JPH0947220A - Spray device in raw leaf cutter for tea manufacturing - Google Patents

Abstract

PROBLEM TO BE SOLVED: To uniformly cut raw tea leaves uneven in length by such a way that a raw leaf cutter for tea manufacturing is mounted with a spray nozzle and circular rotary edges are sprayed with high-pressure water, tap water or hot water to remove tea incrustations before solidification thereof to keep the rotary edges clean and to smooth cutting of the raw tea leaves. SOLUTION: A tap water pipe is set up for feeding water onto the side of the upper part of a raw leaf cutter for tea manufacturing and the tip of the piping 1 is mounted with a spray nozzle 2 so as to face on circular rotary edges 3. The cutter is made up of the many circular rotary edges 3, a shaft 4, a belt 5 for driving the rotary edges, and a motor 6 for driving the rotary edges. On charging raw tea leaves from above, they are cut while passing between two sets of the rotary edges 3 mounted on the shaft 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tea leaf cutting machine for making tea, which is capable of uniformly cutting the size of irregular tea leaves before the step of producing tea.

[0002]

2. Description of the Related Art Fresh tea leaves are No. 1 tea (April-May), No. 2 tea (June-July), No. 3 tea (August-September), No. 4 tea, Autumn-winter tea (September-October) ), And there are several times a year when fresh tea leaves are harvested. Depending on the time of plucking, the length of the plucked green tea leaves is different, and the length is uneven, and the long ones become several tens of centimeters. Since it is difficult to make tea from the buds of long fresh tea leaves as is, using a fresh tea cutting machine for tea making equipped with multiple circular rotary blades,
It is made into tea after being cut into a few centimeters long.

However, when a fresh tea cutting machine for tea making is used for a long time, the astringency of tea adheres to the circular rotary blade and the sharpness deteriorates. Therefore, conventionally, the tea astringent that adheres to the circular rotary blade after being used for a long time is manually removed by using a chisel-shaped tool by stopping the tea leaf cutting machine.

[0004]

In the prior art, during cutting of fresh tea leaves, the tea astringent adheres to the tip and both side surfaces of the circular rotary blade, and the cutting edge is covered with the tea astringent, making it impossible to cut the fresh tea leaves. Since the fresh tea leaves are continuously fed, when they are no longer cut, the fresh tea leaves are clogged in the fresh tea cutting machine for tea making and the circular rotary blade stops. When the circular rotary blade stops, the motor driving the circular rotary blade stops, or
Burn out. Further, there is a problem that the rotary blade driving V-belt is damaged.

Further, in order to remove the tea astringency of the circular rotary blade, the raw tea cutting machine for tea making is stopped, the production efficiency is lowered, and the work of removing the tea astringent is also a manual work, which is dangerous.

According to the present invention, the circular rotary blade is covered with tea leaves,
The purpose of the invention is to prevent the circular rotary blade from sticking to the circular rotary blade so as to prevent the rotary blade driving motor, the rotary blade driving V-belt and the like from being broken due to the sharpness of the rotary blade being stopped.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention relates to a tea leaf cutting machine having a large number of circular rotary blades, wherein the circular rotary blade of the tea leaf cutting machine has high pressure water,
A spray nozzle is provided so as to spray either tap water or warm water, and a means for spraying is used as appropriate.

[0008]

As described above, the high pressure water, tap water, or hot water is sprayed onto the circular rotary blade with the spray nozzle while the fresh tea leaves are being cut, whereby the tea astringency of the circular rotary blade is removed.

[0009]

EXAMPLES Examples will be described with reference to the drawings.
FIG. 1 is a schematic diagram of a tea leaf cutting machine provided with a spraying device, and FIG. 2 is a sectional view.

A water supply pipe 1 is connected to the upper side surface of a fresh tea cutting machine for tea making with a water pipe, and a spray nozzle 2 is attached to the tip of the water supply pipe 1 toward a circular rotary blade 3. The tea leaf cutting machine is composed of a large number of circular rotary blades 3, a circular rotary blade shaft 4, a rotary blade driving V-belt 5, a rotary blade driving motor 6, and the like. When you put fresh tea leaves from the top,
The green tea leaves are cut while passing between two sets of circular rotary blades 3 attached to the shaft 4.

In this embodiment, tap water is sprayed onto the circular rotary blade 3. When spraying automatically, the solenoid valve 7 is opened / closed by the solenoid valve opening / closing timer 8 to start and stop spraying. The setting of the electromagnetic valve opening / closing timer 8 may be appropriately adjusted by observing the state of fresh tea leaves. When tap water is sprayed during cutting of fresh tea leaves, the astringent tea adhered to the circular rotary blade 3 is removed.

Normally, tap water can be used to remove tea astringency, but when there is a lot of tea astringency, high-pressure water, warm water, etc. are effective. After the completion of cutting the fresh tea leaves, it is recommended to operate the fresh tea cutting machine for tea making for about 10 minutes. In this case, the solenoid valve 7 is kept open and tap water is sprayed.

[0013]

Since the present invention is constructed as described above, it has the following effects. Before the astringent tea sticking to the circular rotary blade is hardened, it is frequently removed, the circular rotary blade is kept clean and the cutting is performed smoothly. Therefore, the conventional accidents such as the burnout of the rotary blade drive motor and the damage of the rotary blade drive V-belt are eliminated.
It has the effect of fully utilizing the function of the raw leaf cutting machine for tea making.

Furthermore, since it is no longer necessary to manually clean, safety and efficiency can be improved.
