Abstract
An improved patty forming apparatus (20) is provided with a removable piston face plate assembly (150) adapted to be removably coupled to each piston associated with a cavity head (78) and adapted to move between a retracted meat-filling position wherein respective patty forming cavities (90) are filled with patty material to an extended patty-discharging position wherein formed meat patties are ejected; the piston face plate assembly (150) includes three concentrically nested planar plate members (154, 158, 162) having mating sidewalls (170, 178, 230, 250) with air passageways (270-279) formed between the sidewalls for delivery of air from an aperture through the piston center to the patty material-engaging face of the face plate assembly; interference zones (284) formed between the air passageways (270-279) are provided for releasably securing the assembly members (154, 158, 162) together for permitting disassembly for quick cleaning.
