the machine also requires a certain amount or more.

The apparatus used in the method for producing electrolytic acidic ion ice described above is an embodiment of the apparatus for producing electrolytic acidic ion ice according to the present invention, and includes a water tank 10 for retaining tap water described above. , Valves (valves) 21, 21a, 21 equipped with a control device 22 for intermittently introducing tap water into the electrolytic cell
b, 21c, 21d, an electrolytic cell 3 equipped with an anode 32 and a cathode 34 and provided with a diaphragm 36 between the anode and the cathode
0 and an acidic ionized water 3 produced in the electrolytic cell are automatically and sequentially ice-made to produce electrolytic acidic ionized ice 5.
It consists of 0 and.

[0016]

The electrolytic acid ion ice producing method and apparatus according to the present invention have the above-mentioned constitutions.
It has the following effects. Electrolytic acid ion ice, which is frozen acidic ion water with bactericidal action, is mass-produced in an industrially available industrial amount, so freshness can be maintained when transporting fresh fish meat, and even if ice is thawed, sterilization is performed. Since it is a strong acidic ionized water, it is fundamentally different from the conventional method and apparatus for keeping freshness in that it can maintain the freshness and at the same time has a bactericidal action even after dissolution. Also, when used in ordinary stores, etc., the intended purpose can be sufficiently achieved in terms of maintaining freshness and sterilizing action after dissolution. Also, since sodium chloride (salt) is not added to tap water during electrolysis, chlorine gas will be generated after dissolution, odor (chlorine odor) will be generated, discoloration and taste of water will deteriorate. No worries.

At the same time as the production of the electrolytically acidic ionized water, the production is industrially carried out by sequentially shifting to the ice making process, so that the production amount is large, so the supply is sufficient, and in addition, cost reduction due to mass production can be expected. Therefore, it can be provided relatively inexpensively. Further, since the diaphragm is provided between the anode and the cathode of the electrolytic cell, the acidic ionized water can be easily separated and transferred. The electrolysis process that separates and produces electrolyzed acidic ionized water
By introducing tap water intermittently and keeping tap water in the electrolysis tank in a static state, it is possible to continuously produce pure electrolytic acidic ion ice without interposing sodium chloride (salt). Became. A water tank, a valve that intermittently introduces tap water into the electrolyzer, an electrolyzer, and an ice-making device that automatically and sequentially makes acidic ionized water produced in the electrolyzer are combined together. Since it has a structure, all the steps can be performed with this one machine, and it becomes possible to inexpensively mass-produce electrolytic acid ion ice that could not be mass-produced in the past, and it is possible to use it on an industrial scale. It is now ready for use.

Further, the electrolytic acidic ionized water can be obtained by simply supplying the acidic ionized water having sterilizing power and tap water to the electrolytic cell. Also, since sodium chloride (salt) is not added to tap water during electrolysis, chlorine gas will be generated after dissolution, odor (chlorine odor) will be generated, discoloration and taste of water will deteriorate. No worries. Anyone can easily obtain acidic ionized water by intermittently supplying tap water from the water tank to the electrolytic tank with a diaphragm between the anode and the cathode, which is temporally controlled by a valve. It has become possible.
