The wine fermentation production device with the stable internal environment comprises an extrusion box and a fermentation outer box, a second motor is fixedly connected to the inner wall of the center of the bottom of the fermentation outer box, the driving end of the second motor penetrates through a fermentation tank and is fixedly connected with a stirring shaft, and an auger blade and a plurality of stirring blades are fixedly connected to the outer diameter of the stirring shaft. A temperature sensor is fixedly connected to the inner wall of the top end of the left side of the fermentation tank, a pressure sensor is fixedly connected to the position, symmetrical to the temperature sensor, of the inner wall of the right side of the fermentation tank, and a circulating pipe is arranged on the outer side of the fermentation tank. Through the structures of the first motor, the second motor, the circulating pipe and the like, the function of extruding the raw materials can be achieved, it can be guaranteed that the raw materials are mixed more sufficiently and evenly, fermentation is in an optimal temperature environment, and the fermentation effect is improved.
