Sterilization process for aseptic filling line

摘要

The present invention discloses a sterilization process for an aseptic filling line. A first pipeline (25) is provided between the high temperature hot water circulation system and the sterile water circulation system. The material circulation system, the high-temperature hot water circulation system, the sterile water circulation system, and the first pipe line (25) are each pre-washed, and then each system is operated and the first pipe line (25) is communicated. In the high-temperature hot water circulation system, after raising the temperature of the high-temperature hot water to the first sterilization temperature, the temperature is kept in the first time zone to obtain sterile high-temperature hot water so as to sterilize the high-temperature hot water. The first pipeline (25) gradually reduces the flow rate of self-sufficient sterile water in the sterile water circulation system as the sterile high-temperature hot water is gradually replenished into the sterile water circulation system, and at the same time, the high-temperature hot water circulation system is at room temperature. Replenish pure water.
