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.
