The invention relates to the technical field of black tea processing equipment, and particularly discloses a black tea fermentation device. The black tea fermentation device comprises a black tea fermentation device body and an air supplying unit, wherein the black tea fermentation device body comprises a mounting barrel and a rotating shaft; a fermentation barrel is fixed in the mounting barrel;a waste air opening is formed in the top of the mounting barrel; a plurality of air outlet holes are formed in the fermentation barrel; the rotating shaft is vertically arranged and is driven by a motor; the rotating shaft is rotatably connected with the mounting barrel and the fermentation barrel; fermentation baskets are fixed to the rotating shaft in the fermentation barrel; hollow stirring rods are respectively and rotatably connected to the inner wall of the fermentation barrel located above each fermentation basket; a plurality of exhaust holes are formed in each stirring rod; flexible blades are arranged on each stirring rod; a driven bevel gear is fixed to each stirring rod; a driving bevel gear which is meshed with each driven bevel gears is arranged on the rotating shaft; and theair supplying unit is used for providing oxygen containing moisture to the stirring rods. Through the adoption of the black tea fermentation device disclosed by the invention, the problem that in theprior art, in the fermentation course of tea leaves, the tea leaves are not uniform in fermentation and even rotten because of local superheating is solved.
Description
technical field [0001] The invention relates to the technical field of black tea processing equipment, in particular to a black tea fermentation device. Background technique [0002] Fermentation in tea generally refers to a simple oxidation. When tea leaves are placed in an enzymatic or hot and humid environment, a series of reactions such as oxidation and hydrolysis will occur in the tea leaves, the most important of which is the oxidation promoted by polyphenol oxidase and peroxidase, which makes the tea polyphenols in the tea leaves Matter changes. [0003] Existing tea fermentation is usually carried out in a fermentation tower. Before fermentation, the operator sends the tea to be fermented into the fermentation tower, and feeds oxygen containing moisture into the fermentation tower to ensure the oxygen needed during the tea fermentation process. and moisture. Since the fermentation of tea leaves usually takes 4-8 hours, the fermentation time is relatively long, and...
