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.
