Description of the Related Art A tea making and kneading machine is configured to put tea leaves into a cylindrical kneading drum having a circular bottom on a kneading machine and circularly move the tea leaves in the kneading drum with a pressing lid. Thus, the kneading action is performed by applying the kneading pressure. In order to apply pressure to the pressure lid, a method of placing a weight on the pressure lid and pressing the weight with the weight of the weight, and a method of pressing the pressure lid against tea leaves with a screw screw are used. The former is performed with a kneading machine for green tea, and the latter is performed with a kneading machine for black tea. In either method, the measurement of the pressing force applied to the tea leaves during the kneading operation and the control of the pressing force and the rotation speed of the kneading drum based on the measured value are not performed.

が発生する。In the kneading step, while applying pressure to the tea leaves, the dried tea leaves and the wet tea leaves are mixed to make the degree of drying between the tea leaves uniform. In addition, the water inside the tea leaves is extruded to the surface by the pressing force, and the surface and the inside water of each tea leaf are made uniform and the fibers are further softened. In the production of green tea, it is possible to eliminate uneven drying of the tea leaves dried by the rough kneading operation in the previous step and to facilitate the next middle kneading operation. In the black tea process, the tea leaves that have undergone the withering process are softened, so that the withering of the withering is uniform and the fermentation is performed on average. If the power applied to the tea leaves is too strong, the tea leaves may be torn or torn and crushed. Also, if the pressing force is not uniformly applied to the entire tea leaf and the tea leaf is not mixed, a phenomenon occurs in which only a part receives an excessive force and a certain part does not receive the force.

している。[0004] Evenly applying a proper pressure to the tea leaves in the tea kneading machine affects the quality of the tea product. The pressure on the tea leaves must be changed according to the volume of the tea leaves in the tea kneading machine, the kneading process time, the degree of leaching of the internal moisture to the surface, the properties of the tea leaves, and the like. For these reasons, it is important to continuously and accurately measure the pressure applied to the tea leaves. It is therefore an object of the present invention to provide a method for adjusting the pressure applied to the tea leaves to an appropriate value and performing efficient kneading, and a device capable of continuously and clearly knowing the pressure applied to the tea leaves.

Also, when the measured value is smaller than the preset pressure, tea leaves may be torn,
In order to increase the kneading action without increasing the risk of tearing, increase the rotation speed of the kneading drum 2 (fast), and when the measured value is greater than the preset pressing force, do not break the shape of the tea leaves. Then, the number of revolutions of the kneading drum 2 is reduced (increased).

The pressure lid 4 is connected to a motor 11 and supported by a screw 12. The pressure lid 4 moves up and down by rotating the sprocket 19 by operating the motor 11. 18 is a detent,
A screw is cut on the inner surface of the sprocket 19, and by turning the sprocket 19 meshing with the screw screw 12, the screw screw 12
The screw screw 12 is provided so as not to turn when it moves up and down along the screw on the inner surface 9. When the measured value is smaller than the preset pressure, the pressurizing lid 4 is lowered to increase the pressure, and when the measured value is greater than the preset pressure, to decrease the pressure, The pressure lid 4 is raised. In this type, unlike the type of FIG.
If it is lowered too much, excessive force will be generated, and the machine may be damaged. When the pressure exceeds a certain level in the load cell 6,
The lowering of the pressure lid 4 is stopped.
