ABSTRACT:
Disclosed are a method and a system for extruding, cut into strands, cooling, and chopping a ground food product. The system comprises a cooling unit, a conveyor belt urging the pieces through the unit, and a chopper for cutting the pieces exiting the unit. A cryogen source provides cryogen to the cooling unit. A feeder feeds the ground food product onto the conveyor belt adjacent an inlet of the unit. The feeder also extrudes the ground food product through a nozzle to place the stranded pieces onto the conveyor belt. A shear plate cuts the stranded pieces, while being extruded. A hydraulic system moves the shearing plate. The system is adapted to dispense cryogen to the cooling region at a rate sufficient to lower the temperature of the cut stranded pieces to a desired temperature when they exit the unit. A chopper cuts the extruded and stranded pieces immediately after freezing.
