  • Patent number: 6112647
    Abstract: A high speed food processing machine providing an improved platen mechanism wherein the device produces more uniform platen pressure across the platens by having multiple hydraulically operated pressure points on the upper platen. The food processing machine is capable of having two belts; one around each platen, to provide more uniform pressure. This uniform pressure allows better heater placement and control. This invention also provides a method of cooling across the platens and removeably attaching the moving belt(s) to the moving platens. An energy storing mechanism assists in the platen movement.
