Since the bottom of the U-shaped fermentation tank is provided with an aeration pipe, the aeration pipe is connected to the heating blower, so that the material can fully obtain oxygen. The heating blower has its own heating function, and blows hot air into the U-shaped fermentation tank to dry the material and fully contact the air. The turning mechanism turns the material from the bottom to the top during the movement to discharge moisture. The turning mechanism walks along the upper end of the U-shaped fermentation tank. There are several turning arms on the turning mechanism. The turning mechanism can move forward and backward, turn the material regularly, and turn the material evenly. In the case of sufficient oxygen, combined with the uniform turning of the material, the fermentation effect is sufficient, the composting time cycle is reduced, and it can achieve complete decomposition in 15 days, which improves the economic benefits. Since the U-shaped fermentation tank is provided with a transparent roof for closing the top of the U-shaped fermentation tank, sunlight can be directly injected into the U-shaped fermentation tank, the fermentation temperature can be increased, and the fermentation gas can be sealed so as not to leak out.
