Tealeaf fermentation device

Abstract

The invention discloses a tealeaf fermentation device, and belongs to the technical field of tealeaf processing. The tealeaf fermentation device specifically comprises a fermentation cavity, a rotating shaft, a support frame, a conveying motor and a conveying device. The fermentation cavity is fixed to the support frame, and the cross section of the fermentation cavity is of a big-end-up trapezoidal structure. A semicircular bottom tank is connected to the bottom of the fermentation cavity. The rotating shaft is arranged in the semicircular bottom tank. A spiral blade is arranged on the rotating shaft. One end of the rotating shaft is fixed to the fermentation cavity through a bearing, and extends out of the fermentation cavity. The rotating shaft is in transmission connection with the conveying motor through a belt. A discharge outlet is arranged on the fermentation cavity. A feed tank is arranged at the feed end of the conveying device. The conveying end of the conveying device is located at the top of the fermentation cavity. The tealeaf fermentation device has the advantages that the fermentation effect is good, external debris and bacteria can be prevented from entering the fermentation cavity in a fermentation process, and feeding and discharging after fermentation are facilitated.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a tea fermentation device. Background technique [0002] Dark tea (dark tea) is named because the finished tea is black in appearance. Dark tea belongs to one of the six major tea categories and is a post-fermented tea. The main production areas are Guangxi, Sichuan, Yunnan, Hubei, Hunan, Shaanxi, Anhui and other places. The raw material of black hair tea used in traditional dark tea is relatively mature, and it is the main raw material for pressing pressed tea. The basic technological process of dark tea is greening, initial kneading, fermenting, re-kneading, and baking. [0003] At present, the natural fermenting method is mainly used in the processing of black tea in China. After the tea leaves are greened and rolled, they are fermented by heaping. Heaping fermentation is the key to the quality of dark tea; because the quality of dark tea is formed by the enzymatic action of m...

Problems solved by technology

The traditional stacking fermentation method is: pile the tea leaves together, spread the covered cloth, and carry out fermentation. The traditional stacking stacking fermentation is greatly affected by factors such as temperature, weather, rainfall, etc., and it is easy to be infected with bacteria or other diseases. Impurities will affect its fermentation effect, and the quality of dark tea obtained is not easy to control

Therefore, fermentation tanks or fermentation towers are more and more used, but the feeding process of fermentation tanks and fermentation towers requires manual feeding and discharge process. Because the fermented tea has certain moisture and stickiness, it is not easy to take out the tea leaves.
