Black tea fermentation production method and device

Abstract

The invention discloses a black tea fermentation method and device which are sufficient in oxygen supply and capable of achieving independent fermentation. The black tea fermentation device comprisesa layered structure frame body; tea base fermentation tanks are formed in all layers, and a gap is formed between the upper tea base fermentation tank and the lower tea base fermentation tank; a heating mechanism is arranged on the frame body; the heating mechanism comprises a controller, and the controller is connected with a control power supply, a power supply, a temperature sensor and a buzzerseparately; and a heater connected with the controller is arranged at the bottoms of the tea base fermentation tanks. The original closed fermentation environment is broken through, the multiple independent tea base fermentation tanks are formed in the frame body of the layered structure, and the waiting time is saved; a gap is kept between upper and lower tea base fermentation tanks, so that airpermeability is high, oxygen supply is sufficient, and sufficient fermentation is facilitated; the heater is arranged at the bottoms of the tea base fermentation tanks and used for controlling the fermentation temperature and accurately controlling the fermentation temperature to achieve a variable-temperature fermentation effect; timing working hours is realized, and reminding is performed by the buzzer, so that the tea bases are stirred to be fully and uniformly fermented; wet cloth is adopted for moisturizing, so that observation and moisturizing are facilitated; and work is stopped and reminded regularly, and excessive fermentation is avoided.

Description

technical field

[0001] The invention relates to the technical field of tea production and processing, in particular to a tea fermentation method and equipment, in particular to a black tea fermentation method and device. Background technique

[0002] Black tea is one of the six major tea varieties in my country and is a fully fermented tea. It is a tea refined from a series of processes such as withering, rolling (cutting), fermentation, and drying, using suitable new tea tree leaves as raw materials. Withering is an important process in the initial production of black tea, which is called "black tea" when it is initially produced. Black tea is named for its red tea soup and leaves after brewing dry tea. During the processing of black tea, a chemical reaction centered on the enzymatic oxidation of tea polyphenols occurs, the composition of fresh leaves changes greatly, tea polyphenols are reduced by more than 90%, and new components and aroma substances such as theaflavins...
