[0057] After a period of fermentation, the driving motor is started to drive the driving rack 207 to rotate, and in turn drive a plurality of sub-pushing rings 201 connected thereto to rotate synchronously, drive the sub-pushing plate 202 and the sub-pushing rod 203 to rotate, push and scatter the tea, avoid the tea from blocking and affecting the fermentation, and at the same time form horizontal and vertical cavities in the tea, so that the external air can uniformly and fully pass through the tea, and ensure the uniform dispersion of the tea; at the same time, the tea is vibrated and dispersed every certain period of time, and the specific operation is as follows: the horizontal moving guide rail 401 drives the horizontal moving seat plate 402 to move, and in turn drives the pushing assembly to move until the contact ball 504 moves to the bottom of the supporting screen 208, the vibration motor 505 drives the pushing rod 503 and the contact ball 504 to rotate, and impacts and vibrates the tea on the supporting screen 208, so as to scatter and spread the tea, so as to avoid the tea from blocking and ensure the continuous and stable operation of the fermentation operation.

[0058] According to the humidity sensor 204 in each placement groove 2, the humidity inside the tea is detected, when humidification is needed, the humidification assembly 4 is moved above each placement groove 2 by the horizontal moving guide rail 401, and then the humidifier is started to send out water mist through the spray port 405 to humidify the tea, so as to adjust the humidity of the tea in the placement groove 2.
