Abstract
A hopper for material such as meat or the like includes a material holding cavity having a substantially centrally located discharge opening. A rotatable shaft is provided in the bottom of the hopper. The shaft is provided with first and second end portions, each of which has spiraled flighting for moving material within the hopper in opposite directions toward the central discharge opening. A disruptor bar is disposed on the central portion of the shaft for intermittently disrupting the concentration of material adjacent the discharge opening and for forcing the material into the discharge opening.
