ABSTRACT:
An extrusion apparatus includes a housing having parallel top and bottom surfaces and a converging portion and a cooperating diamond-shaped flow bar for aligning fibers during extrusion of a meat dough. The flow bar is disposed in the housing such that trailing faces of the flow bar are parallel to the converging faces of the apparatus and the leading faces of the flow bar converge with the parallel faces of the housing and are spaced therefrom a distance to effect fiber alignment. The flow bar is rotatably mounted within the housing to control and vary the extent of fiber alignment as desired. A discharge nozzle is provided having a constricted portion tapering longitudinally and transversely toward the center of the nozzle to ensure fiber alignment throughout the width of the extruded dough. The extruder is able to effect substantial fiber alignment across a wide extrudate such that when cut into individual pieces, each piece will have a substantial portion of fibers uniformly aligned.
