Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the modification of drinking water (soft drink, mineral water, juice, coffee, milk, black tea, green tea, a mixture thereof, etc.) and liquor to which electrolysis or electrodialysis is applied. The present invention relates to an apparatus and a method for performing the same.

[0002]

2. Description of the Related Art Conventionally, many methods have been used for modifying drinking water (soft drink water, mineral water, juice, coffee, milk, black tea, green tea, and mixtures thereof) and alcoholic beverages. . Some typical methods are described.

[0003] pH adjustment using additives such as chemicals,
A method of performing a treatment such as oxidation prevention. A method of modifying proteins by causing protein denaturation by heat. There is a method of storing the solution in a tank for a long period of time and aging it.

However, no matter which method is used,
There is some problem. For example, when a chemical is used, a problem of safety of the beverage itself occurs. When heat is used, the oxidation reaction occurs more vigorously than at room temperature, so that there is a possibility that the quality may deteriorate. Further, when the aging treatment is performed, a time is required for the aging treatment itself, and there is a possibility that a problem such as oxidation occurs at the same time as the aging and the quality of the product is deteriorated.

[0005] As a remedy, there are conceivable methods such as not adding a chemical to a product, performing treatment without heating, or adding an apparatus that does not cause an oxidation reaction in an aging process.
Each is very difficult to achieve.

[0006]

SUMMARY OF THE INVENTION Drinking water (soft drink,
When considering the improvement of the quality of mineral water, juice, coffee, milk, black tea, green tea, mixtures thereof and liquors, the first problem is oxidation. Oxidation reduces the quality of the product. In the present invention, it is a first object of the present invention to improve the quality by causing an electrochemical reaction of an oxidation or reduction reaction in a solution without using a chemical. The second problem is a problem of improving the hydration of components other than water contained in the beverage. When ingredients other than water are not well-dissolved in water, the taste itself may be curled, and in many cases it cannot be said that the beverage is of good quality. Since the above-mentioned electrochemical reaction works effectively to improve (age) the hydration, improvement (aging) of the hydration is a second problem.

[0007]

As means for solving the problems, a voltage is applied to drinking water (soft drink water, mineral water, juice, coffee, milk, black tea, green tea, a mixture thereof, etc.) and liquor, and at that time physical Apply the electrochemical oxidation and reduction reactions that occur. In the present invention, a process with a relatively large processing current and a small processing voltage is called electrolysis, and a process with a relatively small processing current and a large processing voltage is called electrodialysis.

A method of applying a voltage to a solution is a method of immersing an electrode in the solution and applying a voltage to the electrode. This device (a component of the device for applying a voltage to the solution) is called an electrolytic cell or an electrodialysis cell in the present invention. The type of the electrolytic cell or the electrodialysis cell is systematically as shown in FIG. 1, and the electrolytic cell or the electrodialysis cell is used properly according to the difference of the target solution and the processing purpose.

Hitherto, such electrolytic treatment or electrodialysis treatment has been used only for a limited solution such as treatment with water alone or generation of hypochlorous acid by electrolysis of saline. This method is used for drinking water (soft drinks, mineral water, juice,
Coffee, milk, black tea, green tea, mixtures of these, etc.)
In addition, the present invention is directed to pouring alcoholic beverages and alcohol directly into an electrolytic cell or an electrodialysis cell and subjecting them to electrolytic treatment for the purpose of reforming them. In this treatment method, as compared with the modification treatment method using an additive such as a chemical, only electricity is supplied to the solution, so that treatment without adding any chemical can be performed. Regarding the improvement of hydration (aging), in the treatment such as aging of alcoholic beverages, the instantaneous electrolytic treatment increases the hydration of alcohol and can cause the same change as alcohol stored for a long time.

As a feature of this treatment method, reduction reaction and oxidation reaction are caused only by electric power without using chemicals, so that controllability is good, and reduction and oxidation reactions are selected by applying diaphragm technology. Can be done Regarding the improvement of the hydration property, the aging treatment can be performed more efficiently than the conventional method by subjecting the product to direct electrolytic treatment or direct electrodialysis treatment.
