Method for achieving aseptic conditions in beverage machinery
Method for achieving aseptic conditions in beverage machinery For cleanliness requirements, set different positive air pressures, that is, the air pressure in areas with high cleanliness requirements is greater than that in areas with low cleanliness requirements, so that potentially contaminated air will not enter the aseptic space with high cleanliness requirements. Aseptic processing of packaging. The sterilization methods currently used for aseptic filling bottles include: spray method, spray method and perfusion method. Since it is difficult for domestic manufacturers to control the initial contamination degree of the bottle to a lower index, the filling method with higher sterilization reliability is used to sterilize the inside of the bottle, and the outside of the bottle is rinsed and sterilized by spraying. There is sufficient leeway in the retention time to ensure that the commercial sterilization requirements are met. The cap sterilization methods currently used for aseptic filling include: jetting, spraying and ultraviolet irradiation. Sterilize the lid with the disinfectant spray method with high sterilization reliability, leaving sufficient leeway in the sterilization retention time. Sterile treatment of materials and material passages. The materials used for filling are sterilized by ultra-high temperature automatic instantaneous sterilization (UHT) equipment. This method can effectively sterilize the materials, and can also reduce the temperature of the materials for a long time, which causes the flavor of the product to change. It is currently the most versatile The most effective material sterilization method, the sterilization effect can ensure that the commercial aseptic requirements are met.
