Hereinafter, with reference to the drawings will be described in detail. However, these drawings are for illustrative purposes only and the present invention is not limited thereto.

1 is a flow chart of the desalination method in one embodiment according to the present invention.

Referring to Figure 1, the desalination method according to the present invention, salting step (100) for pickling with salts or salts such as potassium chloride, general salts, organic acid salts such as acetate in the food to be salted, demineralized water generating step (110) ), The salting step (100) consists of a desalination step 120 to soak salted food in salted water in demineralized water.

Salting step 100 uses a conventional salting method known in the art. For example, you can spray radishes with high concentrations and store them for a long time.

Salting step 100 may be used for food already salted with a high concentration. That is, when using already salted food, salting step 100 may be omitted in the present invention.

In the demineralized water generating step 100, the demineralized water generating device of FIGS. 2 to 4 is used.

The electrode of the demineralized water generating device used to produce demineralized water is about 10cm × 10cm × 1mm, and it uses 15 pole plates, total voltage is 4 ~ 6V, current is about 40 ~ 60A, and the amount of water is used. It is about 40 ~ 60ℓ / min. The number, size, voltage, current and flow rate of the electrode can also be adjusted as needed.

Demineralized water is weakly alkaline demineralized water and weakly acidic demineralized water when + and -electrodes are applied to the pole plates, as the number of pole plates according to the applied electricity is different. If necessary, the size of the electrode plates may be different from each other to produce weakly alkaline demineralized water and weakly acidic demineralized water.

That is, weakly alkaline demineralized water is produced when the number of pole plates to which + electricity is applied is generated, and weakly acidic demineralized water is produced when the number of pole plates to which + electricity is applied is greater. Also, if the number of pole plates is the same and the size of the pole plate to which + electricity is applied is greater than the size of the pole plate to which-electricity is applied, slightly alkaline demineralized water is produced, and on the contrary, the weakly acidic demineralized water is produced. do.

Weak alkaline demineralized water and weakly acidic demineralized water should be applied differently depending on the organization of salted food and acidity of food. In the case of fruit and leafy vegetables such as radishes and cucumbers, it is preferable to use weakly alkaline demineralized water. Bulbs, such as onions, it is preferable to use weakly acidic demineralized water.

Raw water for making demineralized water is used by dissolving salt, potassium chloride and acetate in general groundwater or tap water. The concentration of salt, potassium chloride and acetate is about 2.5 ~ 3%. Concentrations of the salt, potassium chloride, acetate, and the like may be appropriately modified as necessary.

EXAMPLE

The demineralized water generator used 15 10cm × 10cm × 1mm electrodes (8 electrodes + + 7 electrodes-producing weak alkaline demineralized water), 5V voltage and 50A current. The yield was 50 L / min to produce demineralized water.

20 kg of radish salted in 16.204% was added to 100 L of the demineralized water, and the remaining salt concentration was measured by desalting with time.

In addition, 20 kg of radish salted at 16.204% was added to 100 l of general tap water, and the salt concentration of the salted radish remaining after desalting with time was measured.

The measurement results are shown in <Table 1>.

<Table 1> Salinity of Salted Radish by Treatment Time in Demineralized and General Waters

<Table 1> shows that the pre-treatment concentration was 16.204% in demineralized water and normal water, and the salt concentration of salted radish desalted in demineralized water was 3.701% and the salted demineralized salt in normal water after 160 hours after treatment. Salinity concentration was 10.04%. In normal water, the salt concentration dropped to 6.7% after 20 days of treatment.

2 is a structural diagram of a demineralized water generating device according to an embodiment of the present invention.

2, the inflow path 20 is located at the bottom of the main body 30 having a rectangular cross section, and the outflow path 60 is located at the top.

Raw water 10 is supplied to the inflow path 20, and an additive 12 is supplied. As the additive, an electrolyte such as salt or calcium chloride is usually used. In the present invention, since it is intended to chemically change the raw water, it is preferable to add the additive (12).

Water introduced from the inflow path 20 flows evenly distributed between the + pole plate 40 and the-pole plate 50 via the flow path forming means 32 as necessary. The flow path forming means 32 is installed as necessary to minimize the change in flow rate as it is closer or farther from the inflow path 20. When the inflow path 20 is separately provided in the flow path between the pole plates, the flow path forming means 32 may not be necessary.

Water flows between the positive electrode plate 40 and the negative electrode plate 50.

Different electricity is applied to the positive electrode plate 40 and the negative electrode plate 50. For example, when the positive electrode is applied to the positive electrode plate 40, the negative electrode is applied to the negative electrode plate 50. If necessary, + electrode is applied to the positive electrode plate 40 and + electricity is applied to the positive electrode plate 50.

The plus and minus plates are named for convenience of description and are not named for the polarity of electricity applied.

The pH and ORP change depending on what electricity is applied to the positive electrode plate 40 and the negative electrode plate 50. For example, when + is applied to the positive electrode plate 40 and-is applied to the negative electrode plate 50, the number of the positive electrode plates to which the positive electrode is applied is greater, so that alkaline water exceeding pH 7 is generated (ORP is-). In the opposite case, acidic water below pH 7 is produced (ORP is +) because the number of negative plates to which-is applied is greater. In addition, when + electricity is applied to only one of the four positive plates 40 without applying electricity, and-electricity is applied to four of the positive plates 50, neutral water (ORP is +) of pH7. Is generated. Since substantially no tap water is completely neutral (pH7), the neutral water according to the present invention does not mean completely neutral (pH7). Neutral water in the present invention means having an intermediate pH between acidic and alkaline water.

Water generated in the main body 30 is discharged to the outside through the outlet (60).

The water discharged through the outlet 60 may be connected to a suitable machine or apparatus, or may be used for various purposes as necessary.
