Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of black tea processing, and particularly relates to an impurity removal and screening mechanism for black tea processing. Background Art
[0002] Black tea belongs to fully fermented tea, which is made from suitable new tea leaves of tea trees through a series of technological processes such as withering, rolling, fermentation, and drying. Withering is an important process in the primary processing of black tea. When black tea is in the primary processing stage, it is called dark tea. Black tea gets its name because the tea soup and leaf bottom color after brewing the dry tea are red. During the processing of black tea, chemical reactions centered around the enzymatic oxidation of tea polyphenols occur, and the chemical components in the fresh leaves change greatly. The tea polyphenols are reduced by more than 90%, and new components such as theaflavins and thearubigins are produced. The aroma substances are significantly increased compared to the fresh leaves. Therefore, black tea has the characteristics of black tea, red soup, red leaves, and sweet and mellow taste. After being picked, black tea is mixed with many impurities, and the impurities mixed in the tea leaves will reduce the quality of the tea. Therefore, it is necessary to clean the impurities before processing black tea.
[0003] The prior art has the following deficiencies: In the prior art, a screening device for black tea processing with the publication number of CN202220323957.X includes a screening frame. Fixed strips are fixedly arranged at the four corners of the top of the screening frame. Springs are fixedly arranged on one side of each fixed strip. One ends of two springs corresponding to each other in position are respectively fixedly connected to the two ends of one side of the frame, and one ends of the other two springs are respectively fixedly connected to the two ends of the other side of the frame. A screen is fixedly arranged at the bottom of the inner wall of the frame. Two damping rods and two electric telescopic rods are respectively fixedly installed on both sides of the top of the screening frame. Spring rods are fixedly arranged at the top of each electric telescopic rod and the top of each damping rod. The tops of the four spring rods are respectively fixedly connected to the four corners of the bottom of the frame.
[0004] When the above device is in use, although it is convenient to screen black tea, during the working process, it is difficult to achieve a good screening effect through a single screening frame. At the same time, springs are arranged on both sides of the frame to connect the fixed strips, and it is difficult to push the frame and the screen significantly by controlling the electric telescopic rods to work, thus making it inconvenient to pour out the screened black tea, resulting in certain limitations during the working process.
