ABSTRACT:
The disclosed machine is adapted to separate meat and other soft components from bone and other relatively hard components of meat, fish and other food materials, pieces of which are dumped into a hopper containing a pair of overlapping, oppositely rotating left and right hand feed screws for feeding the pieces into overlapping pump bores in a pump casing. The pump bores are provided with oppositely rotating left and right hand pump screws for pumping the pieces along the bores to develop pumping pressure, whereby the pieces are forced into a hollow separator casing having a tubular tapering separator screen with a multiplicity of perforations therein. A tapered pressure auger is rotatable in the screen for pressing meat and other soft components through the perforations while transporting bone and other hard components past the screen to a discharge device for discharging the hard components while maintaining pressure in the separator casing. The discharge device may grind up the hard components and discharge through a restricted annular orifice. The machine may include a pair of oppositely rotating, closely spaced disjointer screws of the same hand, disposed ahead of the feed screws, for disjointing neck bones and the like, while supplying the disjointed bones to the feed screws. The pump screws may have tapered exit ends affording increased clearance to reduce the buildup of pump pressure.
