    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: Device for processing material by mixing and/or plasticization or agglomeration A device for processing material by mixing and/or plasticization or agglomeration has a screw housing (6), in which at least two screws (1, 2) are situated adjacent to one another. The screw channels (7) are engaged with one another. The screws are driven to rotate by at least one motor (3). The screws (1, 2) are supplied with the material through an intake opening (39) of the screw housing (6) and the processed material leaves the screw housing through at least one outlet opening (51). An apparatus (19) is provided, which in operation of the device provides the gap (8) which exists between adjacent screw channels (7) of the screws (1, 2) alternately with a periodic enlargement or reduction, which is superimposed on the rotational movements of the two screws (1, 2).In the method for material processing, the material, in addition to the compaction which is caused by the conveyance action of the screws, is subjected to periodic squeezing by the screws.

    摘要: Improved short length extrusion cooking devices (10) are provided which can achieve product throughput and quality characteristics of conventional long-barrel extruders. The short length extruders (10) of the invention include a relatively short barrel (14) having an inlet (18) and an endmost extrusion die (20). An elongated, helically flighted axially, rotatable screw assembly (22) is positioned within the barrel (14) and is coupled to motive structure (39, 39a) for rotation of the assembly (22) at a speed of at least about 500 rpm. The device (10) may include an internal, apertured flow-restricting device (60, 102) which defines a mid-barrel choke point for the material being processed. An alternate extruder (120) is configured without a mid-barrel restriction and is designed to operate at essentially atmospheric internal pressure throughout the majority of the length of barrel (122) with a significant pressure rise in the final head (134) adjacent the extrusion die. Preferably, the barrel (14, 122) has an internal bore of generally frustoconical configuration with an effective length to maximum diameter ratio (L/D) of at least about 6. Novel extrusion processes and products are also provided, using extremely short extrusion barrel retention times to give cooked extrudates having essentially no amino acid or vitamin nutrient losses, and/or dense, highly cooked, low moisture feeds. Twin screw extruders (232, 232a) with and without mid-barrel restriction elements (252-256) can also be provided, and include an internally tapered barrel (237) with correspondingly tapered, flighted, axially rotatable screws (238, 240).

    摘要: A material pusher comprises a cylindrical body, a threaded rod pivotally arranged in the cylindrical body, and a driving device for forcing the threaded rod to rotate. The threaded rod is provided with a circular rod-shaped pivot portion located near the driving device and provided with a pivotally disposed force-feeding element of conical construction having a tapered end facing the free end of the threaded rod to which it is pivotally attached. The force-feeding element and the threaded rod are driven by the driving device to rotate at different speeds.

    摘要: A barrel block for a twin-screw extruder constitutes a barrel including a cylinder and has joints at both ends. A first joint includes a first inner joint face on a peripheral edge of a first hole of an insertion hole for screws, and includes a first flank face and a first outer joint face on an outer periphery of the first inner joint face. The first outer joint face is located in the outer periphery of a plurality of first bolt holes. The first outer joint face is more recessed toward a second block end face than the first inner joint face.
