Abstract: The invention relates an extrusion device (100) for extruding a semi¬finished product made of elastomeric material, comprising an extrusion body (10) extending along a feeding direction (A) and a pump (20) arranged downstream of the extrusion body (10) along said feeding direction (A). The extrusion body (10) comprises a hopper (30) for loading an elastomeric material and an extrusion screw (50) extending along said feeding direction (A) and having an inlet portion (50a) arranged close to the hopper (30) and an exit portion (50b) arranged close to the pump (20). The extrusion body (10) also comprises a motorised roller (40) arranged at the inlet portion (50a) of the extrusion screw (50) and configured to receive the elastomeric material from the hopper (30) and feed it to the extrusion screw (30). The extrusion screw (50) has a length and a diameter such that the ratio between length and diameter is comprised between 4 mm and 8 mm.

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 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).

Abstract: The present invention discloses and describes 3D printers that print 3D objects with acceptable precision and accuracy. Such 3D printers may comprise one or more of: an extrusion core with particularized temperature controls; an extrusion core with particularized filament pathway geometry; an extrusion core with a nozzle that is integral with a heating block; an extrusion core with nozzles of variable orifice-openings; a filament feeding system using smooth-faced-rollers; a build plate with an adhesion-layer for wetting between the extrudate and the adhesion-layer; an alignment-plane for anchoring axis positioning systems to a common plane to minimize tolerance stacking problems; and a single z-axis guide, a mono-rail, for guiding movement of a build plate in the z-axis direction; which may permit use of minimal mechanical fit tolerances between the mono-rail and a complimentary receiving sleeve.

Abstract: A feed section for an extruder machine including a housing having one or more walls defining an interior area within the housing. The feed section includes a shaft mounted to one or more of the walls and a feed roll assembly disposed at least partially in the interior area and pivotally coupled to the shaft for pivotal movement of the feed roll assembly relative to the housing. The feed roll assembly includes a seat portion releasably coupled to a cap portion. The cap portion is pivotally coupled to the shaft for pivotal movement of the cap portion relative to the housing and the seat portion. The feed roll assembly includes a feed roll rotatingly mounted between the seat and cap portions for conveying material to be extruded between an inlet and outlet of the housing.

Abstract: An extruder that can be cleaned more easily. An extruder in which a material is supplied from a supply opening (21) of a circular tube section (20), the material is sent to a conveyance passage while the material on the surface of a feed roller (4) is scraped by a scraper (5) through rotation of a screw (3) and the feed roller (4). The extruder has a feed roller support portion (23) rotatably supporting the feed roller (4) and installed so that the feed roller (4) can open and close the circular tube section (20) in such a way that the feed roller (4) separates from the screw (3) to open the inner space of the circular tube section (20).

Abstract: A blending apparatus is provided, the blending apparatus including: an outer tube; and at least one inner tube disposed inside the outer tube, wherein a distal end, in a lengthwise direction, of the inner tube is located at an intermediate position, in a lengthwise direction, of the outer tube, and the inner tube has plural of through holes in a vicinity of the distal end thereof.

Abstract: A continuous kneading apparatus including: a stationary portion having an internal space where matter is conveyed; a rotary disc member and a screw member which are configured to convey the matter in the internal space; a drive shaft member to which the rotary disc member and the screw member are fixed; and a cooling medium passage through which a cooling medium passes, wherein the cooling medium passage is provided for the screw member which is placed upstream of the rotary disc member with respect to the conveyance direction of the matter, wherein the cooling medium passing in the cooling medium passage is lower in temperature than the matter passing in the internal space, and wherein the matter passes in the internal space while provided with shear force by rotation of the drive shaft member and thus continuously kneaded, and while cooled by the cooling medium.

Abstract: A device for mixing and/or kneading food products. The device includes a container having an inlet, an outlet, and at least one rotary shaft extending substantially in a longitudinal direction of the container. The at least one rotary shaft includes at least one tool, the at least one tool including at least one bar connected to the at least one rotary shaft via spacers. The at least one rotary shaft further includes an operative area to continuously mix and/or knead the food products, the operative area extending in a longitudinal direction of the at least one rotary shaft.

Abstract: A blending apparatus is provided, the blending apparatus including: an outer tube; and at least one inner tube disposed inside the outer tube, wherein a distal end, in a lengthwise direction, of the inner tube is located at an intermediate position, in a lengthwise direction, of the outer tube, and the inner tube has plural of through holes in a vicinity of the distal end thereof.

Abstract: An apparatus for the manufacture of fiber-reinforced plastic compositions. The apparatus addresses the disadvantages of previous methods and apparatuses for the manufacture of fiber-reinforced plastic compositions using a plasticizing extruder. Some embodiments of the apparatus may increase and/or better define the fiber content in the plasticate, as well as improve performance in the production of plasticates from fiber fleeces and fiber mats. Embodiments include an apparatus with a plasticizing extruder with adapted geometry of the extruder casing and the corresponding screw elements.

Abstract: The invention is addressed to the problem of providing a method whereby a mixing of bulk material containing fibers (fiber material) and plastic granules for the plasticate extrusion of long fiber reinforced thermoplastics (LFT) will be possible during the melting process with high production outputs and with minimized material content in the extruder system and minimized fiber damage, and to the problem of creating an apparatus with an extruder for the practice of the method, which will have an extruder housing of modified geometry as to the feed opening and the corresponding screw elements, so that the disadvantages described above are avoided.
