Beverage label aseptic packaging technology is a kind of packaging technology, which is filled and sealed in a sterile environment under the condition that the packaging object, the object to be packaged and the packaging auxiliary equipment are sterile.
Beverage label aseptic packaging technology makes packaged products without adding preservatives, in normal temperature conditions without refrigeration can keep fresh for more than half a year or 1 year without going bad, but also has low energy consumption, less packaging material consumption, low manufacturing cost, high packaging efficiency, good economic benefits and light quality, as well as waste packaging can be recycled and other advantages, suitable for long-distance transportation.
Beverage labeling aseptic packaging requires that the entire process from food sterilization to aseptic filling to packaging seal should prevent the invasion and contamination of external microorganisms. The various connecting parts through which food flows should be reliably sealed to prevent the food from being contaminated by microorganisms from outside the system. In the process of aseptic packaging, full attention should be paid to the secondary contamination of microorganisms. Minimize the time that sterilized food and packaging containers come into direct contact with air. Aseptic packaging sealing for aseptic packaging is the last link, is also a key link, directly affect the product packaging quality and storage period.
Calculation and control of sterilization of beverage label aseptic packaging products is one of the key technologies for the success of aseptic packaging. Sterilization calculation of aseptic packaging products depends on sterilization temperature and sterilization time. If the aseptic treatment system uses an indirect heat exchanger, in addition to the germicidal value obtained by the product in the holding tube at high temperatures, a certain germicidal value is produced during heating and cooling. The sterilization values of these two parts add up to the sterilization values of the entire sterilization process.
The key technology of beverage label aseptic packaging lies in the sterilization of packaging materials or packaging containers, the acquisition and maintenance of sterility. In order to achieve the above two purposes, it is important to monitor and record the critical control points of aseptic packaging system. Compared with traditional production methods, the task of automatic recording and monitoring in aseptic systems is much heavier, because of the inherent complexity of aseptic packaging technology and the correlation of many key factors.
Strict inspection measures are also an important guarantee to ensure the smooth implementation of aseptic cold filling process. The operation requirements of aseptic filling room are very strict and must be carried out in accordance with the operating procedures. During the filling process, the laboratory personnel must carry out online inspection of the juice aseptic packaging. After the filling machine has just been adjusted, two boxes should be sampled every 10min before pasting on the self-supporting bag to check the molding, sealing and pasting quality and filling capacity; After normal operation, two boxes should be randomly checked every 30 minutes with the same contents.
