JPH07194359A - Pulverization process for food, pharmaceutical, etc. - Google Patents

Abstract

PURPOSE:To obtain a pulverization method effective for preventing the temperature increase in pulverization and preventing the oxidation of the pulverized product and, accordingly, preventing the change and degradation of tea leaf components and enabling the expectation of extremely good symptoms in human body different from the efficacy of conventional tea by drinking in the case of ground tea and, in the case of coffee, preventing the dissipation of color and fragrance and improving the preservability. CONSTITUTION:This process for the pulverization of foods, pharmaceuticals, etc., comprises the beating of foods or pharmaceuticals with a hammer 2 in vacuum or in nitrogen atmosphere.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder processing method for foods, pharmaceuticals, etc., and particularly to a powder processing method for powdered green tea, coffee, etc.

[0002]

2. Description of the Related Art Conventionally, when powdering green tea etc.,
It was done by grinding raw tea with a stone mill.

[0003]

However, in such a conventional powder processing method, the raw material is easily oxidized during the powder processing, and as a result, in the green tea, the tea leaf component is changed / altered, and the coffee However, it has a disadvantage that the color and flavor are easily dissipated and the storage stability is easily deteriorated.

An object of the present invention is to eliminate such inconvenience.

[0005]

In order to achieve the above-mentioned object, in the powder processing method for foods / medicines, etc. according to the present invention, the foods / medicines are hammered into powder in a vacuum or nitrogen. It is characterized by.

[0006] Alternatively, the food / medicine can be hammered into powder to extract DNA in vacuum or nitrogen.

Further, it is possible to hit the food / medicine with a hammer in a vacuum or in a nitrogen atmosphere to form a powder, and to mix the fine particles due to the natural abrasion of the hammer material due to the hitting with the powder.

[0008]

Since the method for processing powder of foods, pharmaceuticals, etc. according to the present invention is configured as described above, it is possible to prevent the temperature from rising during the processing of powder and to prevent the oxidization of powdered products. Is something that can be done.

Further, if the food / medicine is hammered into powder in a vacuum or in nitrogen to extract the DNA, oxidation can be prevented and the original DNA can be extracted.

Furthermore, if the food / medicine is hammered into powder in a vacuum or nitrogen and fine particles due to natural abrasion of the hammer material due to this tapping are mixed with the powder, what is desired to be mixed is the material of the hammer. By doing so, the powder can be easily mixed.

By performing the pulverization while supplying nitrogen gas, it is possible to prevent the temperature from rising during the powder processing and to prevent the powder from being oxidized by oxygen generated during the pulverization. can do.

[0012]

1 is a casing. The casing 1 is composed of a main body 11 and a lid 12, and a raw material tea M for matcha is stored inside. Reference numeral 2 denotes an iron hammer installed in the casing 1, which is manually or mechanically operated. The raw material tea M is pulverized by the operation of the hammer 2.

Reference numeral 31 denotes a gas supply pipe, which is the casing 1
It is installed on the lid 12 of. Reference numeral 32 denotes a gas exhaust pipe, which is installed in the main body 11 of the casing 1. Nitrogen gas is supplied into the casing 1 through the gas supply pipe 31, and is discharged to the outside through the gas discharge pipe 32. Therefore, the casing 1 is always filled with nitrogen gas. Therefore, when the material tea M is hit with the hammer 2 to be pulverized, it is possible to prevent oxidation and prevent an increase in the temperature of the atmosphere. The powdered powder is taken out of the casing 1 by opening the lid 12. In addition, when it is desired to maintain the inside of the casing 1 in a vacuum state, the gas supply pipe 31 is closed and the gas exhaust pipe is
The air in the casing 1 may be discharged by suctioning through 32. Then, the material tea M can be pulverized in a state where oxidation is prevented.

[0014]

The powder processing method for foods / medicines, etc. according to the present invention can prevent temperature rise during powder processing because the foods / medicines are hammered into powder in a vacuum or in nitrogen. In addition to being able to do so, it is possible to prevent the powdered one from being oxidized.

Therefore, if this powder processing method is used,
The raw material is less likely to be oxidized during powder processing, so that in matcha etc., it is possible to prevent changes and alterations of tea leaf components, and it is possible to expect very good various symptoms different from conventional efficacy in the human body after drinking. In coffee, it is possible to prevent the loss of color and flavor and improve the storage stability.

Further, if the food / medicine is hammered into powder in a vacuum or nitrogen to extract the DNA, oxidation can be prevented and the original DNA can be extracted.

Furthermore, if the food / medicine is hammered into powder in a vacuum or nitrogen and fine particles due to natural abrasion of the hammer material due to this tapping are mixed with the powder, the desired material is mixed with the hammer material. By doing so, the powder can be easily mixed.

If the powdering is carried out while supplying nitrogen gas, the temperature rise during powder processing can be prevented and the powder can be prevented from being oxidized by oxygen generated during powdering. can do.
