Multistage coarse and fine screening device for black tea processing

Abstract

The invention provides a multistage coarse and fine screening device for black tea processing. The multistage coarse and fine screening device for black tea processing comprises a power switch and a storage drawer. The interior of a main body is of a hollow structure. The top of the main body is provided with a feed port. The feed port is located on the top of a material crushing screen. Three motors are mounted on the rear end face of the main body through bolts. The three motors are in transmission connection with three outer wheels through belts. The outer wheels are mounted at the outer ends of coupling shafts. The coupling shafts are rotatably connected to the left and right ends of the main body. Inner wheels are mounted at the inner ends of the corresponding coupling shafts. The multistage coarse and fine screening device for black tea processing is provided with three connecting rods. One end of each connecting rod is rotatably connected to the corresponding inner wheel. The multistage coarse and fine screening device for black tea processing can drive screens in the device to swing up and down and back and forth. When the screens swing up and down, the multistage coarse and fine screening device for black tea processing implements screening on tea leaves in the screens and can conduct irradiation and sterilization on the tea leaves by using an ultraviolet sterilizationlamp in cooperation when screening the tea leaves in the device to kill harmful bacteria in the tea leaves and improve the cleaning quality of the tea leaves.

Description

technical field [0001] The invention belongs to the technical field of black tea processing, and more specifically relates to a multi-stage rough and fine screening device for black tea processing. Background technique [0002] Black tea originated in China. The earliest black tea is called Lapsang Souchong. It was created by the ancestors of the Jiang family in Tongmu Village, Xingcun Town, Wuyishan City, Fujian Province in the middle and late Ming Dynasty. The Jiang family in Tongmu Village, Wuyishan City is a tea family that produces Lapsang Souchong black tea. It has a history of more than 400 years. After the black tea is processed, people often use professional screening devices to screen the black tea due to the different sizes and specifications of the black tea. . [0003] The inventor found through searching that there is an existing similar device, such as a black tea screening device with reciprocating disturbance mentioned in patent application number 201721641...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a multi-stage coarse and fine screening device for black tea processing, to solve the problem that the existing similar devices have poor screening effect on black teas of various specifications, small-sized black teas and medium-sized black teas It cannot be separated and screened out effectively, which will easily affect the screening effect of black tea; and the sterilizing effect on the screened black tea is poor, and the black tea is likely to contain some bacteria inside, which will affect the quality of the black tea itself
