摘要： High Specific Mechanical Energy extruder screw assemblies (14, 88, 98) and complete extruders (10, 86, 96) are provided, which include wide-flight intermediate screw sections (104) having axial flight widths greater than the flight widths of the inlet and outlet screw sections (102, 106) on opposite sides of the intermediate sections (104). The intermediate sections (104) provide increased friction and shear serving to enhance the SMEs imparted to comestible food materials during processing thereof.

摘要： 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 fighting (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).

摘要： High thermal transfer, hollow core extrusion screws (50, 52, 124, 126, 190) include elongated hollow core shafts (54, 128, 130, 192) equipped with helical fighting (56, 132, 134, 194) along the lengths thereof. The fighting (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 fighting (132, 134, 194). The fighting (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.

摘要： An improved, high-capacity die assembly (10) for a food or feed extruder (12) is provided and is particularly useful for the production of high quality aquatic feeds. The die assembly (10) includes a mount (20), which is secured to the discharge end of an extruder barrel (14), with a plurality of tubular die components (22, 24) coupled with the mount (20). Each component (22, 24) includes wall structure (38) defining an outwardly diverging tubular chamber (40) with a die plate assembly (50) coupled to the outer end of the wall structure (38). A flow diverter element (54) is located within each chamber (40) and has a large diameter end adjacent the assembly (50) and a smaller diameter end closer to the chamber inlet. The assembly (50) has a plurality of openings (52) outboard of the element (54).

摘要： The present invention provides improved apparatus and methods for the monitoring and control of apparatus designed to remove moisture from an initially wet product, such as a continuous dryer (14). The net rate of water removal from the wet product (16) is determined during drying thereof, preferably on a real-time basis. A control assembly (20) is operatively coupled with the dryer (14) and includes sensors (24, 26, 28, 34), which are operatively coupled with a digital controller (38). The controller (38) has a PID controller operable to continuously determine the average net rate of water removal from the product (16).

摘要： A method for extruding a comestible material comprises the steps of passing comestible material into an extruder (100) with rotation of the extruder screw(s) (120, 122) and delivery of fluid comprising steam and water into an opening (114a) of the extruder barrel (104). The fluid delivery step comprises separately directing individual quantities of steam and water into the casing (72) of a static mixing section (54), and blending the steam and water to create a blended mixture, and then delivering the blended mixture into the barrel (114a). The blended mixture is delivered to the barrel opening (114a) by a conveying assembly (84, 86) having a pipe assembly (86) with an outlet in communication with the barrel opening (114a); the pipe assembly (86) and opening (114a) have diameters less than maximum internal diameter of the static mixer casing (72).

摘要： Material processing apparatus (20) includes a housing (22) with a plurality of vertically stacked inverting pan conveyors (42, 44) therein. Each conveyor (42, 44) includes a plurality of conveyor pans (50) traveling between and around aligned front and rear sprocket pairs (90, 92) to define upper and lower conveyor runs (52, 54). Each pan (50) has a perforated base plate (56) presenting a pair of opposed material-supporting surfaces (58, 60). As the pans (50) traverse the sprocket pairs (90, 92), they are inverted, and material (110) carried by the upper run pans (50) is transferred to the lower run pans (50) by passage of the material around and/or between the sprocket pair (90).

摘要： A product-spreading hood assembly (10) for use with a die unit (128) includes a deflector (14) having wall structure defining a product inlet opening (90) and a product outlet opening (92); the deflector (14) is preferably generally frustoconical in shape and is supported by a housing (12). An optional air delivery assembly (16) allows air currents to be directed from the area of the inlet (90) towards outlet (92) to facilitate separation of discrete products. Advantageously, the air currents are delivered in a circumferential fashion about the die unit (128). Use of the hood assembly (10) serves to separate high moisture or “sticky” extrudates, thereby preventing agglomeration thereof.

摘要： An improved dual-shaft preconditioner (10) of simplified design is provided giving increased moisturization and partial cooking of food or feed ingredients. The preconditioner (10) includes an elongated, tapered housing (12) presenting a pair of side-by-side, communicating housing sections (58, 60), with a corresponding pair of converging shafts (20, 22) within the sections (58, 60) and having a series of elongated, outwardly extending mixing elements (24, 26) secured to the shafts (20, 22). The preconditioner (10) is designed for use in a system including a downstream processing device, such as an extruder (146).
