APPARATUS AND METHOD FOR IMPROVING THE DIMENSIONAL QUALITY OF EXTRUDED FOOD PRODUCTS HAVING COMPLEX SHAPES

摘要

The present invention comprises an improved extruder die assembly (800) and method for using same to improve the quality of dimensional design aspects of extruded, complexly shaped, direct expanded food products. The improved system includes an improved die assembly (800) comprising a first die (810) and a second die (860) having at least one orifice. A majority of the total pressure drop occurs in the first die (810) to pre-expand the dough prior to the dough entering the second die (860). The orifices in the first die (810) can be individually configured to obtain differing dough flow speeds resulting in a desired flow pattern. A plurality of extruded dough ropes formed at each orifice exit of the first die (810) can meld together in the bore and exit the second die. Color or flavor can be added at the first die (810) to enhance the food product.
