Abstract
Official abstract text for this publication.
In the COP treatment and the SOP treatment of the interior of a chamber of an aseptic filler, any cleaning liquid or aseptic water remaining in the chamber is quickly removed before spray of a sterilizer containing peracetic acid or hydrogen peroxide. A transfer device for transferring a container in the chamber of the aseptic filler is driven to remove the cleaning liquid sued for the COP treatment or the aseptic water used for the SOP treatment.

The invention claimed is: 1. A method for sterilizing an interior of an aseptic filler chamber before operation of the aseptic filler, the aseptic filler filling a sterilized container with a sterilized content in an aseptic atmosphere and sealing the container filled with the content, wherein after the interior of the chamber of the aseptic filler is cleaned by spraying a cleaning liquid into the chamber, spindles of the cappers are moved up and down to remove any of the cleaning liquid remaining on bellows protecting the spindles, and a sterilizer is then sprayed into the chamber of the aseptic filler. 2. The method for sterilizing an interior of an aseptic filler chamber according to claim 1 , wherein the sterilizer contains hydrogen peroxide. 3. The method for sterilizing an interior of an aseptic filler chamber according to claim 1 , wherein the sterilizer contains peracetic acid. 4. The method for sterilizing an interior of an aseptic filler chamber according to claim 1 , wherein the cleaning liquid is aseptic water. 5. The method for sterilizing an interior of an aseptic filler chamber according to claim 1 , wherein when driving a transfer device, heated aseptic air is blown into the chamber of the aseptic filler. 6. The method for sterilizing an interior of an aseptic filler chamber according to claim 2 , wherein the cleaning liquid is aseptic water. 7. The method for sterilizing an interior of an aseptic filler chamber according to claim 3 , wherein the cleaning liquid is aseptic water. 8. The method for sterilizing an interior of an aseptic filler chamber according to claim 2 , wherein when driving a transfer device, heated aseptic air is blown into the chamber of the aseptic filler. 9. The method for sterilizing an interior of an aseptic filler chamber according to claim 3 , wherein when driving a transfer device, heated aseptic air is blown into the chamber of the aseptic filler. 10. The method for sterilizing an interior of an aseptic filler chamber according to claim 4 , wherein when driving a transfer device, heated aseptic air is blown into the chamber of the aseptic filler.
