  • Publication number: 20200165115
    Abstract: An aseptic filling machine capable of performing molding and filling at the same time that has a compact facility size, requires a reduced initial investment, requires a reduced running cost because of its simplified process, and ensures an aseptic condition with reliability, and an aseptic filling method therefor. An aseptic filling machine includes a pre-heating sterilizing portion that sterilizes a preform, a heating portion that heats the sterilized preform, a molding and filling portion that fills the heated preform with a sterilized content under high pressure, thereby molding the preform into a bottle and at the same time filling the preform with the content, and a sealing portion that seals the bottle filled with the content. Before the aseptic filling machine starts operating, each portion is sterilized. During operation of the aseptic filling machine, aseptic air is supplied to each portion to maintain the aseptic condition.

  • Publication number: 20200148522
    Abstract: A sterilization process transition method of switching from an SIP process to a product sterilization process in an apparatus including piping that feeds a product into a filling machine through a heating sterilization part. The process sterilizes the piping before a filling operation, and the product sterilization process sterilizes the product to be filled. An F value is calculated from temperature and flowrate data on a fluid flowing in the heating sterilization part that are obtained from temperature sensors and flowmeters disposed in the product filling apparatus at predetermined time intervals. The temperature and flowrate at two or more predetermined positions in the product filling apparatus are adjusted from a set temperature and a set flowrate for the SIP process to a set temperature and a set flowrate for the product sterilization process while preventing the F value from becoming lower than a predetermined value.
