Abstract
A method of making an extruded food product from plastic food material by forcing the food material into the depression of a roll that is positioned within an extruder head of an extrusion device and is juxtaposed in closely spaced-apart relationship to an elongated aperture in an extrusion die with the axis of the roll substantially parallel to the long axis of the aperture, the 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 the roll, the depth of the depression with respect to the circumference of the roll being greater at each point along the leading edge than at the circumferentially corresponding point on the opposite trailing edge of the depression; and rotating the roll in a predetermined direction such that as the depression moves past the aperture, the leading edge passes the aperture before the trailing edge, thereby extruding the food material through the aperture to form an extruded food product having uniform dimension and configuration.
