Abstract
In an aseptic filling machine including content supply piping for feeding a content to a filler via a heat sterilization portion, CIP and SIP of the inside of the content supply piping is performed by circulating a cleaning liquid, SIP is performed by heating the cleaning liquid to a required temperature for sterilization from the start of the CIP or during the CIP, the overall heat transfer coefficient of the heating piping is calculated, it is determined that the CIP is completed when the overall heat transfer coefficient calculated reaches a target value, temperatures are measured by a plurality of temperature sensors provided, a lowest temperature is selected from the measured temperatures, F values are calculated for the selected lowest temperature, the calculated F values are accumulated, and it is determined that the SIP is completed when the accumulated F value reaches a target value.
