  • Patent number: 4161909
    Abstract: An ultrahigh temperature heating system is provided for use in obtaining controlled heating of a liquid product. The system includes an upright chamber into which a controlled amount of liquid product flows and then descends through the chamber in a curtain-like pattern. The descending product passes a steam inlet provided in the chamber wall and is intermixed with and heated by a controlled amount of entering steam whereby the temperature of the descending product is increased to a predetermined amount. A pump is connected to an outlet formed in the lower portion of the chamber and removes therefrom the mixture of product, condensate, noncondensable gas, and steam so as to prevent an accumulation therein of said mixture while at the same time maintaining a predetermined pressure within the chamber. The discharge side of the pump is connected to an intermixing means causing all of the steam entrained in the product to condense.

  • Patent number: 4130052
    Abstract: The present invention relates to a method and apparatus for smoking foods. An enclosure is presented which is characterized by an absence of any ventilating means. The enclosure is substantially air tight. Hickory or other exotic wood blocks or chips are used as the source of smoke and an electric heating element raises the temperature in the enclosure to approximately 200.degree.-300.degree. F. This activates the wood and produces the desired smoke. The increase in temperature also produces an increase in pressure within the enclosure which in turn causes a pressure differential between the inside and the outside of any food being processed. This forces smoke and wood resins to permeate the meat and enhance the food with the desired smoke flavor. The enclosure in which the food is smoked is also of unique design in that the back wall is presented in three planes so as to avoid forming any right angles with any other sidewalls.
