Claims
- 1. A method of making an extruded food product from plastic food material comprising the steps of:
- forcing said food material into the depression of a roll that is positioned within an extruder head of an extrusion means and is juxtaposed in closely spaced-apart relationship to an elongated aperture in an extrusion die with the axis of said roll substantially parallel to the long axis of said aperture, said roll having at least one depression in the surface thereof, at least one edge of which is a generally axially oriented leading edge and forms an abrupt ridge with respect to the surface of said roll, the depth of said depression with respect to the circumference of said roll being greater at each point along said leading edge than at the circumferentially corresponding point on the opposite trailing edge of said depression; and
- rotating said roll in a predetermined direction such that as said depression moves past said aperture, said leading edge passes said aperture before said trailing edge, thereby extruding said food material through said aperture to form an extruded food product having uniform dimension and configuration.
- 2. A method of making an extruded food product which is corrugated in cross-section from plastic food material comprising the steps of:
- forcing said food material into the depression of a roll that is positioned within an extruder head of an extrusion means and is juxtaposed in closely spaced-apart relationship to an elongated corrugation-shaped aperture in an extrusion die with the axis of said roll substantially parallel to the long axis of said aperture, said roll having at least one depression in the surface thereof, at least one edge of which is a generally axially oriented leading edge and forms an abrupt ridge with respect to the surface of said roll, the depth of said depression with respect to the circumference of said roll being greater at each point along said leading edge than at the circumferentially corresponding point on the opposite trailing edge of said depression; and
- rotating said roll in a predetermined direction such that as said depression moves past said aperture, said leading edge passes said aperture before said trailing edge, thereby extruding said food material through said aperture to form an extruded food product having uniform dimension and configuration.
