Aerobic automatic black tea fermentation chamber capable of realizing gradient temperature control

Abstract

The invention provides an aerobic automatic black tea fermentation chamber capable of realizing gradient temperature control. The aerobic automatic black tea fermentation chamber comprises a fermentation bin, a base, supporting frames and threaded rods, wherein two groups of transverse rail grooves are symmetrically formed in the lower end surface of the fermentation bin, and through holes are respectively arranged on the left side plate and the right side plate of the fermentation bin; two groups of fixing blocks are symmetrically arranged on the left side and the right side of each supporting frame, and fixing rods are externally covered with the fixing blocks; and the upper end of each threaded rod is rotatably connected with the top plate of the fermentation bin, and the lower end of each threaded rod penetrates through the top plate of a fixed box and is rotatably connected with the bottom plate of the fermentation bin. According to the aerobic black tea fermentation device disclosed by the invention, due to an arrangement that the fixing blocks at two ends of the supporting frames are in sleeving to the outer parts of the fixing rods and fixing bolts penetrate through threaded holes to fasten the supporting frames, when different varieties of black tea are fermented, the distance between the two supporting frames can be adjusted, and then, the fixing bolts penetrate through the threaded holes to fasten the supporting frames so as to fix the supporting frames. Operation is easy, and the space utilization rate can be improved.

Description

technical field [0001] The invention belongs to the technical field of tea processing equipment, and more specifically relates to an aerobic automatic black tea fermentation chamber that realizes gradient temperature control. Background technique [0002] Black tea is a kind of tea that people often drink daily. During the processing of black tea, a chemical reaction centered on the enzymatic oxidation of tea polyphenols occurs, and the composition of fresh leaves changes greatly. Tea polyphenols are reduced by more than 90%, and theaflavins are produced. , thearubigin and other new components and aroma substances, with the characteristics of black tea, red soup, red leaves, sweet and mellow, black tea is a fully fermented tea, which is made of suitable new tea leaves as raw materials, after withering, rolling, fermentation, drying A series of processes such as refined tea. [0003] Reference can be made to the patent application number CN201410701660.2, which discloses a b...
