Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of decontaminating an aseptic filling apparatus, the aseptic filling apparatus comprising various kinds of stations including a content filling station arranged from an upstream side to a downstream side of a flow of a preform or container, each of the various kinds of stations being covered by a chamber, and the method comprising: cooling a plurality of filling valves by spraying a chemical to the filling valves as a part of an SOP when the SOP of the content filling station is started after a sterilization in an SIP is completed by using a vapor. 2. A method of decontaminating an aseptic filling apparatus, the aseptic filling apparatus comprising various kinds of stations including a content filling station arranged from an upstream side to a downstream side of a flow of a preform or container, each of the various kinds of stations being covered by a chamber, and the method comprising: performing one or both of a COP and an SOP of the various kinds of stations in a predetermined order, wherein 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, and the second SOP uses water of a temperature equal to or higher than 60° C. and lower than 100° C. instead of the sterilizer.
