摘要： An improved twin screw extruder device (14) is provided which is capable of producing a wide variety of high quality extrudates having greatly varying final properties, without the need for extensive machine modifications. The extruder (14) includes a barrel (16) together with a co-rotating twin screw assembly (22). The assembly (22) is made up of a pair of screws (50, 52) having central, tapered shafts (54, 56) equipped with outwardly extending helical flighting (58, 60); the screws (50, 52) are non-parallel and are positioned so that the flighting (58, 60) thereof is intercalated along the length of the screws (50,52). The flighting is of specialized configuration and tapers along the length of the screws (50, 52) preferably at an angle of taper different than that of the shafts (54, 56); moreover, the width of the outer flighting surfaces (70, 72) increases along the length of the shafts (54, 56). This screw geometry defines a series of alternating upper and lower close-clearance high-pressure nip areas (78) defined by the flighting (58, 60) which serves to propel an extrudable mixture forwardly towards the outlet end (20) of the barrel (16). However, passageways (80) and kneading zones (82) are also defined between the screws (50, 52), which assures full mixing, shearing and cooking of the material. The extruder device (14) is capable of producing high density sinking aquatic feeds as well as expanded, low density products merely by changing the rotational speed of the screws (50, 52) together with appropriate temperature control. In another embodiment, a fluid extraction extruder (138) is provided having a specialized extruder head (140) including an outer shell (144) and an inner, elongated, slotted sleeve (152).

摘要： An improved, low cost, energy efficient extrusion device and method for processing of cellulose, hemicellulose, and like fiber-bearing materials is described which includes a pretreatment extrusion zone and a reaction extrusion zone separated by a pressure sensitive variable die. The method hereof includes the steps of extruding cellulosic material through the pretreatment zone at an elevated pressure and temperature, passing the material into the reaction zone where it is mixed with an acid and is processed at a lower pressure and temperature than in the pretreatment zone, and extruding the material through a final extrusion die. The surging and blowing usually experienced with extrusion of fibrous material is drastically reduced by the unique construction of the extruder die members. The cellulosic material may be hydrolyzed to simple sugars in accordance with the method and apparatus hereof with a minimum of acid degradation of the extrusion equipment. The sugars produced from the cellulosic material may in turn be converted into ethanol or other usable fuels by the process of fermentation.

摘要： A method of producing extrudates such as high protein, high fat sinking aquatic feeds is provided wherein a high protein starting material is initially preconditioned and passed through an extruder; in the extruder barrel a zone of reduced pressure is created upstream of the die for densifying the final extrudate. Fat may be added to the starting mixture at any desired point in the process, and/or may be added as a surface coating to the final extrudate. Preferably, the method further involves measuring a density value of the extrudate such as bulk density, and adjusting the magnitude of the reduced pressure conditions in the barrel in response to such measurement.

摘要： A greatly improved twin screw extruder and method are disclosed which significantly reduce extruder wear through provision of separate, complemental, interfitted frustoconical screw and barrel sections adjacent the outlet end of the extruder barrel which create an even, bearing-type support for the rotating screws as material passes through the apparatus. In preferred forms, the screws are intermeshed along the majority of the extruder barrel, but diverge at the region of the final frustoconical screw sections and are received within respective complemental barrel sections; in this fashion the material being processed is split into juxtaposed, non-communicating streams, and thereby evenly flows around and supports the adjacent screw section to lessen the tendency of the screws to separate themselves and come into wearing contact with the surrounding barrel walls. The extruder can be used to process a wide variety of plant-derived materials, but is particularly useful for viscous substances (e.g., soy concentrates and isolates) which can be difficult to handle with mono-screw extruders.

摘要： Improved, high-capacity processing systems including a processing device such as an extruder (26) or a pellet mill (P) are provided which minimize product losses and permit the user to conduct multiple, segregated short runs with a minimum of down time between runs. The extruder systems (20, 220) include an extruder assembly (21, 221) having a special, multiple-position die assembly (28), as well as an upstream preconditioner (24) and feed bin assembly (22). A variable speed, variable output discharge screw feeder (78) is located between the preconditioner outlet (62) and extruder barrel inlet (90). A PLC-type controller (30) coupled to the extruder assembly components establishes a choke full condition at the discharge feeder (78) so that continuous uninterrupted flow of preconditioned material to the extruder (26) at a uniform mass flow rate is maintained for as long as possible. In preferred forms, load cells (46, 72) are operatively coupled to the bin assembly (22) and preconditioner (24) so as to monitor material flow through the systems (20, 220). A multiple stage cascade-type dryer assembly (29) is provided downstream of extruder (26). The assembly (29) is controlled via the controller (30) in coordination with the extruder assemblies (21, 221) so as to maintain the segregation between separate product runs throughout the drying operation. Pellet mill systems include bin and preconditioner assemblies (22, 24) operatively coupled with a pellet mill (P).

摘要： An improved extruder screw section and barrel assembly is provided which is especially designed for effective extrusion processing of whole or cracked grains or cellulosic materials which can subsequently be converted to alcohol. The overall assembly includes an elongated, tubular head section presenting on the interior thereof at least one relatively sharp cutting edge (preferably in the form of a spiral rib), along with an elongated, axially rotatable screw section disposed within the head section. The screw section is characterized by a series of separate, elongated, circumferentially spaced grooves generally along the length of the section which progressively decrease in depth from one side margin of the grooves to the other, in the direction of screw rotation; thus, the material being processed is, by virtue of screw rotation and the groove configuration, pushed radially outwardly against the cutting edge presented by the surrounding barrel section. In this manner, the material is effectively subdivided or sliced to enhance the cooking thereof and maximize downstream alcohol production. In preferred forms, the screw section grooves are of progressively decreasing width and depth from the input end thereof to the output end, in order to increase the compressive forces on the material along the length of the section.
