ABSTRACT:
A food patty-forming apparatus for forming food patties from pressurized food product includes a mold plate that is guided to reciprocate longitudinally between a fill position and a discharge position. The mold plate has a cavity that is open to the source of pressurized food product when in the fill position. The cavity is exposed when in the discharge position. A mold pattern having open areas and solid areas is arranged adjacent a first face of the cavity, and indented from a second face. A knockout plunger has open areas corresponding to the solid areas of the pattern and solid areas corresponding to the open areas of the mold pattern. The knockout plunger is shaped to allow the solid areas of the plunger to penetrate into the cavity past the first face of the cavity around the solid areas to displace a patty formed in the cavity.
