Abstract: High meat content extruded pet s foods and methods of preparation thereof, preferably include initial treatment of a high moisture meat slurry to create a dewatered meat fraction and a liquid fraction. The liquid fraction is directed to an extruder, along with typical dry pet food ingredients, in order to create an extruded intermediate. This intermediate is then mixed with the dewatered meat fraction, and the mixture is then extruded and dried to create a final pet food. The methods may be carried out using separate processing systems each including a mixer, an extruder, and a drying assembly, in order to maximize production rates.

Abstract: Extrusion processes for the production of retort-stable feed products comprise forming a mixture of feed ingredients and subjecting the mixture to specific mechanical energy (SME) and specific thermal energy (STE) inputs to achieve low SME/STE ratios, followed by retorting of the extruded products. The extrusion system (20) includes a preconditioner (22), extruder (24), and a two- stage drying assembly (26/28). The extruded products may be retorted directly from the extruder or after partial or complete drying thereof.

Abstract: A meat dewatering assembly (10) includes a support frame (12), a twin screw dewatering unit (14), a drive assembly (16) coupled with the unit (14), and a perforated housing (60). The unit (14) has a pair of tapered, non-parallel, intermeshed, helically flighted screws (52, 54) presenting nip clearances (59) between the flighting (55). The drive assembly (16) serves to counter-rotate the screws (52, 54). In use, emulsified meat is passed into the housing (60) during counter-rotation of the screws (52, 54), in order to compress the meat within the clearances (59) and thereby express water from the meat. Adjustment collars (38) permit selective size alteration of the nip clearances (59).

Abstract: High meat content extruded pet feeds and methods of preparation thereof, make use of relatively high meat contents which include quantities of previously dewatered meat. In an embodiment, the total meat content of the feeds consists essentially of dewatered emulsified poultry meat or other meat sources commonly used in the pet food industry. In the methods, mixtures containing starch, fat, and meat, the latter including dewatered meat, are passed through an extruder followed by staged drying. The extruder may be of twin screw design having hollow core screws permitting introduction of steam or other heat exchange media into the screws.

Abstract: High thermal transfer, hollow core extrusion screws (50, 52, 124, 126, 190) include elongated hollow core shafts (54, 128, 130, 192) equipped with helical flighting (56, 132, 134, 194) along the lengths thereof. The flighting (132, 134, 194) may also be of hollow construction which communicates with the hollow core shafts (54, 128, 130, 192). Structure (88, 90) is provided for delivery of heat exchange media (e.g., steam) into the hollow core shafts (54, 128, 130, 192) and the hollow flighting (132, 134, 194). The flighting (56, 132, 134, 194) also includes a forward, reverse pitch section (64, 162, 216). The extrusion screws (50, 52, 124, 126, 190) are designed to be used as complemental pairs as a part of twin screw processing devices (20), and are designed to impart high levels of thermal energy into materials being processed in the devices (20), without adding additional moisture.

Abstract: 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.
