ABSTRACT:
A food patty molding machine has a reciprocating mold plate. A moldable food product is pumped through a fill passage into cavities of the mold plate when the mold plate is in its fill position. A fill plate, interposed in the fill passage immediately adjacent the mold plate, has a multiplicity of fill orifices distributed in a predetermined pattern throughout an area aligned with the mold cavity when the mold plate is in its fill position. The fill orifices define paths through the fill plate, wherein the paths each have an inlet portion that is perpendicular to a fill side face of the mold plate that is connected to an outlet portion that is obliquely angled to a fill side face of the mold plate. A seal-off stripper plate is interposed in the fill passage immediately adjacent the face of the fill plate opposite the mold plate. The stripper plate is movable along a path transverse to the mold plate path between a fill location and a discharge location. The stripper plate has a multiplicity of fill openings aligned one-for-one with the fill orifices as extensions thereof when the stripper plate is in its fill location.
