Probiotic fermented beverage sterilization tank apparatus
ActiveCN224441750Uaid in entryPromote production
This utility model discloses a sterilization tank device for probiotic fermented beverages, including a container mechanism and a cleaning mechanism. The container mechanism includes a tank body, a lid that snaps onto the top of the tank body, and a high-temperature pipe penetrating the top of the lid. The cleaning mechanism involves cleaning the inside of the tank by re-closing the lid, introducing clean water and detergent through the high-temperature pipe, activating a hydraulic cylinder, and driving a transmission rod to reciprocate, causing an extension plate and sponges on the plate to repeatedly squeeze the inner wall of the tank. The porous structure of the sponges facilitates air entry, thus better generating foam. Once sufficient foam is generated, the hydraulic cylinder is closed and the motor is started, causing the two sponges to rotate synchronously. The two sponges work together to effectively clean the inner wall of the tank. The lid is then opened to drain the foamy water from the tank. This cleaning process is repeated three times to ensure thorough removal of residual foam.
