Abstract: An extrudable food product is provided by a food cooker extruder (12) and is mixed with an additive to form a patterned food product, using a pattern forming die (20, 220). The cross-sectional area of the patterned food product is reduced from an inlet end (34) to an outlet end (36) by a factor of at least 50:1 at an average convergence angle of ≦45° while maintaining the cross-sectional pattern to form a reduced cross-sectional patterned dough, and then is extruded through a die port (13) having an opening equal to the reduced cross-sectional area to form a complexly patterned extrudate. The food product comprising, multiple extrudates are simultaneously formed with the flow rates for each extrudate being adjustable by an adjuster plug (16) including a smooth cylindrical portion (86) extendable into a passageway (14) having a circular cross section of a larger diameter than the cylindrical portion (86).

Abstract: Apparatus and methods are disclosed where plastic extrudable food product is provided such as by a food cooker extruder and is mixed with an additive to form a patterned food product, such as by a pattern forming die. The cross-sectional area of the patterned food product is reduced from an inlet end to an outlet end by a factor of at least 50:1 at an average convergence angle of <45.degree. while maintaining the cross-sectional pattern to form a reduced cross-sectional patterned dough, and then is extruded through a die port having an opening equal to the reduced cross-sectional area to form a complexly patterned extrudate.
