Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing sterilized treated water for fresh food, which is sold at a fresh food store such as a supermarket, a convenience store, or a department store, and a disinfectant generated by the apparatus. The present invention relates to a method for processing cut vegetables using treated water.

[0002]

2. Description of the Related Art Conventionally, when processing vegetables such as cut vegetables such as cut vegetables and lettuce whose leaves are cut from fresh food products, Escherichia coli and other substances are particularly processed. Since general viable bacteria are easily mixed, it is common practice to use a 200 ppm solution of sodium hypochlorite and immerse the cut vegetables in the solution for sterilization.

[0003]

In the conventional sterilization treatment using a 200 ppm solution of sodium hypochlorite, even if the vegetables are subsequently washed with water, a hypochlorite smell remains and the taste and feeling are respected. There was a problem that it did not meet the needs of consumers.

[0004] The cut vegetables thus treated are
There is also a problem that the crunchiness of fresh vegetables is lost, and the texture of the vegetables becomes less fresh.

[0005] Furthermore, the cut vegetables treated as described above cannot sufficiently sterilize Escherichia coli and other general viable bacteria,
There is also a problem that Escherichia coli and other general viable bacteria grow significantly over time.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for producing sanitized water, which is capable of sterilizing fresh food products such as cut vegetables without using chemicals, and an apparatus for producing sanitized water produced by the apparatus. The purpose is to provide a processing method for the cut vegetables used.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides an apparatus for generating metal ionized water, and an apparatus for converting metal ionized water generated by the apparatus for generating metal ionized water to an alkali having an arbitrary potential. It is characterized by including an electrolysis generator for electrolyzing into water and acid water, and a water storage tank for separately storing alkaline water and acid water generated by the electrolysis generator.

In this case, the present invention provides a device for generating metal ion water used in the above-mentioned processing, comprising a water tank, a pump device, and a metal ion adding means provided between the pump device and the water tank. This metal ion adding means is constituted by one or more ceramic filters and one or more metal ion generating filters, and water in the water storage tank is passed through the metal ion adding means using the pump device. It can be configured to return to the water storage tank and circulate again.

The present invention also provides alkaline water produced by electrolyzing metal ion water when processing cut vegetables, which has a negative potential that is difficult for microorganisms to inhabit. It is characterized by using alkaline water.

[0010] Further, the present invention is an alkaline water produced by electrolyzing metal ion water when processing cut vegetables, which are one of the fresh food products, and it is difficult for microorganisms to inhabit the alkaline water. Alkaline water having a negative potential of-and acidic water produced by electrolyzing metal ionized water, which has a potential of-which is difficult for microorganisms to inhabit. It is used.

[0011]

According to the first aspect, the metal ionized water ionized by the metal ionized water generator has an electric potential of-of an arbitrary value that cannot be inhabited by microorganisms such as bacteria through the electrolytic generator. It is electrolyzed into alkaline water and acid water with a positive potential, and stored in separate storage tanks.

According to the second aspect, the water in the water storage tank passes through the ceramic filter via the pump device, and is pulverized from water of a large molecular population to water of a small molecular population by the far-infrared irradiation effect. Then, it reaches the metal ion generating filter, where it becomes water bearing metal ions and is returned to the water storage tank again. After repeating this circulation for a required time, it is converted into metal ion water and sent to the electrolysis generator.

When the living environment of bacteria is measured by the reduction potential,
It is known that bacteria, whether aerobic, anaerobic, or facultatively anaerobic, cannot live in alkaline water having a potential of -400 mV or less. Therefore, when the vegetables before the cutting process or the vegetables after the cutting process are immersed in alkaline water having a potential of -400 mV or less as in claim 3, the bacteria can respond to the living environment. Without death.

[0014] When the cut vegetables thus treated with alkaline water are immersed in acidic water having a positive potential as described in claim 4 above, the above-mentioned bacterium becomes +960 mV.
In the oxidized state having the above potential, it cannot similarly inhabit, so bacteria that have been eradicated by immersion in alkaline water or washing treatment, or survived by sterilization,
The bacteria are removed or sterilized by treatment with an acidic water having a positive potential of +960 mV or more, which again causes a drastic change in the living environment.

[0015]

The portion that comes into contact with water is made of, for example, a corrosion-resistant material such as a synthetic resin.

Reference numeral 9 denotes a means for generating metal ion water, not shown, but a plurality of ceramic filters 10 filled with ceramics for generating far-infrared rays therein, and also not shown, but internally. Nickel, manganese, cobalt, copper, zinc, magnesium, etc. human body needs 1
K, Na, Ca, Mg, Z, which are seven kinds of minerals
n, Cr, Fe ² , Cd, Co, Ni, Pb, H, C
A plurality of ring-shaped metal plates made of a metal component of u, Ag, Hg, Pt, and Au are suspended at intervals so that they do not come into contact with each other, and water flows through the inside. One or two metal ion generating filters 11
Consisting of In addition, the structure and the combination method are not limited as long as the above-mentioned metal plates are configured so that water can flow and do not contact each other.

The metal ion water generating means 9 receives the water in the water storage tank 4 through the pump device 8 and circulates the ceramic filter 10 and the metal ion generating filter 11. Here, water is applied to the ceramic filter 10.
By passing through the inside, water of a large molecular population is changed to water of a small molecular population. Further, by passing through the metal ion generating filter 11, the metal of various metal plates such as nickel, manganese, cobalt, and copper described above is formed. The ionized water is returned to the water storage tank 4 through the communication pipe 12 and circulated for a required time such as 30 minutes.

Incidentally, the metal ion water generating apparatus 3 having the above configuration is an example, and is not limited to the embodiment.

Returning again to FIG. 1, in FIG. 1, as described above, water is generated in the metal ion water generating device 3 and becomes small water of a molecular group. Ion water is sent from the water outlet 13 to the electrolysis generator 14. Here, it is decomposed into a required amount of alkaline water and acidic water having a required electric potential by electrolysis, and the alkaline water is separately stored in the alkaline water tank 15 and the acidic water is separately stored in the acidic water tank 16.
From there, it is sent to the processing plant for fresh food via the pumps 17,18.

The actual method of use is as follows. First, water such as tap water is poured into the water storage tank 4 from the faucet 2 through the water softener and / or the filter 1 to fill the capacity, and then the pump device 8 is operated. Then, the water in the water storage tank 4 is sent to the metal ion water generating means 9 through the water supply pipe 4a and the water supply pipe 8a, and further returned to the water storage tank 4 again through the communication pipe 12, and
Circulate for about a minute. Then, the water in the water storage tank 4 becomes small water of a molecular group through the ceramic filter 10 and becomes metal ion water having metal ions of various metal plates through the metal ion generation filter 11. The ionic water is sent to the electrolytic generator 14, where it is decomposed into alkaline water having a potential of -400 mV or more and acidic water having a potential of +960 mV or less, for example.
Water is stored in an alkaline water tank 15 and an acidic water tank 16, respectively. At this time, the tap water is designed so that it only comes into contact with a metal plate such as platinum, which is an electrode plate, in the electrolysis generator, and does not come into contact with any other metal.

The environment in which the microorganisms inhabit is irrespective of whether it is an aerobic bacterium, an anaerobic bacterium or a facultative anaerobic bacterium.

As shown in Table 1, it is limited to a strong acidity of 2.7 or more in terms of pH, a strong alkalinity of 11.3 or less, an oxidation state of +960 mV or less in oxidation-reduction potential, and a reduction state of -400 mV or more. Living in a range.

-40 generated by the apparatus for generating sterilized treated water
Alkaline water having a negative potential of 0 mV or more and acidic water having a positive potential of +960 mV or less obtained by electrolyzing this reduced water have greatly removed the living sphere of microorganisms. I can't live.

[0026]

[Table 1] By the way, such alkaline water and acidic water can be obtained by electrolyzing ordinary tap water with an electrolysis generator. However, the present invention requires the production of metal ion water before sending the ordinary tap water to the electrolysis generator. The feature is that the metal ionized water is passed through the device. With this configuration, the state in which the molecular population is small is maintained even when the water is electrolyzed through the electrolysis generator and becomes alkaline water and acidic water. Alkaline water and acidic water generated by electrolyzing metal ionized water adhere to vegetables or come into contact with water contained therein, and their potential does not change in a short time. The effect can be enhanced. As a result, for example, with regard to the disinfecting effect, the following cases are used depending on whether the device for generating metal ion water is used or not.

Table 2 shows such a difference. In the description of the present invention in this specification, the germicidal effect or the germicidal effect refers to the germicidal effect by the washing effect of alkaline water and acidic water having a small molecular population, and the bactericidal activity of alkaline water and acidic water. And both of the disinfection effects of In each of the following tables, R
ED means alkaline water and OX means acidic water.

[0027]

[Table 2] When no metal ion generator is used (conventional example)

[0028]

[Table 3] In the case of using a metal ion generator In the case of using metal ion water generated through a metal ion water generator, the elimination rate of general viable bacteria can be significantly increased. I understand.

Next, using the alkaline water and the acidic water produced using the metal ionized water as described above, the immersion test of the typical cut vegetable cabbage was performed by changing the number of hours.
When the number of general viable bacteria, the texture, and the state of syneresis were examined, the results shown in the following tables were obtained.

[0030]

[Table 4] In the case of cabbage (when using a device for generating metal ionized water) above

As can be understood from Table 4, the alkaline water and the acidic water produced by using the metal ion water produced by the apparatus for producing metal ion water through the electrolytic producing device adhere to vegetables such as cabbage. It can be seen that the potential of the alkaline water and the acidic water does not change even after 20 minutes when contacted with the contained moisture. Since the bactericidal effect is maintained in this way, the bactericidal effect is enhanced.

Next, an experiment was conducted on the effect of removing sub-smell using shredded cabbage.

The results shown in Table 5 were obtained. In the following table, S
(Control) indicates a conventional example. put it here,
Alkaline water (RED) obtained by electrolyzing metal ion water generated through a metal ion water generation device using an electrolytic generation device and 200 p of sodium hypochlorite
A mixture of the pm solution was used to conduct a reaction test as to whether or not a new product was produced. However, only a slight change in pH was observed, and no product produced by both reactions was found.

[0032]

[Table 5] Next, we investigated the effect on texture using cut lettuce.

The results as shown in Table 6 were obtained. The following table

In Table 6, S (control) indicates the case where ordinary tap water was used.

[0033]

[Table 6] Next, when a cut treatment was performed using cabbage to examine the water separation effect, compared to the case of the conventional example (S control),

Table 7 shows the differences.

[0034]

[Table 7] As can be seen from the above survey results, Table 2. According to the experimental example, even when immersion treatment with only alkaline water was performed, an extremely high sterilization effect was exhibited. When immersion treatment using acidic water was added thereto, as shown in other experimental examples in Table 4, Furthermore, the disinfection effect is increased, and the alkaline water and the acidic water obtained by electrolyzing the metal ion water through the metal ion water generating device with the electrolytic generating device are short even when they come into contact with the water content of the vegetables. Since the potential did not change with time, it was found that the propagation of various bacteria could be suppressed even after a long time after draining.

Further, as shown in Table 5, when used in combination with a conventional treatment method using a sodium hypochlorite solution without using acidic water, there is an effect that the hypoodor can be eliminated. I understand.

Further, when immersion treatment using both alkaline water and acidic water is carried out, as shown in Table 6, a crisp feeling similar to fresh vegetables which cannot be expected from those treated by a conventionally known method is obtained. It turns out that it lasts for a long time.

As shown in Table 7, it was found that water separation after processing can be prevented over a long period of time, as shown in Table 7 as compared with the conventionally known processing method.

In the above embodiments, cut vegetables, which are one of the fresh foods, were examined for their effects. However, the sterilized water produced by the production apparatus according to the present invention was Needless to say, it can be used as a disinfecting water even when processing fresh foods other than cut vegetables.

[0039]

Since the present invention is configured as follows, the following operational effects can be obtained.

According to the first aspect, the water molecules are small and the washing effect on bacteria is high, and the cut vegetables can be given a crisp feeling even after processing, and have a high sterilizing effect without using chemicals. It can produce processed water for fresh food products.

According to the second aspect, it is possible to easily produce metal ion water having small water molecules and carrying metal ions of various metal plates.

According to the third aspect, when alkaline water is used in the processing of cut vegetables, the germicidal effect is increased without using a sodium hypochlorite solution, and the metal ions are mixed with various minerals. As a result, it can be taken into the human body, which can provide an effect that it can be used to promote health.

According to the fourth aspect, by using the alkaline water and the acidic water of the first aspect together, the bactericidal effect can be further increased, and the crispness when fresh vegetables are cut is consumed. It can be maintained for a long time until it is transported to the ground and reaches the hands of the consumer, and can also be effective in preventing water separation.
