A cutter assembly for an extruder includes an elongated extrusion member having an open feed end. The open feed end is attachable in fluid communication with a manifold of the extruder for supplying a mash thereto. An extrusion die is supported on the elongated extrusion member. The extrusion die includes a plurality of extrusion outlets formed therein. A cutter member cuts extrudate to a desired length as the extrudate exits the die. The cutter member is slidable on the extrusion member in a direction of elongation of the extrusion member. The cutter member is operably connectable at the drivable end to a drive device of the extruder for reciprocatably sliding the cutting surface of the cutter member over and away from the extrusion die. The shape of the extrusion outlets twist the mash as the mash exits the extrusion die in order to form a twisted food product.

What is claimed is: 1. A cutter assembly for an extruder, comprising: an elongated extrusion member having an open feed end, said open feed end being attachable in fluid communication with a manifold of the extruder for supplying a mash to said elongated extrusion member; an extrusion die supported on said elongated extrusion member, said extrusion die including a plurality of extrusion outlets formed therein; and a cutter member having an open drivable end, an elongated cutter wall, and an open cutter end with a cutting surface for cutting extrudate to a desired length as the extrudate exits the die, said cutter member being disposed at least partially over and reciprocally slidable on the extrusion member in a direction of elongation of the extrusion member, said cutter member being operably connectable at the drivable end to a drive device of the extruder for reciprocatably sliding the cutting surface of the cutter member over and away from the extrusion die, wherein each of said plurality of extrusion outlets is shaped to have at least one wide portion and at least one narrow portion, the shape of the extrusion outlets twisting the mash as the mash exits the extrusion die in order to form a twisted food product. 2. The cutter assembly according to claim 1, wherein each of said plurality of extrusion outlets is in the shape of a polygon having concave walls. 3. The cutter assembly according to claim 2, wherein each of said plurality of extrusion outlets has a maximum height of approximately 0.3 to 0.4 inches and a maximum width of 0.2 to 0.3 inches. 4. The cutter assembly according to claim 1, wherein each of said plurality of extrusion outlets is in the shape of a truncated triangle having concave walls. 5. The cutter assembly according to claim 4, wherein each of said plurality of extrusion outlets has a maximum height of approximately 0.3 to 0.4 inches and a maximum width of 0.2 to 0.3 inches. 6. The cutter assembly according to claim 1, wherein each of said plurality of extrusion outlets is in the shape of an hourglass having concave walls. 7. The cutter assembly according to claim 6, wherein each of said plurality of extrusion outlets has a maximum height of approximately 0.3 to 0.4 inches and a maximum width of 0.2 to 0.3 inches. 8. The cutter assembly according to claim 1, wherein there are two of said plurality of extrusion outlets in said extrusion die. 9. A method of operating an extruder having a cutting member, said method comprising the steps of: providing an elongated extrusion member having an open feed end, said open feed end being attachable in fluid communication with a manifold of an extruder for supplying a mash to said elongated extrusion member; providing an extrusion die supported on said elongated extrusion member, said extrusion die including a plurality of extrusion outlets formed therein, each of said plurality of extrusion outlets being shaped to have at least one wide portion and at least one narrow portion, the shape of the extrusion outlets twisting the mash as the mash exits the extrusion die; providing a cutter member having an open drivable end, an elongated cutter wall, and an open cutter end with a cutting surface for cutting extrudate to a desired length as the extrudate exits the die, said cutter member being disposed at least partially over and reciprocally slidable on the extrusion member in a direction of elongation of the extrusion member, said cutter member being operably connectable at the drivable end to a drive device of the extruder for reciprocatably sliding the cutting surface of the cutter member over and away from the extrusion die; and extruding the mash while twisting the mash to form a twisted food product. 10. The method according to claim 9, further comprising the step of shaping each of said plurality of extrusion outlets in the shape of a polygon having concave walls. 11. The method according to claim 10, further comprising the step of providing each of said plurality of extrusion outlets having a maximum height of approximately 0.3 to 0.4 inches and a maximum width of 0.2 to 0.3 inches. 12. The method according to claim 9, further comprising the step of shaping each of said plurality of extrusion outlets in the shape of a truncated triangle having concave walls. 13. The method according to claim 12, further comprising the step of providing each of said plurality of extrusion outlets having a maximum height of approximately 0.3 to 0.4 inches and a maximum width of 0.2 to 0.3 inches. 14. The method according to claim 9, further comprising the step of shaping each of said plurality of extrusion outlets in the shape of an hourglass having concave walls. 15. The method according to claim 14, further comprising the step of providing each of said plurality of extrusion outlets having a maximum height of approximately 0.3 to 0.4 inches and a maximum width of 0.2 to 0.3 inches. 16. The method according to claim 9, further comprising the step of extruding the mash at a pressure of greater than 100 lbs/in2, and said pressure in conjunction with the shape of the plurality of extrusion outlets twists the mash as the mash exits the extrusion die to form the twisted food product. 17. The method according to claim 9, further comprising the step of extruding the mash at a pressure of greater than 150 lbs/in2, and said pressure in conjunction with the shape of the plurality of extrusion outlets twists the mash as the mash exits the extrusion die to form the twisted food product. 18. The method according to claim 9, further comprising the step of providing two of said plurality of extrusion outlets in said extrusion die.
