Description

[Detailed explanation of the invention] <Industrial application field> This invention softens the tissue of tea leaves while
This invention relates to a tea grinder that evaporates water, and particularly to a spatula device for kneading tea leaves.

<Prior Art> Generally, a tea grinder and a spatula used therein have a configuration shown in FIG. 3.

That is, a breathable, air-permeable bottom plate 2 made of bamboo material and woven into a semi-cylindrical shape is provided on the upper part of the machine frame 1, thereby forming a coarse chamber 3 in the upper part of the machine frame 1.

A hot air supply section 4 is provided at the upper rear side of the coarse chamber 3.
In addition, an inlet 5 for supplying tea leaves and an outlet 6 for taking out tea leaves are provided at the top plate and the lower part of the bottom plate 2 on the front side of the roughening chamber 3, respectively.

A prismatic rotating shaft 7 is installed in the coarsening chamber 3 located at the axial center of the bottom plate 2, and a leaf scraper 8 and a spatula 9 are attached to the rotating shaft 7.

The spatula 9 is formed by bending a thick sheet metal material into a wave shape, and its base end 9a, that is, the end in the direction in which the rotating shaft 7 rotates, is connected to the lower end of the L-shaped swinging arm 10. Connector 11 consisting of bolts and nuts is attached to 10a.
Connect removably. and swing arm 1
No. 0 had a structure in which the bent portion 10b was supported by a pin at the tip of a support arm 12 protrudingly fixed to the rotating shaft 7, and the upper end portion 10c was connected to the support arm 12 by a spring 13.

The tea processing machine configured as described above feeds tea leaves from the input port 5 and supplies hot air from the hot air supply section 4 into the coarsening chamber 3, while grinding the leaves through the rotating shaft 7. Then, rotate the spatula 9 to the right as shown by arrow A. As a result, while steaming the tea leaves in the coarsening chamber 3, the tea leaves are repeatedly pressed against the coarsening bottom plate 2 by the spatula 9 and stirred by the leaf coarser 8, thereby coarsening the tea leaves. It's becoming like that.

By the way, during the above-mentioned coarse operation, some of the coarsely crushed tea leaves adhere to the spatula 9, but if the adhered tea leaves are left as they are, the amount of the adhered tea leaves will gradually increase. As it grows, it peels off from the spatula 9 at a certain stage, forms a lump, and mixes with the tea leaves in the rough chamber 3.

This may reduce the coarsening performance of the coarsening machine, or the clumped tea leaves from the previous time may be mixed into the next tea leaves, impairing the quality.

For this reason, conventionally, the spatula 9 has been removed periodically to remove the tea leaves attached to the spatula 9.

However, since the spatula 9 requires strength, it must be made of a thick plate and must be firmly attached to the swing arm 10.

For this reason, the work of removing the spatula 9 has the drawback of requiring labor and time.

<Problems to be Solved by the Present Invention> The purpose of the present invention is to cover the outer surface of the spatula with a cloth bag that can be easily attached and removed, thereby making it easier to remove deposits.

<Means for solving the problems> In order to achieve the above object, the present invention is constructed as follows.

A semi-cylindrical bottom plate has a rotating shaft at its axial center, a swinging arm extending radially outward from the rotating shaft, and a tip of the swinging arm is attached to the bottom plate. A tea processing machine having a spatula facing the inner surface of the spatula, characterized in that the outer surface of the spatula is removably covered with a cloth bag having an opening with a chuck in the longitudinal direction of the center. .

<Function> Since the present invention has the above structure, the deposits generated by the rough action of the spatula adhere to the outer surface of the cloth bag.

Therefore, by removing the cloth bag from the spatula, the deposits can be easily removed.
Furthermore, since this cloth bag has an opening with a chuck in the longitudinal direction of its center, it is extremely easy to attach and detach.

<Example> Hereinafter, an example in which the above configuration is embodied will be described based on the drawings.

FIG. 1 shows an embodiment of the cloth bag of the present invention. spatula 3
An opening 32 with a chuck 31 is provided in the longitudinal direction of the center portion of the cloth bag 30 covering the cloth bag 5. A single-layer (meaning that it is not a bag) connecting part 33 is provided at the upper end of the cloth bag 30, and a metal hook 34 with both ends curled inward is attached via this connecting part 33. This hook 34 allows the mounting bracket 34 provided on the spatula 35 side to
1, and fix the cloth bag 30 to the spatula 35. That is, the opening 32 is opened by the chuck 31.
Open it, put the cloth bag 30 over the spatula 35, hook the hook 34 on the mounting bracket 341, and attach the cloth bag 30. In this way, the cloth bag 30 will not come off the spatula 35 during rough work.

If the spatula 35 is covered with such a cloth bag 30, all the deposits will adhere to the cloth bag 30. To remove the deposit, open the opening 32 with the chuck 31 and remove the cloth bag 30 from the spatula 35.
Then, the cloth bag 30 is soaked in hot water or water to soften the deposits, and then removed with a suitable brush or the like.

The cloth bag 30 from which the deposits have been removed is connected to the spatula 35 in the same manner as described above.

Here, since the cloth bag 30 can be obtained at low cost, it becomes easy to prepare spare parts in advance. In this case, if the cloth bag 30 with the deposits is replaced with a spare cloth bag 30, the downtime of the rough-washing machine can be further shortened.

<Effects of the invention> As explained above, according to the structure of the invention,
By covering the spatula with a cloth bag that can be easily attached and detached from the spatula, it is possible to easily and quickly remove deposits.
