A tea screening mechanism

Abstract

The invention discloses a tea screening mechanism, which comprises a screening machine and a wind separator connected with the screening machine. The screening machine is provided with at least two layers of screens, and the screens divide the screening machine into at least three screening chambers. , each screening room is correspondingly connected with several winnowing machines with different wind power through the transmission device. The present invention uses the combination of multi-stage sub-sieves and multi-level corresponding wind speeds to sort tea leaves, and the wind selection accuracy has been greatly improved; the equipment has strong continuity and high degree of automation, which reduces the labor intensity of workers; Add other impurity removal devices, such as electrostatic impurity removal devices, etc., to screen other impurities that cannot be removed in tea leaves by winnowing, and further improve the impurity removal rate.

Description

technical field [0001] The invention relates to tea processing equipment, in particular to a tea screening mechanism. Background technique [0002] Tea processing is a complicated job. Each individual tea leaf usually has to go through more than a dozen or even twenty procedures to ensure the quality of the final product. At present, the initial screening of tea leaves in the tea processing industry generally adopts a flat circle. sieve, but in the prior art, only one standard is often used to screen tea raw materials, which results in uneven thickness of tea raw materials and more impurities after screening. , a single wind speed should correspond to the processing of tea raw materials with uneven thickness, which greatly reduces the impurity removal rate of the equipment, and also increases the difficulty of processing in the later process. Contents of the invention [0003] The problem to be solved by the present invention is to provide a tea sieving mechanism for the ...
