  • Food processing apparatus and method
    Patent number: 5348753
    Abstract: A food processing apparatus comprises a heat exchanger with a food path for connecting a source of food substance to the heat exchanger and a pump located in the food path for conveying food substance from the source to the heat exchanger. A pressure sensor is provided for sensing pressure downstream of the pump and for transmitting a pressure signal corresponding to a measured pressure downstream of the pump. A controller connected between the pump and the pressure sensor controls the pump in response to the pressure signal.
    Type: Grant
    Filed: April 16, 1993
    Date of Patent: September 20, 1994
    Assignee: Besst Frozen Products, Inc.
    Inventors: Edward E. Ahnell, Ernest W. Curry

  • Food processing apparatus and method
    Patent number: 5151288
    Abstract: An apparatus for making a frozen confection product from a liquid food substance comprises a gas port for selectively injecting gas from a pressurized source into the liquid food substance at an injection point to form a mixture, a freeze tube having an inlet end and an outlet end and having a substantially cylindrical wall for containing the mixture therein, a cooling circuit for cooling an external surface of the cylindrical wall, and a whipping auger disposed within the freeze tube for emulsifying the liquid food substance portion of the mixture with the gas portion thereof, the whipping auger propelling a first portion of the mixture in a helical pattern from the inlet end of the freeze tube toward the outlet end and for simultaneously propelling a second portion of the mixture in a direction from the outlet end toward the inlet end of the freeze tube.
