摘要: An extruder (20) is specifically designed for the production of animal feed products (e.g., aquatic feeds) containing substantial quantities of low-cost fibrous materials, such as rice byproducts, at high production rates. The extruder (20) includes an elongated barrel (22) with a screw assembly (24) within the barrel and an endmost extrusion die assembly (34). The screw assembly (24) includes an inlet screw assembly (42) and a processing screw assembly (44). The assembly (44) includes screw components (50-56) of differential pitch to present a long pitch inlet section (64) and a tight pitch discharge section (68). Materials passing through the screw assembly (24) are successively subjected to high levels of steam injection (STE) followed by high levels of friction and shear (SME), so that the STE/SME ratio is at least about 6/1.

摘要: A double-screw extruder for thermoplastic materials, with a first and a second extruder screw, whereby the extruder screws have an inlet and an outlet and a core, helically extending screw flights being arranged through the core from the inlet to the outlet, so that the screw peaks and valleys are circumferential, and the peaks of the first screw penetrate into the valleys of the second screw, and vice versa. The screw flights may have a geometry which is step-shaped in cross section, whereby the steps may be provided such that the stepped course of the peaks is congruent with the stepped course of the valleys.

摘要: A seal ring is provided which allows the interior of a cylinder 1 of a screw extruder to be maintained at elevated temperature and elevated pressure, thus suppressing a variation in the pressure in the cylinder 1. In a special seal ring 300 attached to a screw shaft 7 in the cylinder of the screw extruder so as to be rotatable integrally with the screw shaft 7, thus restraining a material to be treated from being fed from upstream to downstream in the cylinder, a lead groove 317 extending in an axial direction of the shaft 7 is formed in an outer circumferential surface 316 opposing with a predetermined gap to an inner circumferential surface 1a of the cylinder. The lead groove 317 serves to disturb the flow of the material to be treated passing between the outer circumferential surface 316 and the inner wall surface 1a of the cylinder 1 to complex the flow. This stabilizes feeding resistance to suppress a variation in the pressure in the cylinder 1.
