The bottle inverting conveyor chain is a special equipment developed according to the technological characteristics of the juice hot-filling production line. The sealing gasket of the cap is softened to improve the sealing degree between the cap and the bottle body. The sterilizing time is ≥30 seconds. After the sterilization is completed, the conveyor chain will automatically straighten the product and enter the next process. During the conveying process of the high-temperature filled material, the bottle is automatically poured on the bottle-inverting chain through the pouring mechanism of the bottle-inverting chain, so that the bottle cap is continuously in contact with the high-temperature material for a certain period of time, and the high temperature o
