Tea leaf processing multistage sieving device

Abstract

The invention relates to a tea leaf processing multistage sieving device which comprises a sieving support plate. A collection box is installed in the middle of the upper end face of the sieving support plate and further plays the effect of collecting sieved tea leaves. Four sieving support pillars are symmetrically installed on the upper end face of the sieving support plate. Sieving mechanisms are installed at the upper ends of the four sieving support pillars and conduct primary sieving on the tea leaves. The inner wall of each sieving support pillar is provided with a damping branched chain. A sieving box is installed on the upper end faces of the four damping branched chains of the four sieving support pillars. First kidney-shaped sieving holes are evenly formed in the bottom end faceof the sieving box. The front end face and the rear end face of the sieving box are symmetrically provided with two vibration motors through motor bases. The two vibration motors are used for drivingthe sieving box to conduct secondary sieving on the tea leaves. The tea leaves of the medium size are left in the sieving box, and the small tea leaves enter the collection box to be collected through the first kidney-shaped sieving holes. By adoption of the tea leaf processing multistage sieving device, the automatic multistage sieving function of the tea leaves can be achieved, no manual operation is required, operation is easy and convenient and the degree of automation is high.

Description

[0001] This application is a divisional application of a Chinese patent application with the application number 2016107719062 filed on August 30, 2016, and the title of the invention is a multi-stage screening device for tea. technical field [0002] The invention relates to the technical field of tea processing, in particular to a multi-stage screening device for tea processing. Background technique [0003] China is a big country for tea tasting, and there are many famous tea brands, such as West Lake Longjing, Tieguanyin, Biluochun, Huangshan Maofeng, black tea, green tea, etc. With the demand of consumers, the amount of tea planted in various places is increasing. The tea processing process is mainly divided into five steps: picking, spreading, screening, rough frying and fine frying. Picking is mainly to pick the tea leaves from the tea tree; spreading is also called greening, and the main process is to turn the picked tea leaves After the pine is spread out on the gree...
