The utility model provides a domestic fungus fermenting installation, belongs to biological fermentation technical field, characterized by: the wind gap intercommunication is gone into to control boxair outlet and fermentation cylinder, another air exit intercommunication of control box return air inlet and fermentation cylinder, the steam port of control box through with fermentation cylinder steam connector intercommunication, set up the vent on the control box top, set up one way check valve in the below of first fan, set up the various control device of control installation in the controlbox to correspond with the regional button of the control operation that sets up surface outside the control box and be connected, set up manometer and control valve at the fermentation cylinder, fermentation cylinder jar body central authorities link to each other with balanced support frame through the connecting axle of balanced support frame, set up a jar body hatch door in one side of the fermentation cylinder jar body, the opposite side of personally experiencing sth. Part of the body at the fermentation cylinder jar sets up the motor, and at the internal stirring subassembly that setsup of fermentation cylinder jar, the stirring subassembly links to each other with the motor, set up netted bottom plate in the fermentation cylinder and below the stirring subassembly. The beneficialeffects are that: so that the zymophyte of fermenting installation bottom can not yin gaowen and be killed, and then promotes single production fermentation process's output, reduction in productioncost has improved fermentation efficiency and quality, has increased fermented output.
