<p>A patty-displacing end portion is provided for a plunger for a food patty-molding apparatus, the apparatus comprising an apparatus frame, a mold plate, the plunger and a heating element. The mold plate has at least one cavity and is mounted to reciprocate with respect to the frame in a longitudinal direction to position the cavity between a rearward, fill position wherein the cavity is filled with food product material to form a molded patty, and a forward, molded patty knockout position. The plunger has a patty-displacing end portion arranged to move vertically into the cavity to knock the molded patty out of the cavity. The heating element is typically arranged to heat the patty-displacing end portion to about 180 to 210°F. The patty-displacing end portion is composed of plastic. Preferably, the patty-displacing end portion is composed of a thermoplastic that retains structural strength up to 210°F such as FDA & USDA approved solid polyester-semi-crystalline polyethylene terepthalate (PET-P) thermoplastic with a uniformly dispersed solid lubricant.</p> |
