Fuente: WIPO "dairy products" The utility model relates to the technical field of fermentation tanks, and discloses an anti-seepage dairy product fermentation tank, which comprises a supporting plate, a first sealing ring and a fixing frame body, and is characterized in that a tank body is arranged on the supporting plate, the supporting plate is connected with the tank body in a penetrating manner, a bottom column is arranged below the supporting plate, and a second sealing ring is arranged below the bottom column. One end of the bottom column is connected with the bottom of the supporting plate through a fastener, a first sealing ring is arranged in the first notch, and the first sealing ring is fixedly connected with the inner wall of the first notch. According to the anti-seepage dairy product fermentation tank, by arranging the mounting shell and the oil absorption piece, oil can be effectively prevented from permeating into the tank body, during use, a second sealing ring is arranged at the joint of a stirring column and the mounting shell, the oil absorption piece in the mounting shell treats flowing lubricating oil, generated water is separated out, and finally the water is drained through a water drainage pipe; therefore, the fermentation efficiency of the dairy products is improved, and the quality of the dairy products is improved.
