A deodorizing method includes a first rinsing step of supplying first rinse water for a first circulation system to a first circulation system () including at least a heat sterilizer () that heats a drink, a chemical circulation step of supplying and circulating a chemical for a first circulation system in the first circulation system (), and a second rinsing step of supplying second rinse water for a first circulation system to the first circulation system (). At the chemical circulation step, the chemical for a first circulation system is heated to a temperature of 70° C. or higher and 150° C. or lower in the first circulation system ().

Deodorizing method

In an aseptic filling apparatus, a CIP of the content filling station is performed after rotation of a wheel in the content filling station is stopped, a COP or SOP of the content filling station is performed while the wheel in the content filling station is rotating immediately after the CIP is completed, an SIP of the content filling station is performed with rotation of the wheel in the content filling station being stopped immediately after the COP or SOP is completed, and one or both of the COP and SOP of the other stations is performed in a predetermined order while wheels in the other stations are rotating in a period from the start of the CIP to the end of the SIP.

Aseptic filling apparatus and method of decontaminating the same

A method of decontaminating an aseptic filling apparatus that includes stations including a content filling station arranged from an upstream side to a downstream side of a flow of a preform or container, and each of the stations is covered by a chamber. The method includes sterilizing the content filling station by performing a CIP and then an SIP or performing an SIP serving also as a CIP of the content filling station, removing a cleaning liquid used in the CIP or SIP, and performing a COP and/or an SOP of the various kinds of stations in a predetermined order. A first SOP using a first sterilizer and a second SOP using a second sterilizer are performed stepwise on the various kinds of stations while the CIP and the SIP or the SIP serving also as the CIP are being performed on the content filling station.

A bottle is conveyed to a filling device without being sterilized by a container sterilizer, and a culture medium is filled inside the bottle by using the filling device. Then, the bottle is capped with a cap using a cap attachment device. Thereafter, whether or not bacteria survive or propagate in the culture medium in the bottle is verified.
