Black tea fermentation tower

Abstract

The invention relates to a black tea fermentation tower, which is characterized in that: the top end of a tower core inside a shell is flexibly connected to a tea inlet of the shell, the bottom part of the tower core is suspended on a soleplate inside the shell, and a shaking device is arranged on the inner lower part of the tower core; the tower core presents in a square shape and comprises an air inlet cavity and four fermentation cavities which are formed by extending outwards from the outer side vertical panels of the air inlet cavity, the top part of the air inlet cavity is sealed, and the air inlet cavity and the vertical panels of the fermentation cavities are formed by mesh plates; a plurality of openings on the wall body of the shell are connected into a cooling drying device through an air return pipe, the cooling drying device is connected to the bottom part of the air inlet cavity through an air outlet pipe, and the bottom part of the air inlet cavity is connected with an oxygenation fan through an oxygenation wind pipe. After the black tea in the fermentation process is cooled and dried by dry cool air, high-humidity high-temperature gases are recycled after being processed by the cooling drying device and oxygen which is consumed during the fermentation process is compensated by the oxygenation fan. After the fermentation is completed, the shaking device is started to quickly shake and loosen the black tea which is expanded in the fermentation cavities after being fermented, a door on the bottom part of the fermentation cavity is opened, and the black tea falls into a collecting cabin to enter a next black tea processing procedure.

Description

technical field [0001] The invention belongs to the technical field of black tea fermentation equipment, in particular to a black tea fermentation tower. Background technique [0002] Black tea needs to be fermented during the production process, and the fermentation of black tea is carried out in a fermentation tower. During the fermentation process of black tea, a large amount of high-humidity and high-temperature gas will be produced. It is necessary to cool and dry these high-humidity and high-temperature gases in time, otherwise the quality of black tea will be reduced, and even black tea will rot. Furthermore, the black tea will expand during the fermentation process. After fermentation, the black tea will swell in the fermentation chamber, and people will take out the fermented black tea with great effort. The structure design of the fermentation tower in the prior art is often unreasonable, and there are deficiencies in cooling and drying the high-humidity and high-...

AI Technical Summary

Problems solved by technology

During the fermentation process of black tea, a large amount of high-humidity and high-temperature gas will be produced. It is necessary to cool and dry these high-humidity and high-temperature gases in time, otherwise the quality of black tea will be reduced, and even black tea will rot.

Furthermore, the black tea will swell during the fermentation process. After fermentation, the black tea will swell in the fermentation room, and people will have to work hard to take out the fermented black tea.

The structure design of the fermentation tower in the prior art is often unreasonable, and there are still deficiencies in the high-humidity and high-temperature gas during the cooling and drying of black tea fermentation and the extraction of fermented black tea, which needs to be improved
