Abstract: A method for making a cylindrical centrifuge basket according to the present disclosure includes pre-perforating a metal sheet to form a perforated metal sheet having perforations aligned along rows extending across a width of the perforated metal sheet. Each row is skewed at a prescribed nonzero skew angle relative to a surface line on the perforated metal sheet, the surface line parallel to an axis of rotation of the cylindrical centrifuge basket. The method further includes roller forming the perforated metal sheet to produce a perforated basket wall sheet, coupling a first edge of the perforated basket wall sheet to a second edge of the perforated basket wall sheet to form a cylindrical basket wall, and coupling a first end of the cylindrical basket wall to a ring, coupling a second end of the cylindrical basket wall to a baseplate, or both to form the cylindrical centrifuge basket.

Abstract: An industrial centrifuge for extracting one or more compounds from biomass includes a centrifuge basket disposed within a cylindrical vessel. The centrifuge basket includes a cylindrical sidewall comprising an upper perforated portion and a lower solid portion and a basket baseplate coupled to the sidewall between the upper perforated portion and the lower solid portion. The centrifuge includes a spindle coupled to the basket baseplate, a spindle bearing assembly, and a contact seal disposed between the spindle bearing assembly and the basket baseplate. The lower solid portion of the sidewall, the spindle, and the basket baseplate define a skirted volume. During operation of the industrial centrifuge, air trapped within the skirted volume provides an air seal between an extraction fluid in the cylindrical vessel and the contact seal, spindle bearing assembly, or both, to prevent extraction fluid from contacting the spindle bearings and causing damage thereto.

Abstract: The present disclosure includes a centrifuge system for processing a massecuite composition. The centrifuge system may include a centrifuge having a vertical spindle, a housing, and a basket disposed within the housing. The basket may include a central hub coupled to the vertical spindle for rotation therewith, a cup coupled to the central hub or an end of the vertical spindle, and a loading cone positioned over the cup and coupled to the cup by a plurality of vanes extending outward from the cup to the loading cone. The loading cone may have a wide end open towards a bottom of the basket, and the plurality of vanes may be radially spaced apart. The centrifuge system may further include a feed pipe vertically disposed above the cup and having a feed outlet oriented towards the cup. The cup defining a cavity oriented in a direction away from the central hub.

Abstract: Disclosed are a device and method for the simultaneous fusion of multiple plastic pipe sections. A plurality of pipe sections may be rigidly held, faced off, heated, and joined at the same time using a single piece of equipment. The inventive process allows increased throughput of the fusion process without significant additional costs.

Abstract: Disclosed is a method, apparatus, and design of a fusion welded pipe wherein the effects of an inner bead of the fusion weld are minimized. The internal shape of the pipe prior to welding may be configured in several different shapes so that the beads or lips produced by the fusion welding process are unobtrusive and do not interfere with the function of the pipe. In a likewise manner, the outer shape of the pipe prior to welding may be configured so that the lips are unobtrusive on the external surface of the pipe.
