A method and apparatus for cutting a puff extrudate utilizing a blade that passes through the extrudate while the extrudate is in a viscous melt stage. The present invention utilizes a tube to facilitate production of a curly puff extrudate. A gap is provided in between the tube and the extruder die to allow a blade to access the extrudate as it exits an orifice in the die. The blade accesses the extrudate at the viscous melt stage, before the extrudate has cooled and hardened. The blade nicks the extrudate, as opposed to completely cutting it, which allows the extrudate to remain connected throughout processing such as curling in the containment tube. The gap also allows steam to be vented form the extrudate as it exits the orifice in the die. The nicked extrudate separates when fried or baked.

1. A method of producing a plurality of extrudate pieces comprising:extruding an extrudate such that said extrudate exits an extruder in a plastic melt stage;nicking the extrudate while the extrudate is in the plastic melt stage with a nicking device; andseparating the extrudate into pieces delineated by the area of the nicks in the extrudate using a separation device. 2. The method of claim 1 wherein the nicking device is a blade. 3. The method of claim 2 wherein the blade nicks the extrudate exiting an orifice in a die. 4. The method of claim 2 wherein the blade nicks a plurality of extrudates exiting a plurality of orifices in a die. 5. The method of claim 1 further comprising: processing the extrudate; wherein the extrudate remains connected during processing. 6. The method of claim 5 wherein the processing comprises passing the extrudate through a containment vessel and applying a resistance to the extrudate to produce a non-liner extrudate. 7. The method of claim 6 wherein the nicking device accesses the extrudate through a gap in between a die and the containment vessel. 8. The method of claim 6 further comprising:positioning the containment vessel away from an orifice in a die such that the extrudate does not pass through the containment vessel; andrepositioning the containment vessel in front of the orifice such that the extrudate passes through the containment vessel. 9. The method of claim 6 further comprising:positioning the nicking device away from an orifice in a die of an extruder such that the nicking device does not nick the extrudate; andrepositioning the nicking device in front of the orifice such that the nicking device nicks the extrudate. 10. The method of claim 1 wherein the step of separating said extrudate occurs during a baking step. 11. The method of claim 1 wherein the step of separating said extrudate occurs during a frying step. 12. The method of claim 1 wherein the step of separating said extrudate occurs during a conveying step with a paddle wheel. 13. The method of claim 1 wherein the step of separating said extrudate occurs during a tumbling step. 14. The method of claim 1 wherein the step of separating said extrudate occurs during a conveying step.
