Abstract
The present invention comprises a rotary drive nozzle die machine for use with at least first and second dough extruders. The machine includes at least one rotatable nozzle having at least two openings for extruding at least two strands of dough therethrough, a first compression head for directing a first flow of a first type of dough under pressure from the first extruder toward the at least one rotatable nozzle and a second compression head for directing a second flow of a second type of dough under pressure from the second extruder toward the at least one rotatable nozzle. A mixing chamber is connected to the first and second compression heads for receiving the first and second flows of dough, for mixing the second dough into the first dough and for directing the mixed dough to the at least one rotatable nozzle and a drive assembly rotates the at least one nozzle whereby the at least two strands of the mixed dough extruded through the at least two openings of the at least one nozzle are spiral wound together to form a single dough stream.
