This sterilization machine is a customized laboratory equipment that can simulate processes such as ultra-high temperature instantaneous sterilization and pasteurization for juice, dairy products, etc. The sterile canned samples can achieve commercial sterility. This equipment can be combined with previous homogenization and aseptic filling to form a micro production line, which can achieve homogenization, ultra-high temperature instantaneous sterilization, pasteurization, aseptic filling, and simulate the production of sterilized milk, yogurt, juice, enzyme drinks, etc. $r $n fully simulates the industrial production state. $r $n The equipment structure is compact and self-contained. The $r $n peripheral only requires tap water, electricity, and compressed air. The minimum feeding amount for $r $n is 3-5 liters
