  • Publication number: 20040013564
    Abstract: A method for filling a container involves supplying a barrier layer to the inside of a container and irradiating the inside with a high energy ray to form a barrier layer on the inner surface of the container and simultaneously sterilizing the inside and discharging a residual barrier material precursor gas and a by-product gas from the container before or during the filling of liquid food into the container. The method allows the formation of a continuous barrier layer covering edges, gloves, clearances and gaps inside the container. Automatic and effective discharge of a residual barrier material precursor gas and a by-product gas from the container through the filling of liquid food is allowed. The method avoids the necessity of chemical disinfectants through sterilization of the inside of a container by irradiation with a high energy ray and thereafter filling a liquid food in an aseptic state.

  • Patent number: 6656423
    Abstract: A sterile water generator (B) generates a stream of sterile water on demand. A water heater (130) heats incoming, unsterile water to a sufficient temperature to achieve sterilization of the water. The sterile water is then passed through a heat exchanger (110) which transfers excess heat from the sterile water to the incoming water. This reduces the energy consumption of the water heater and reduces the temperature of the sterile water ready for use. The sterile water is delivered to a site (A), at which the water is to be used, through a sterile water delivery pathway (C) to avoid recontamination of the water. A first portion (162) of the pathway is pre-sterilized by flowing steam or hot water, generated by the water heater, along the pathway (C). A second portion (212) of the pathway is sterilized with a liquid antimicrobial from the site. The first and second portions of the pathway have at least one common leg (164).
