  • Methods of aseptically transporting bulk quantities of sterile products
    Patent number: 6277328
    Abstract: Methods of aseptically transporting a bulk quantity of a sterile product such as an edible food product comprise sterilizing a transporting container by flooding the container with a chemical sterilant, pressurizing the sterilized container with a positive pressure inert gas atmosphere, and aseptically supplying a bulk quantity of the sterile product to the sterilized container. The pressurized container supplied with the sterile product is sealed to substantially maintain the positive pressure during transport of the container, and the container with the sterile product therein is then transported to a remote location. A transporting container for use in the present methods comprises an insulated transportable storage tank provided with a sealable atmospheric vent on an upper portion thereof, an inert gas valve provided with a microbial filter, and an aseptic inlet/outlet valve for supplying a sterile product therethrough.
