  • Process and apparatus for making meat analogs
    Patent number: 5607710
    Abstract: There is provided a method and apparatus for forming meat analog products and for texturizing a doughmass wherein the ingredients are mixed, passed through a conduit having a decreasing cross-sectional area while the doughmass is heated therein, the heating being done such that a greater heat intensity is applied to the center of the doughmass than to the doughmass adjacent the walls of the conduit.
    Type: Grant
    Filed: February 21, 1996
    Date of Patent: March 4, 1997
    Inventors: Peter W. De Ruyter, Noel Almey, Josef Slanik, Wesley W. Teich

  • Apparatus for making a meat analog
    Patent number: 4346652
    Abstract: The present invention provides an apparatus for texturizing protein products; the apparatus includes a screw conveyor through which a protein dough containing a heat coagulable protein is passed with the conveyor having an internal conveying section changing in configuration such that the dough is stretched during passage through the conveyor, while being heated to a temperature above the heat coagulation temperature of the protein to provide a meat-like fiber structure wherein the fibers are aligned.

  • Method for making a meat analog
    Patent number: 4125635
    Abstract: The present invention provides a process and apparatus for texturizing protein products wherein a protein dough containing a heat coagulable protein is passed through a screw conveyor that has an internal conveying section which changes in configuration such that the dough is stretched during passage through the conveyor, while at the same time is heated to a temperature above the heat coagulation temperature of the protein to ultimately provide a meat-like fiber structure wherein the fibers are aligned.
