Fermentation tank

The fermentation tank comprises a fermentation tank body, a motor is fixedly installed at the top of the fermentation tank body, a stirring rod is fixedly connected to the output end of the motor, stirring blades are fixedly connected to the surface of the stirring rod, and an air pressure monitor is fixedly connected to the right side of the top of an inner cavity of the fermentation tank body. A vacuum pump is fixedly mounted on the left side of the fermentation tank body, a first pipeline is fixedly connected to the input end of the vacuum pump, a second pipeline is fixedly connected to the output end of the vacuum pump, and supporting columns are fixedly connected to the two sides of the bottom of the fermentation tank body. Through the arrangement of the air pressure monitor, the PLC, the third pipeline and the first electromagnetic valve, the problems that an existing fermentation tank does not have the air pressure monitoring function, when the air pressure is too large, explosion is prone to occurring
