Patent ID: 8177542

Claim:
A rotary drive nozzle die machine for use with at least first and second dough extruders comprising: a plurality of rotatable nozzles each having: at least two openings to extrude at least two strands of dough therethrough; a converging inlet in communication with the plurality of rotatable nozzles, the converging inlet having an inlet and an outlet that is smaller than the inlet; a first compression head to direct a first flow of a first type of dough under pressure from the first extruder toward the plurality of rotatable nozzles; a second compression head to direct a second flow of a second type of dough under pressure from the second extruder toward the plurality of rotatable nozzles, wherein the first and second compression heads each have an inlet and an outlet that is smaller than the inlet; a mixing chamber connected to the first and second compression heads downstream from the first and second compression heads and configured to receive the first and second flows of dough from the first and second compression heads, to mix the second dough into the first dough to form a mixed dough and to direct the mixed dough to the plurality of rotatable nozzles, wherein the mixing chamber is directly adjacent to and upstream the converging inlet; and a drive assembly to rotate the plurality of rotatable nozzles wherein the at least two strands of the mixed dough extruded through the at least two openings of the plurality of rotatable nozzles are spiral wound together to form a single dough stream.
