Description

[Detailed explanation of the invention] [Industrial application field] The present invention softens the tissue of tea leaves while
The present invention relates to a tea milling machine that evaporates water, and particularly relates to an improvement in the structure of the milling bottom plate that forms the bottom of the coarsening chamber.

[Conventional technology]

Generally, a tea processing machine has the configuration shown in FIG. 2. That is, a kneading bottom plate 2 made of bamboo material and formed into a solder tube shape is provided in the machine frame 1, thereby forming a rough kneading chamber 3 in the machine frame 1. A hot air supply section 4 is provided at the upper rear side of the rough rolling chamber 3, and an inlet 5 for supplying tea leaves and an outlet 5 for taking out tea leaves are provided on the top plate on the front side of the rough rolling chamber 3 and the lower front side of the rolling bottom plate 2. An outlet 6 is provided. A prismatic rotary shaft 7 is installed in the rough kneading chamber 3 located at the axial center of the kneading bottom plate 2, and a leaf scraper 8 and a spatula 9 are attached to the rotary shaft 7.

As shown in FIG. 1, the rolling sole plate 2 is formed by arranging a large number of bottom bamboos 2b made of bamboo material cut into long thin strips on a bottom plate 2a made of a thin metal plate bent into a semi-cylindrical shape, as shown in FIG. The portion that will become the outlet 5 opens downward by a hinge 2c. The spatula 9 is made of a thick sheet metal material curved into a wave shape, and its base end 9a is removably connected to the lower end 10a of the L-shaped swinging arm 10 with a bolt/nut 11. and swing arm 10
The bent portion 10b is supported by a pin at the tip of a support arm 12 which is protruded and fixed to the rotating shaft 7, and the upper end portion 10c is connected to the support arm 12 by a spring 13.

The tea processing machine configured as described above has an input port 5.
Tea leaves are supplied from the hot air supply section 4, and hot air is supplied into the rough kneading chamber 3 from the hot air supply section 4. Then, rotate the rotating shaft 7,
While steaming the tea leaves in the roughening chamber 3 by rotating the leaf colander 8 and the spatula 9 in the direction of arrow A, the spatula 9 repeatedly presses the tea leaves against the kneading bottom plate 2 and the leaf colander 8 stirs the tea leaves. , roughly grind the tea leaves.

By the way, during rough rolling, some of the roughly rolled tea leaves adhere to the spatula 9 as well as the rolling bottom plate 2, but if this adhered tea leaves are left as is,
The amount of adhesion gradually increases, and when it reaches a certain value, it peels off, forms a lump, and mixes with the tea leaves in the rough kneading chamber 3.
It impairs the quality of new tea leaves.

For this reason, in the past, the operation of the machine was periodically stopped to remove the tea leaves that had adhered to the kneading bottom plate 2. However, since the adhering tea leaves are hardened, this removal work is very troublesome and requires a lot of labor and time.

[Problems that this invention attempts to solve]

In order to eliminate the above-mentioned drawbacks, the present invention provides a method for removing deposits attached to the kneading bottom plate by removably attaching a cover that covers the kneading bottom plate to at least a part of the inner surface of the kneading bottom plate. The purpose is to make it easier.

[Means for solving problems]

In order to achieve the above object, the present invention is configured as follows. That is, the kneading bottom plate formed in a semi-cylindrical shape has a rotating shaft at the center thereof, the rotating shaft has an arm extending radially outward, and the tip of the arm faces the inner surface of the kneading bottom plate. This is a rolling bottom plate structure of a rough rolling chamber in a tea making machine having a spatula, in which a cover for covering the rolling bottom plate is detachably attached to at least a part of the inner surface of the rolling bottom plate.

〔Example〕

Embodiments in which the present invention is embodied will be described below with reference to the drawings. Figure 1 shows the rough kneading chamber 3 according to the present invention.
FIG. Reference numeral 14 denotes a part of the rolling bottom plate 2. In this embodiment, it is a cover that covers the inner surface of the rolling bottom plate 2 above the tea leaf outlet 6.
5, and mounting fittings 17, 17 are attached to the upper and lower edges with rivets 16. Mounting bracket 17
is a hook 1 whose upper and lower ends are curled inward, and a cloth 15 is wrapped around the inner curled part, and the outer part is a hook 1 attached to the upper and lower edges of the covered part of the kneading bottom plate 2.
8 and 18 to removably attach the cover 14 to the kneading bottom plate 2. In this embodiment, the cover 14
The portion covered by the tea leaves is set above the tea leaf outlet 6 because tea leaves are most likely to adhere to this portion. The covered portion is not limited to this portion, and may cover the entire surface of the kneading sole plate 2 as the case may be.

According to the above embodiment, since the part of the kneading bottom plate 2 above the outlet 6 where tea leaves are most likely to adhere is covered with the cover 14, all tea leaves adhere to the cover 14 in this part. For this purpose, the cover 14 is removed from the rubbing bottom plate 2, soaked in boiling water or water to soften the deposits, and then removed by scrubbing with a suitable brush or the like. Washed cover 14
will use again.

Here, since the cover 14 can be obtained at a low cost, by preparing a spare part and replacing it with this, it becomes possible to further shorten the down time of the roughing machine.

[Effect of idea]

As explained above, according to the configuration of the present invention,
A cover with a simple structure is attached to a part of the inner surface of the kneading bottom plate and is easily removable and replaceable, making it possible to remove deposits easily and quickly by removing this cover. .
