摘要:
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.

A method and apparatus for cutting a puff extrudate utilizing a first bladed roll and a second bladed roll. The first and second bladed rolls rotate in opposite directions, and work together to cut the extrudate into similarly sized pieces. The blades are positioned on the rolls offset to each other so as to cut the extrudate with a shearing action.

The present invention comprises an improved extruder die assembly and method for using same to impart a distinct colored and/or flavored pattern into an extrudable food mass during the extrusion process while improving the quality of dimensional design aspects of the resulting extruded, complexly shaped, direct expanded food products. The improved system includes an improved extruder die assembly comprising a converging nozzle section having axially aligned ridgelines which gradually project into the bore of the nozzle as the nozzle converges to gradually disrupt the axial flow of an extrudate at specific peripheral points thereby altering the extrudate's velocity profile. By gradually disrupting the axial flow the extrudate in close proximity to the projecting ridgelines in the converging nozzle prior to its extrusion, the dimensional quality of the resulting direct expanded food piece is greatly improved. Moreover, by carefully positioning the capillary channels of the injection section into that portion of the flowing extrudate not affected by the axially aligned ridgelines, a distinct colored and/or flavored pattern may be imparted into the extrudable food mass during the extrusion process while improving the quality of dimensional design aspects of the resulting extruded, complexly shaped, direct expanded food products.
