초록 ▼

A rotor assembly for extruding randomly shaped food items includes a one-piece finger member. The one-piece finger member reduces the downtime of the extruding machine containing the rotor assembly by reducing the number of parts in the rotor assembly and reducing the adjustment necessary after finger replacement. The proprietary threaded interface between the finger member and the improved extruder machine allows for quick swap out during extruder maintenance.

The extruding machine according to claim 9, wherein the auger screw assembly comprises: a first threaded auger screw and a second threaded auger screw. 11. The extruding machine according to claim 10, wherein both the first auger screw and the second auger screw rotate in the same direction. 12. The extruding machine according to claim 10, wherein both the first auger screw and the second auger screw rotate in opposite directions. 13. The extruding machine according to claim 9, wherein the rotor assembly further comprises: a rotor base configured for releasable attachment to an extruding machine capable of rotating the rotor base about a longitudinal axis;a plurality of cutting assemblies releasably coupled to the rotor base;a die plate releasably coupled to the rotor base, the die plate having a central aperture passing there through; andwherein the one-piece finger member is releasably coupled to the rotor base through the central aperture of the die plate via the quick releasing coupling. 14. The extruding machine according to claim 13, wherein the quick releasing coupling comprises: a threaded interface, having three indexed threaded surfaces; andwherein the threaded interface is multi-indexed and non-continuous. 15. The extruding machine according to claim 14, wherein the threaded interface further comprises: a threaded interface capable of engaging completely in approximately ⅙ of a revolution. 16. The extruding machine according to claim 14, wherein the threaded interface further comprises: a pitch difference between lead angle threading and the rest of the threading. 17. The extruding machine according to claim 13, wherein the die plate is fabricated from stainless steel and surface prepared by bead blasting.
