  • Thermal processing method and apparatus for use with packaging containers
    Patent number: 5857312
    Abstract: A process for thermally treating a product in a container having a headspace above the product, in which the container is subjected to a heated or cooled environment and is simultaneously agitated. The acceleration to which the container is subjected by the agitation is of sufficient magnitude to cause the process to operate in a regime in which the heating or cooling time required for the product to reach a predetermined temperature is very substantially reduced and moreover is substantially insensitive to changes in the acceleration.
