Inverted bottle sterilization machine is a special matching device developed and researched according to the process characteristics of the high-temperature filling production line. The device will roll the product after filling and capping, use the high temperature of the product, and perform secondary sterilization of the cap in a certain period of time to ensure the quality of the product. During the conveying process, the product is guided by two mutually perpendicular chain plates, which implements automatically such operations as bottle inversion, time-delay sterilization, and automatic erection. The whole process is stable and reliable.
