2. Description of the Related Art Green tea, black tea, oolong tea and the like that we drink are tea leaves obtained by processing and refining raw leaves collected from tea trees through various processes. When making tea, while maintaining the unique hue of the tea leaves and reducing astringency and bitterness, we carefully process and purify so that the unique taste and aroma of tea can be maximized. Is being done.

In the conventional tea making, in order to reduce astringency and bitterness, the tea leaves are heated by a hot plate, hot air, far-infrared radiation, microwave radiation, or the tea leaves are treated at a high pressure of 5000 atm or more. The process is being used.

Water consisting of clusters penetrates into cells of animals and plants and is a source of cell functions. The color, taste, and scent of water itself or animals and plants are determined by the various components dissolved in the cluster.

Further, as a result of the above research, by subdividing the water clusters, the specific gravity increases, and the specific gravity permeates well into the cells of animals and plants to activate them. As a result, various oxides and heavy metals such as It is known that pollutants are separated and removed to purify water.

For these reasons, as a method for purifying water by subdividing water clusters and obtaining healthy and delicious water, electromagnetic waves of various wavelengths, particularly far infrared rays, electrolysis, and magnetism are used. The use of electricity, the use of static electricity, etc. are conceivable, and there are various water purifiers and health appliances devised and invented by applying each of them.

[0008] Among these water purifiers, there is an electronic water manufacturing apparatus that uses static electricity. This is to purify water by placing water in a container on an insulator, generating an electrostatic field by an electron charger attached to this container, and subdividing water clusters by this electrostatic field. Is.

A nuclear magnetic resonance apparatus is used as a measuring instrument for measuring the size of water clusters.

[0010]

However, in the conventional processing of food and drink as described above, particularly in the processing of tea,
Since the tea leaves are heated by a hot plate, hot air, far-infrared radiation, etc., there is a problem that the quality, especially the hue, of the tea leaves deteriorates due to oxidation.

Further, due to the recent influence of air pollution and pesticides, the removal of pollutants contained in all edible plants through rainwater and spray water has become a problem.

Further, there is a problem that a device for preventing deterioration during processing of tea leaves is large and expensive.

Therefore, there is a problem to be solved by a processing method and a processing apparatus for maintaining and improving the quality by subdividing water clusters contained in foods and drinks, especially tea. .

The value of the order is larger than that in the case of one metal plate, and the effect of improving the quality retention of tea leaves is increased. The insulating sheet has a function of not releasing static electricity to the outside.

In the above structure, when a pipe is formed by covering the inner and outer surfaces of the metal cylinder with an insulator, a high electrostatic potential is generated in this pipe. Therefore,
Because tea leaves can be put into a pipe and processed,
There is no need to cover it with an insulating sheet, and the pipe can rotate freely.
