Claims14
A trouble recovering method of an aseptic filling machine that fills a sterilized content into a sterilized bottle in an aseptic atmosphere and seals the bottle with a sterilized sealing member, the aseptic filling machine having a chamber that shields a heating portion that heats a preform, a molding portion that molds the heated preform into the bottle, a bottle sterilizing portion that sterilizes the bottle, a filling portion that fills sterilized content into the bottle, a sealing portion that seals the bottle filled with the content and a discharge portion that places the sealed bottle on a discharging conveyor constituting the aseptic filling machine, wherein:
- when a trouble occurs in any of the portions, an operation of the aseptic filling machine is stopped, and in a state where an internal pressure of a trouble non-occurrence chamber which is the chamber that shields the portion in which the trouble does not occur is made a positive pressure by supply of an aseptic air, a door of a trouble occurrence chamber that shields the portion in which the trouble occurred is opened, the trouble is removed and then, the door of the trouble occurrence chamber is closed and the inside of the trouble occurrence chamber is sterilized and then, the operation of the aseptic filling machine is resumed,
- wherein if the trouble occurrence chamber is the chamber that shields the filling portion, the sealing portion and the discharge portion, a cleaning of the trouble occurrence chamber is performed, a sterilizer is sprayed into the trouble occurrence chamber, an aseptic water is sprayed and a heated aseptic air is supplied into the trouble occurrence chamber.
