Description

Tea leaf rolling machine Technical Field The utility model belongs to the technical field of tea processing, and particularly relates to a tea rolling machine. Background Tea rolling is an extremely important step in the tea making process, and can play roles in shaping tea, destroying cell structures, promoting release of contained substances and regulating flavor of tea. The traditional tea rolling process is completed by manual rolling, but along with the economic development of China, the rolling process is gradually mechanized and automated to improve the tea making efficiency and reduce the labor cost, so that a tea rolling machine is derived. The tea rolling machine is a key device for tea processing, and consists of a rolling barrel, a rolling disc, a gland, a speed reducing mechanism and a motor, wherein the rolling barrel is used for horizontally rotating on the rolling disc when the tea is rolled, and the tea in the rolling barrel is rolled and rolled under the combined action of the pressure of the gland, the reaction force of the rolling disc, the resistance of a rib and the lateral pressure of the rolling barrel, so that the tea is rolled into strips, meanwhile, leaf tissues are moderately damaged, leaf cells are damaged, part of leaf juice is extruded, and the rolling purpose is achieved. However, the existing tea twisting machine has the greatest defects that the twisting barrel and the gland are usually made of metal, so that when twisting is carried out, tea leaves in the twisting barrel are in rigid contact with the inner wall of the twisting barrel and the gland, when the tea leaves in the twisting barrel are moved and rolled, friction force between the twisting barrel or the gland and the tea leaves at different positions of the inner wall of the twisting barrel and the gland is continuously changed, and the stress of the tea leaves is in a state of different sizes, therefore, if the tea leaves are subjected to larger friction force at a certain position of the inner wall of the twisting barrel or the gland, the broken tea leaves are easily damaged, the generation rate of broken tea leaves is increased, and the twisting aim is mainly to destroy the cell structure of the tea leaves instead of the fiber structure of the tea leaves, so that the existing tea twisting machine cannot fully realize the effect. Compared with mechanical rolling, the manual rolling completely avoids the problem that the stress of the tea leaves is larger, because when the tea leaves are rolled by hands, the tea leaves are in flexible contact with the tea leaves due to the fact that the hands have certain flexibility, and the hands can apply certain stress buffering to the tea leaves, and when the hands feel that the reaction force of the tea leaves to the hands is larger, the rolling force can be properly reduced, so that broken tea leaves are avoided due to the fact that the stress of the tea leaves is larger. In view of the above, there is a need for an improved tea rolling machine in the prior art, which is capable of simulating a human hand to flexibly roll tea. Disclosure of Invention The invention aims to provide a tea rolling machine, which aims to solve the problem that the existing tea rolling machine is high in broken tea rate.

As a further preferable aspect of the present invention, the ribs are arc-shaped and uniformly distributed radially around the axis of the kneading disc. As a further preferable aspect of the present invention, the arc-shaped concave direction of the rib is opposite to the rotation direction of the kneading barrel.
