摘要： Improved extruders and methods for the extrusion cooking of comestible products such as human foods or animal feeds are provided wherein the products may be produced with very low specific mechanical energy (SME) inputs as compared with conventional processing. The methods preferably involve introduction of very high levels of steam into the extruder barrel (12) during processing, which concomitantly reduces necessary SME inputs required to achieve desired cook and expansion levels in the products. In accordance with the invention, fully-cooked pet foods can be fabricated with SME inputs of up to about 18 kWhr/T, whereas aquatic feeds can be fabricated with SME inputs of up to about 16 kWhr/T. In preferred forms, the extruder (10) includes specially configured, intermeshed extrusion screws (18, 20) and a plurality of obliquely oriented steam inlets (48, 50), and an upstream, dual-shaft preconditioner (90) is used having individual variable frequency drives (98, 100) which allow infinite variablility in the speed and rotational direction of the preconditioner shafts (94, 96).

摘要： Screw assemblies are provided for cooking extruders characterized by operation using significantly reduced specific mechanical energy inputs, wherein the screw assemblies include 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 an intermediate section of greater pitch length. The intermediate section has an axial length greater than about four times the length of the axially spaced apart sections. The screw assemblies permit incorporation of significantly greater amounts of steam into comestible products during cooking thereof, as compared with prior art designs.

摘要： An improved, dual-shaft preconditioner (10, 70, 102) is provided having independent drive mechanism (18, 20, 78, 80) operatively coupled with a corresponding preconditioner shaft (14, 16, 74, 76, 106, 108) and permitting selective rotation of the shafts (14, 16, 74, 76, 106, 108) at rotational speeds and directions independent of each other. Preferably, the speed differential between the shafts (14, 16, 74, 76, 106, 108) is at least about 5:1. The mechanisms (18, 20, 78, 80) are operatively coupled with a digital control device (60) to allow rotational speed and direction control. Preferably, the preconditioner (10, 70, 102) is supported on load cells (62, 100) also coupled with control device (60) to permit on-the-go changes in material retention time within the preconditioner (10, 70, 102). The preconditioner (10, 70, 102) is particularly useful for the preconditioning and partial gelatinization of starch-bearing feed or food materials, to an extent to achieve at least about 50% cook in the preconditioned feed or food materials.

摘要： 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.
