The invention relates to an extrude unit for a dryer (2) for biomass, in particular slurry, wherein the extruder unit (1) has a surface section (4) for the biomass to pass through and a plurality of apertures (3), wherein the extruder unit (1) comprises a base support (5) which is connected by means of a connecting section (6) to a driving element (7) and can be driven by means of the driving element (7) about an axis of rotation (8) and relative to the surface section (4), wherein the base support (5) comprises at least one support arm (9) having at least one scraper blade (10) which during a rotation of the base support (5) follows the shape of the face of the surface section (4) facing the scraper blade (10). According to the invention the base support (5) also comprises at least one breaker element (11) having at least one scraper blade (10) which during a rotation of the base support (5) also follows the shape of the face of the surface section (4) facing the scraper blade (10) and during the rotation of the base support (5) effects a crushing of constituents contained in the biomass which are retained by the surface section (4). The invention further relates to a dryer having at least one corresponding extruder unit.

A breathing circuit component includes an inlet, an outlet and an enclosing wall. The enclosing wall defines a gases passageway between the inlet and the outlet. At least a region of the enclosing wall is formed from a breathable material that allows the passage of water vapor without allowing the passage of liquid water or respiratory gases. The breathing circuit component may be the expiratory limb of a breathing circuit.

A method is disclosed for continuously manufacturing a composite hollow structure. The method may include continuously coating fibers with a matrix, and revolving matrix-coated fibers about a non-fiber axis. The method may also include diverting the matrix-coated fibers radially outward away from the non-fiber axis, and curing the matrix-coated fibers.

A blow-molding machine includes an extruder, a manifold, and at least one die head having a view-stripe spider. The manifold is coupled to the extruder. The die head is coupled to the manifold. The blow-molding machine is configured to form a blow-molded container including a container body and a view stripe using the die head.

A variable extrusion die apparatus includes a first die into which an extrusion material is injected. A second die is coupled to the first die and has an extrusion nozzle having a shape corresponding to a cross section of an extrusion product. A swivel core is rotatably installed in the extrusion nozzle, wherein a cross section of the extrusion nozzle is varied by rotation of the swivel core.

Described herein are apparatuses and methods of creating fibers, such as microfibers and nanofibers. The methods discussed herein employ centrifugal forces to transform material into fibers. Apparatuses that may be used to create fibers are also described. Use of material transfer conduits allows the continuous production of fibers without the need to stop the process to refill the fiber producing device.

Described herein are portable apparatuses and methods of creating fibers, such as microfibers and nanofibers. The methods discussed herein employ centrifugal forces to transform material into fibers. Portable apparatuses that may be used to create fibers are described.

An improved rotary head extruder incorporates an auger system comprising more than one auger to create asymmetrical, substantially cylindrical extruded products having a density within the range of about 3.0 to about 6.0 lbs./cu ft. A wide variety of fine particles such as flour and powder can be successfully introduced into and conveyed within a rotary head extruder to the die assembly, where the materials are cooked to form hard, dense extruded collets with randomly asymmetrical shapes. A transition piece at the downstream end of the augers allows for continuous, uniform flow to the die assembly, where cooking takes place. Using the equipment described, raw materials other than the typically used corn meal are produced, while maintaining the desired bulk density, texture, and crunch of random extruded products.

In a method and a corresponding device for producing an extrudate, starting products are introduced into an extrusion container, heated, and homogeneously intermixed by dual asymmetric centrifugation of the extrusion container. The extrusion container is rotated about a primary rotation axis that extends outside the extrusion container, and is simultaneously rotated about a secondary rotation axis that extends through the extrusion container and is situated at an acute angle with respect to the primary rotation axis. Lastly, the intermixed starting products are jointly extruded from the extrusion container. The method and the corresponding device are particularly suitable for processing small and very small substance quantities.

A rubber extrusion device includes a sensor which detects a deviation from a preset reference position of a rubber extrudate extruded from an extrusion port. Based on this detection data, a control unit provides control for correction of the deviation by adjusting a position of a die relative to a head along a leading end surface of the head or a rotational speed of a screw. A rubber material is mixed and kneaded while being extruded forward by a screw installed inside a cylinder. Resultant unvulcanized rubber is fed into an extrusion flow path and extruded from the extrusion port formed in the die.
