ABSTRACT:
An exit orifice of an outer extrusion port of a coextrusion apparatus for producing a composite doughy rope-like extrudate product has a D-shaped cross-section with a straight boundary line or edge located at an upstream side of the exit orifice relative to the direction of motion of a conveyor for taking up and transporting the extrudate product. The D-shaped cross-section of the exit orifice results in an extrudate product having on one side a flat surface which engages the surface of the conveyor upon deposition of the product thereon. An inner extrusion port recessed by a distance from the outer extrusion port has an exit orifice with a substantially oval cross-section taking the form of a pair of semicircular end portions joined by a rectangular central portion. The cross-sections of the exit orifices are elongated in a direction extending parallel to the direction of motion of the conveyor. The outer extrusion port has a D-shaped edge for causing the tumbling of particles in an outer doughy mass extruded between the inner and outer extrusion ports. The outer extrusion port has a land surface extending parallel to the direction of extrudate flow for peeling off dough surface layers adhering to particles tumbled partially through the outer surface of the extrudate mass.
