Description

Technical Field

[0001] The invention relates to the technical field of filling control, and in particular to an aseptic cold filling control method and system based on PET bottled beverages. Background Art

[0002] At present, PET bottles are widely used in beverage production and other fields due to their light weight, good preservation, heat resistance and pressure resistance. However, due to their material characteristics, PET bottles cannot withstand the high temperature of the pasteurization process. PET bottled beverages need to be cold-filled, which results in the sterilization cost of PET bottled beverages being higher than that of glass bottles. The sterilization steps need to be strictly controlled during the cold filling process of PET bottled beverages.

[0003] The existing aseptic cold filling method for PET bottled beverages usually adopts a wet sterilization process, in which a large amount of disinfectant is used to batch spray or soak the PET bottles for disinfection. Due to the bottle body structure of the PET bottle and the aseptic requirements of cold filling, it is necessary not only to spray the disinfectant inside the bottle for sterilization, but also to sterilize the bottle body outside the bottle in all directions. Filling is not allowed until the total colony count of the PET bottle reaches the aseptic filling standard. However, since PET bottles are often sterilized in batches during high-speed transportation, a large amount of disinfectant needs to be wasted to meet the disinfection speed of the PET bottles. Therefore, there is room for further optimization of disinfectant recovery in the aseptic cold filling process of PET bottle beverages. Summary of the invention

[0056] Specifically, before the packaging materials and filling equipment of PET bottled beverages are filled, the colony counts of the packaging materials and filling equipment of PET bottled beverages are randomly sampled and tested, the concentration of the disinfectant is configured according to the original colony count, and after disinfection with the disinfectant, the colony counts on the packaging materials and filling equipment are tested again to obtain the changes in the colony counts before and after disinfection and the corresponding changes in the concentration of the disinfectant. When the colony counts of the packaging materials and filling equipment after a single disinfection reach the standard for aseptic filling and the concentration of the disinfectant after disinfection is also within the standard disinfectant concentration range, it means that the current disinfectant has a good disinfection effect and meets the requirements of aseptic disinfection.

For example, the air is filtered at multiple levels until the air in contact with the filling equipment reaches the sterility standard, and the packaging materials are disinfected at multiple levels until the packaging materials reach the preset sterile filling standard. The multi-level sterilization data of each consumable are summarized to obtain the hierarchical sterilization data of each consumable.

[0079] S402: When the hierarchical sterilization data of each consumable reaches the aseptic filling standard value, the packaging material, liquid material and filling equipment are controlled to perform coordinated cold filling processing to obtain the aseptic cold filling control data of the PET bottled beverage.
