At the same time, the activated carbon in the filter box 16 can deodorize the gas to avoid polluting the surrounding environment with the discharged gas;

[0036] When the fermentation is completed, the staff can open the valve in the discharge pipe 3 to recover the fermented material in the housing 1. During this period, the motor 4 can be started to drive the plurality of stirring rods 6 and the plurality of scraping bars 7 to stir the material to assist in improving the recovery efficiency of the material, and the plurality of scraping bars 7 can scrape off the material adhering to the inner wall of the housing 1.
