ABSTRACT:
An improved, slide plate-type patty forming apparatus (20) is provided which preferably includes a reciprocating slide plate (60) with a removable, multiple piston and cavity head (78) adapted to move between a retracted meat-filling position wherein respective patty forming cavities (90) are filled with meat to an extended patty-discharging position wherein formed meat patties (264) are ejected. Each of the patty forming pistons (96) is equipped with a porous bottom plate (104) formed of sintered metal or ceramic, an appropriate compressed air passageways (120, 122, 106) are provided for delivery of air through the bottom plate (104) for cleanly ejecting the formed patty (264). Adjusting mechanism (26) for altering the thickness of formed patties (264) includes a plurality of adjusting units (166) each equipped with a vertically shiftable, piston-engaging foot (176); movement of the feet (176) in unison is effected by means of handwheel (164) and connecting gear train (162, 200, 194, 192, 174). Individual variance of respective patty forming stations can also be accomplished by gear disengagement and manual adjustment.
