Sterilizing technology used for sterile filling production line

Abstract

The invention discloses a sterilizing technology used for a sterile filling production line. A first pipeline is arranged between a high-temperature hot water circulation system and a sterile water circulation system; pre-cleaning is conducted on a material circulation system, the high-temperature hot water circulation system, the sterile water circulation system and the first pipeline, and afterwards, all the systems run and communicate with the first pipeline; in the high-temperature hot water circulation system, when the high-temperature hot water is heated to the first sterilizing temperature, heat insulation is conducted for the first time period, the high-temperature hot water is sterilized, and the sterile high-temperature hot water is obtained; and along with the situation that thefirst pipeline supplements the sterile high-temperature hot water into the sterile water circulation system gradually, the flow of sterile water supplied by the sterile water circulation system in the sterile water circulation system is reduced gradually, and meanwhile normal-temperature pure water is supplemented into the high-temperature hot water circulation system. By means of the sterilizingtechnology used for the sterile filling production line, energy consumption of steam, ice water and tower water used during running of the sterile water circulation system is effectively reduced, andenergy consumption of tower water and ice water at the rear end of the material circulation system is effectively reduced.

Description

technical field [0001] The invention relates to a sterilization process for an aseptic filling production line. Background technique [0002] In the aseptic filling production line, the material sterilizer and the sterile water sterilizer are indispensable supporting equipment, which must be operated at the same time to provide the corresponding processing medium for the aseptic filling machine. [0003] The material sterilizer is used for ultra-high temperature instantaneous sterilization of product materials at 138-140 °C, which can effectively kill E. coli, mold, pathogenic bacteria, etc. The final product can achieve the purpose of long-term transportation and storage, extending the shelf life of beverage products. The aseptic water sterilizer is used in aseptic filling production. The bottles and caps used for beverage packaging are sterilized with disinfectant, and then rinsed with sterile water to ensure that the packaging used before filling and capping the product ...

AI Technical Summary

Problems solved by technology

High-temperature hot water at 50-60°C has a poor cooling effect on materials, and heating a large amount of pure water to the sterilization temperature and then cooling it to the use temperature will consume a lot of pure water and energy
