Multilayer tea leaf fixation system

Abstract

The invention discloses a multi-layer tea leaf fixation system, and relates to the field of agricultural processing equipment. The multi-layer tea leaf fixation system comprises a feeder, a vibration device, a metal adsorber, a conveying device, a primary microwave fixation device, a secondary microwave fixation device, an infrared dehydration conveying device, a cooling device, a mounting frame and a center console, the conveying device comprises a first-stage conveying unit, a second-stage conveying unit and a third-stage conveying unit; the first-stage microwave fixation device comprises a plurality of groups of first-stage microwave generation boxes, and the second-stage microwave fixation device comprises a plurality of groups of second-stage microwave generation boxes. The technical problems that in the prior art, the green tea fixation time is long, the tea leaves are prone to being stacked together in the fixation process, the tea leaves at dead corners are heated unevenly, consequently, fixation is insufficient, and the tea leaf processing quality is affected are solved.

Description

technical field [0001] The invention relates to the field of agricultural processing equipment, in particular to a multi-layer tea greening system. Background technique [0002] Green tea processing includes three processes of greening, rolling and drying. Greening is to destroy and passivate the oxidase activity in fresh tea leaves through high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, evaporate part of the water in fresh leaves, and make the tea leaves turn green. It is soft, easy to knead and form, and at the same time emits a green odor, which promotes the formation of a good aroma. Tea rolling is a tea-making process that properly destroys the tea tissue, allows the content of the tea to penetrate the surface of the leaf, and at the same time shapes the tea, so that the buds and leaves are tightly rolled into the desired shape. Tea drying is a tea-making process that evaporates excess water in tea leaves, prevents them from going ...
