| 1. A method of extruding a food material from an extruder barrel, comprising the steps of:
moving said food material under pressure along a progressively diverging, generally frustoconical path of travel defined between
a stationary tubular section having an axial length with an internal bore presenting a smaller diameter inlet end and a larger
diameter outlet end, and an axially rotating, helically flighted screw section within said bore, said diverging path of travel
being at a divergence angle of from about 1-11° in a direction from said inlet end toward said outlet end;
passing said food material from said outlet end toward and through a plurality of restricted orifice die openings so as to
create a pressure drop across the die openings; and
elevating the temperature of said food material during the passage thereof through said barrel, and achieving at least about
75% cook of the food material.
