Feed screw for meat grinding reclamation system

A meat grinding reclamation system is disclosed herein. The system uses a conical feed screw. The conical feed screw is provided with a shaft and two flights. The first flight changes from a constant diameter to an expanding diameter. The second flight is provided co-helically along the shaft with a portion of the first flight. As both flights expand in diameter, meat processed through the meat grinding reclamation system accelerates, dislodging undesirable material such as gristle from the meat, before the meat decreases in velocity to present the meat for further processing.
