Rolling device for tea leaf processing and rolling method of rolling device

Abstract

The invention discloses a rolling device for tea leaf processing and a rolling method of the rolling device. The rolling device comprises a feeding mechanism, a first rolling mechanism, a second rolling mechanism, a screening mechanism, a conveying mechanism and a controller, wherein the feeding mechanism consists of a machine box, a feeding hopper and an electric control valve; and the rolling device further comprises a drying mechanism, wherein the drying mechanism comprises an exhaust fan, an air pipe, a heating box, a material receiving box, a temperature sensor and an exhaust fan, the exhaust fan is connected to one side of the machine box through screws, the air pipe is connected to a hose clamp on one side of the exhaust fan, one end of the air pipe penetrates through the machine box, the heating box is connected through screws, and five heating elements are arranged in the heating box. The temperature sensor is arranged to be used for detecting the temperature so as to controlthe number of opened heating elements in the heating box, and saving electric energy can be facilitated; a sliding block and a brush are arranged, so that material turning can be facilitated, and thesituation that tea leaves are heated unevenly to influence the color is avoided; and multiple rolling discs are arranged, so that rolling can be facilitated and the rolling effect can be fully improved.

Description

technical field [0001] The invention relates to the technical field of tea rolling, in particular to a rolling device and rolling method for tea processing. Background technique [0002] Kneading is an important process of tea making. Its function is mainly to destroy the tea cells, knead the tea leaves, make the brewed tea strong and mellow, and shape the tea leaves initially. Through rolling, the tea sticks are rolled up, initially forming cords, reducing the volume, and laying the foundation for the beautiful appearance of the finished tea; at the same time, properly destroying the leaf cell tissue of the green tea leaves, part of the tea juice flows out and attaches to the surface of the tea sticks, making the finished tea brew It is easy to bubble out when soaking. The principle of tea rolling is to let the green (or withered) leaf mass move in a parallel circular motion at a uniform speed in the kneading barrel, and be subjected to the compound action of the multi-dir...

AI Technical Summary

Problems solved by technology

[0003] The existing application publication number is a high-efficiency tea rolling device in CN107980948A patent, which realizes multiple rolling and has a drying process in the middle. The transportation device has a heating and drying effect on the tea leaves, but the tea leaves will not be turned when passing through the transportation device. Tea leaves in the flattening device are easy to accumulate on the transport device. Long-term heating will cause uneven heating of the tea leaves and affect the color. After the rolling is completed, there will be debris, but the device is not equipped with a screening device.
