Abstract
Twin screw cooking extruders are provided requiring reduced specific mechanical energy inputs, through use of screw assemblies including first and second elongated, axially rotatable screws which are substantially coextensive in length, with the screw flighting presenting a pair of axially spaced apart sections of short pitch length and intermediate sections of greater pitch length. The intermediate sections have an axial length greater than about four times the length of the axially spaced apart sections.
