Apparatus and method for curled extrudate
A shaping assembly for producing a discrete spiral shaped food product includes a die that defines at least one aperture that is centered on an aperture axis. The at least one aperture extends to an aperture exit and allows for the movement of a stream of food mass through the aperture and out the aperture exit. A shaping tool includes at least one slicing blade that is disposed over at least a portion of the aperture exit to slice the stream of food mass into a plurality of food mass portions. A coupling arrangement engages the shaping tool to facilitate rotation of the slicing blade to spin the plurality of food mass portions into a spiral shaped stream of food mass. The slicing blade simultaneously slices and spins the stream of food mass to create the spiral shaped stream of food mass. A crimper is used to cut the spiral shaped stream of food mass into the discrete spiral shaped food products.
