For use in a meat grinding apparatus of the kind comprising elongate barrel means of substantially circular cross-section and predetermined length and provided adjacent at least one of its ends with an axially disposed rotary bearing means and rotary cutter means and with feed hopper means adjacent its other end, a pressure and feed screw means adapted to be rotatably received in said barrel means, said screw means comprising:
- elongate body means of substantially cylindrical configuration provided with a bore extending substantially coaxially therethrough and comprising screw flight means integral with and uninterruptedly extending over said elongate body means in a substantially helical configuration of variable pitch;
- elongate drive shaft means rotatably journalled in said bearing means and extending through said bore and being releasably affixed to said screw means and said rotary cutter means, thereby separating torsional forces acting on said screw means and on said rotary cutter means.
