description Improved preconditioners (10) are provided for partial moisturization of human food or animal feed ingredients prior to downstream final processing thereof in an extruder (56) or pellet mill. The preconditioner (10) preferably includes an elongated housing (12) having a wall (14) with an inlet (20) and an opposed outlet (22). The housing (12) also has a larger diameter end wall (16) proximal to the inlet (20), a smaller diameter end wall (18) proximal to outlet (22), and a progressively converging housing wall (14) with a taper angle of from about 2-9°. A shaft (36) extends along the length of housing (14) and supports a plurality of outwardly extending mixing elements (46) positioned in axially and circumferentially spaced relationship along the length of the shaft (36). The outer margins (54) of the mixing elements (46) cooperatively define a taper along the length of the housing wall (14). The shaft (36) is designed to operate at high rotational speeds, and the mixing elements (46) may be selectively angularly oriented to retard or increase the flow rate of materials through the preconditioner (10). The simplified preconditioner (10) is operable to provide high degrees of moisturization and precooking.
