  • Patent number: 3983260
    Abstract: A method and apparatus for processing food which significantly reduces the time required for cooling. A stream of water is directed onto selected metal lids of jars without risking breakage thereof, while at the same time eliminating the need for an air compressor to maintain the pressure within the pressure cooker during cooling. Pressure within the jars is reduced before or at the same time as the pressure of the steam in th pressure cooker, thus preventing loss of liquid from the jars. The lids are securely sealed to the jars as the jars complete their cooking cycle.
