The present invention comprises an improved extruder die assembly 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 comprising a first die
and a second die having at least one orifice. A majority of the total
pressure drop occurs in the first die to pre-expand the dough prior to
the dough entering the second die. The orifices in the first die 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 can meld together in the bore and exit
the second die. Color or flavor can be added at the first die to enhance
the food product.
