Constant-temperature wine brewing fermentation tank

The invention relates to the technical field of wine brewing fermentation, in particular to a constant-temperature wine brewing fermentation tank which comprises a tank body, a supporting plate mechanism is fixedly connected to the center of the outer surface of the front end of the tank body, a first machine shell is fixedly connected to the center of the outer surface of the front end of the tank body, and a first motor is fixedly connected to the upper end of the inner surface of the first machine shell. Two rotating shafts are fixedly connected to one end of an output shaft of the first motor, and the end, close to the first motor, of one rotating shaft penetrates through the tank body and is connected with a driving wheel in a penetrating mode. According to the tank, fermented raw materials can be quickly moved out, manpower and material resources consumed in the raw material transferring process are reduced, saccharomycetes conduct aerobic respiration for reproduction in the initial stage of fermentatio
