JPH07203852A - Method for removing green tea incrustation of green tea manufacturing machine - Google Patents

Abstract

PURPOSE:To reduce labor for operations to remove green tea incrustations and improve the operating efficiency of a green tea manufacturing machine by sprinkling (warm) water on a specific site at a prescribed time before completing a green tea manufacturing step and removing the green tea incrustations in the green tea manufacturing machine. CONSTITUTION:This method for removing green tea incrustations is to sprinkle water or warm water into a rolling drum when the green tea manufacturing machine is a rough rolling machine and on a rolling board when the machine is a rolling and twisting machine at a prescribed time during a processing step for the green tea leaves or before completing the step, further continuously operate the green tea manufacturing machine during the remaining time of the step and thereby infiltrate the water or warm water into green tea incrustations sticking to members such as rolling hands 3, leaf scrapers 4 and bamboo duckboards 11 or the rolling board, soften the incrustations, then rub the softened incrustations with the green tea leaves during the processing and remove the tea incrustations. Specifically, e.g. a solenoid valve is opened on a signal from a control panel 5min before completing the step of the rough rolling machine to sprinkle water passing through a water sprinkling pipe 2 from nozzles 10 in the rolling drum.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing tea astringency in a tea making machine.

[0002]

2. Description of the Related Art In the prior art, in the case of a rough kneader, a sponge, scrubbing brush, etc. and water or warm water are periodically put in a kneading cylinder, the main shaft is rotated, and the sponge, scrubbing brush, etc. are stirred and adhered. The tea astringent is removed. Also, the tea astringent that has adhered to the kneading machine's kneading machine is scraped off with a spatula or the like.

[0003]

[Problems to be Solved by the Invention]
The machine's astringent work is carried out on a regular basis because it adversely affects the quality of the product, but it is labor intensive, and since the machine cannot be used during the astringent work, the manufacturing efficiency will decrease. There has been a long-felt need for an invention of a method for removing tea astringent, which has problems, requires less labor, and does not lower the production efficiency.

[0004]

[Means for Solving the Problems] The means according to the present invention comprises: a process for processing tea leaves of a tea making machine;
Sprinkle a predetermined amount of water or warm water in the kneading cylinder in the case of a rough kneader, or on the kneading machine in the case of a kneading machine, and continue to operate for the rest of the process, water or warm water The method is to remove the tea astringent by infiltrating and softening the tea astringent with the tea leaves being processed.

[0005]

[Function] When water or warm water is sprayed for a predetermined time before the end of the process during the tea leaf processing step of the tea making machine, the tea astringent adhering to the member in contact with the tea leaf is infiltrated with the water or hot water, and the tea astringent Becomes soft. The tea astringent adhering to the member is rubbed against the tea leaves, so that the tea astringent adhering to the member is removed.

[0006]

Embodiments will be described with reference to the drawings. 1 is a front view of the rough kneader, and FIG. 2 is a schematic cross-sectional view of a side surface of the rough kneader.
In the case of the present embodiment, the solenoid valve 12 is opened for 15 seconds 5 minutes before the end of the rough kneading process. The opening / closing signal of the solenoid valve is sent from the control panel 1. The solenoid valve is opened for 15 seconds, and about 2 liters of water is sprayed from the nozzle 10 into the kneading barrel through the spray pipe 2. Since the process is near the end, 3 kneading hands, 4 leaf zaray, 11 bamboo duck
The tea astringent is adhered to, but the sprinkled water infiltrates the tea astringent, becomes soft, and is abraded by the agitated tea leaves to remove the tea astringent. In the case of the present embodiment, the main components to which the tea astringent adheres are the kneading hands 3, the leaf lining 4, and the bamboo duck 11 parts. The material of the rubbing hands 3 and the leaf shavings 4 is iron, and the material of the bamboo duck 11 is bamboo, but in order to enhance the effect of removing the tea astringent, a polymer material having good peeling property on the surfaces of the rubbed hands 3 and the leaf shavings 4. Alternatively, the bamboo duck 11 may be coated with a polymer material. FIG. 3 is a schematic front sectional view of the kneading machine, and FIG. 4 is a plan view. Even in the case of a kneading machine, 15 minutes on the kneading machine 15 from the small hole in the direction of the kneading machine 15 opened in the sprinkler pipe 5 minutes before the end of the process.
Sprinkle about 2 〓 of water per second. The sprinkling signal is output from the control panel (not shown) like the rough kneader, and the sprinkling solenoid valve (not shown)
To drive. Since the process is near the end, tea astringent is stuck on the kneading board 15. When the tea astringent is infiltrated with water and becomes soft, it is rubbed by the agitated tea leaves and the tea astringent on the kneading machine is removed. still,
Since the amount of water varies depending on the water pressure and the diameter of the sprinkling pipe, the sprinkling time was determined while confirming the actual effect of removing tea astringent.

[0007]

EFFECTS OF THE INVENTION The present invention uses the above-mentioned method, which reduces the labor of the operator, the equipment cost is low, and the tea astringent can be removed in each step, so that the quality of the product can be improved and the tea making can be cleaned to remove the tea astringent. Since there is no need to stop the machine, it has the effect of improving the operating efficiency of the machine.
