Tea fixating apparatus and tea processing method

Abstract

The invention relates to the technical field of tea processing, and specifically discloses a tea fixating apparatus and a tea processing method. The tea fixating apparatus comprises the following parts: a fixating tube; a first fixating screen, a second fixating screen and a third fixating screen which are sequentially arranged inside the fixating tube from the top to the bottom; and a vibrating part which is used for allowing the first fixating screen or the second fixating screen to vibrate up and down. A hot air circulation chamber is arranged, in isolated arrangement, at an inner bottom ofthe fixating tube via a clapboard with through holes; and a draft fan is arranged inside the hot air circulation chamber. The tea fixating apparatus disclosed by the invention is capable of carryingout hot-air fixation when tea leaves are vibrated to fall; so that, piling of tea leaves during fixation is avoided. Moreover, uniform hot air circulation and distribution are ensured, so that, high tea fixation efficiency and full fixation effect are achieved so as to have tea quality improved; moreover, the tea fixating apparatus also has a dust-removing effect.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a tea greening device and a tea processing method. Background technique [0002] Existing green tea tealeaves processing generally comprises three steps of finishing, rolling and drying. Tea greening is to destroy and passivate the oxidase activity in fresh tea leaves by high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, evaporate part of the water in fresh leaves, make tea soft, easy to knead and shape, and emit green odor at the same time Taste, a tea-making step that 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, pre...

AI Technical Summary

Problems solved by technology

[0003] However, the existing tea processing methods do not clean or manually clean the tea leaves before they are greened. If the tea leaves are not cleaned, the pesticides and other substances contained in the tea leaves will greatly affect the taste of the tea leaves. Manual cleaning of the tea leaves is time-consuming and laborious, and it is very expensive. It may cause damage to the tea leaves, and there is also the problem of incomplete cleaning

[0004] The existing tea greening equipment has the disadvantages of low work efficiency, long time for greening, and easy stacking of tea leaves during the greening process, resulting in insufficient greening, which affects the quality of tea processing
