[0002] In the food industry, paper roll forming packaging systems are widely used in various aseptic liquid foods. For example, aseptic packaging of juice, beverages, milk and other foods. The main working procedures of the aseptic packaging system of paper roll paperboard bag making are: generation of aseptic air → sterilization of the machine → sterilization of packaging materials → forming of the bag → filling, sealing and cutting. One of the key links is the sterilization of the packaging materials.

[0003] At present, when sterilizing packaging materials, the packaging materials are usually continuously conveyed to a sterilization tank for immersion sterilization through a conveying mechanism. However, some impurities are likely to remain in the sterilization tank during immersion sterilization, and since the packaging materials are continuously input and output with the conveying mechanism, during output, they will drive these impurities to flow toward the outlet of the sterilization tank, and since some impurities are lighter, they will also float above the liquid surface of the sterilization tank, resulting in a large amount of impurities remaining at the outlet of the sterilization tank, causing the outlet to be blocked, and the impurities are likely to accumulate and adhere to the packaging materials, causing contamination of the packaging materials.
