[0023] First, the raw materials, microorganisms and water are injected into the tank body 1 through the feed pipe 3. A screen is arranged inside one end of the feed pipe 3 to prevent the fermented material from flowing back into the feed pipe 3. Then, the output shaft of the starter motor 2 is rotated to drive the rotating rod 11 to rotate and drive the cross plate 9 to rotate. Then, the smoothness of the rotation of the rotating rod 11 can be increased through the guide component. Then, the rotating rod 11 rotates to drive the two fixed plates 13 to rotate and drive the two stirring rods 12 to perform orbital stirring. Then, while the stirring rod 12 rotates, the stirring rod 12 can be stirred and stirred by the stirring component while performing orbital stirring and self-rotation stirring. This can increase the mixing effect of the raw materials inside the device, thereby avoiding the problem that the raw materials cannot be fully mixed, resulting in poor fermentation effect. Then, while stirring, the cleaning component is driven to scrape the inner wall of the tank body 1 to avoid the adhesion of organic and inorganic dirt to the tank wall, which is very troublesome to clean, increases the workload and working time, and thus increases the production efficiency of the device. Finally, the fermentation is completed and discharged through the discharge pipe 10.
