Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a rolling device for accelerating the enzymatic oxidation of polyphenol compounds in black tea. Background Art

[0002] Black tea is the young leaves or buds of the tea plant of the Theaceae family. Black tea does not grow naturally, but was made on the basis of green tea in the late Ming and early Qing dynasties. It is made from suitable new leaves of tea trees and is refined through a series of processes such as withering, rolling (cutting), fermentation, and drying. The fermentation causes a chemical reaction in the ingredients in the tea leaves, and when brewed with water, it not only has a pleasant aroma, but also has a unique dark red tea color, so it is called "black tea".

[0003] The processing of black tea includes the step of rolling, which usually destroys the cell tissue of the tea leaves, causing the tea juice to overflow, and the leaves are rolled into tight straight strips, reducing their size, so that the tea juice overflows on the surface of the leaf strips, forming a shiny and oily appearance. Therefore, the rolling device for enzymatic oxidation of polyphenols in black tea is an indispensable auxiliary device in the processing of black tea.

[0004] The existing patent (publication number: CN215602978U) discloses a black tea kneading device with a simple structure, convenient kneading of tea leaves, reduced damage and improved efficiency. A kneading pot is arranged on the frame; a first rotating shaft is arranged in the middle of the kneading pot, and a kneading block is arranged on the first rotating shaft near the bottom of the kneading pot, and there are three kneading blocks, which are evenly distributed along the circumference of the first rotating shaft; a transmission mechanism matched with the first rotating shaft is arranged on the frame. The black tea kneading device of the utility model, through the cooperation of the frame, support legs, kneading pot, first rotating shaft, kneading block and transmission mechanism, when kneading, put the black tea into the kneading pot, and drive the first rotating shaft to rotate through the transmission mechanism, and then drive the kneading block to rotate. Compared with the violent kneading in the prior art, it can greatly reduce the damage to the fresh black tea leaves, and greatly improve the efficiency compared with manual kneading. It has the characteristics of simple structure, convenient kneading of tea leaves and reduced damage. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. When the existing black tea rolling device is in use, part of the black tea is often squeezed at the edge of the device and cannot be fully rolled. At this time, the black tea at the edge needs to be cleaned manually, which is time-consuming and labor-intensive, thereby greatly reducing the practicality of the equipment; 2. In the production process of some black tea, the black tea is mostly rolled manually, and manual rolling greatly reduces work efficiency. In addition, long-term rolling can easily cause wrist pain to the staff, thereby greatly increasing the labor intensity of the workers. Utility Model Content
