[0021] In the embodiment, the fermentation box 1 is the core container of the whole fermentation process, and the fermentation box 1 provides a closed and controllable environment, which provides a basic condition for the fermentation process of tea.

[0022] The fermentation cylinder 2 is rotatably installed in the fermentation box 1, which not only increases the contact area of tea and air and promotes the uniform fermentation of tea, but also allows the temperature and humidity to exchange between the inside and outside of the cylinder, thereby further improving the fermentation efficiency.

[0023] The sealing door 3 is hingedly installed on the fermentation cylinder 2, which facilitates the loading and unloading of tea and ensures the sealing property during the fermentation process, thereby reducing the influence of external factors on the fermentation process.

[0024] The spray pipe 4 and the atomizing nozzle are fixedly installed on the top inner wall of the fermentation box 1, which maintains the constant humidity in the fermentation box 1 by spraying water mist, thereby avoiding the influence of excessive drying of tea on the fermentation quality. This design also helps to clean the inner wall of the fermentation cylinder 2 and reduces the adhesion of tea.

[0025] The air outlet frame 5 is arranged at the rear side of the fermentation cylinder 2 and can be knocked by the knocking mechanism. During the fermentation process, the knocking mechanism drives the air outlet frame 5 to knock the fermentation cylinder 2 at regular intervals, effectively removes the tea adhered to the inner wall of the cylinder, prevents the hole from being blocked, thereby ensuring the good temperature and humidity exchange between the inside and outside of the fermentation cylinder 2, and significantly improves the fermentation efficiency.
