Aseptic filling apparatus and method for cooling filling valve of aseptic filling apparatus
A filling valve that has a high temperature due to an SIP is cooled in a short time. An aseptic water is blasted to an outer surface of the filling valve.
1. A method for cooling a filling valve of an aseptic filling apparatus, the aseptic filling apparatus filling a sterilized container with a sterilized content in an aseptic atmosphere and sealing the container filled with the content,
wherein, when a temperature of the filling valve is equal to or lower than 120° C. by supplying an aseptic air to a content supply pipe, an aseptic water is blasted to an outer surface of the filling valve that has a high temperature due to SIP that is performed before an operation of the aseptic filling apparatus, after the filling valve has a temperature equal to or less than 90° C. by blasting the aseptic water, blasting of the aseptic water is stopped, and the filling valve is further cooled by aseptic air at a room temperature that is supplied into a filling portion chamber where the filling valve is provided.
