Method for achieving aseptic conditions in beverage
The establishment and maintenance of the aseptic environment inside the beverage machinery and equipment, in the aseptic water rinsing, aseptic material filling and capping equipment, according to the cleanliness requirements of different areas, set different positive air pressures, that is, high cleanliness requirements The air pressure in the area is greater than the area with low cleanliness requirements, so that potentially contaminated air will not enter the aseptic space with high cleanliness requirements. Aseptic processing of packaging. The current sterilization methods used for aseptic filling bottles include: spray method, spray method and perfusion method. Because 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. The lid is sterilized by the disinfectant spray method with high sterilization reliability, and there is 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 sterility requirements are met.
