At the same time, the anti-skid plate 12 set at the bottom end of the support column 11 can increase the friction between the device and the ground, thereby avoiding the device from slipping during use. The feces to be fermented are poured into the fermentation tank 2 of the device. After the feces are filled, the staff closes the feed port and starts the servo motor 21 on the bottom plate 1 of the device.
