A commercial-scale oil-bearing material expeller press having an oil-bearing material inlet, an oil-bearing material press cake outlet and an oil outlet in a temperature-controlled barrel; said barrel housing a compression screw; said compression screw having a central shaft and a plurality of continuous or discontinuous screw flights wherein there are one or more compression zones along the direction of travel of said oil-bearing materials from said oil-bearing material inlet to said oil-bearing material outlet, wherein said central shaft increases in diameter in said direction of travel; and wherein at least said barrel is adapted to be cooled in a plurality of cooling zones.

A substantially dry product is produced by a process comprising the steps of: removing moisture from a raw material having a first moisture content to produce the substantially dry final product having a final moisture content; (b) advancing the raw material longitudinally along and between at least a first screw and a second screw comprising at least a compression zone and a dehydrating zone which are arranged successively within the first and second screws; and (c) entrapping and removing a predetermined percentage of moisture as the raw material moves through the compression zone and dehydrating zone.

Embodiments of the invention concern a supercharger (1) for feeding honey and beeswax mixture into a honey and beeswax separation screw, which comprises at least a filter pipe (3), a pipe connection fitting (4), an inlet pipe (7) for honey and beeswax mixture and an inlet pipe connection (6) for the honey and beeswax mixture inlet pipe. In an embodied supercharger, the pipe connection fitting (4) is connected radially to the side of the filter pipe (3) and to the other end of the pipe connection fitting is connected the inlet pipe (7) for honey and beeswax mixture using the inlet pipe connection (6) for the honey and beeswax mixture inlet pipe.

A juicer includes a housing being open to top and including an annular first flange on a top and at least one lower juice spout on a peripheral surface, and a support on a bottom; a filtering mechanism in the housing and including longitudinal ridges on an inner surface, screens each disposed between two adjacent ones of the ridges, annular second flanges on an outer surface, a first rim extending downward from the lowest second flange, and at least one port through the first rim; a rotating mechanism in the filtering mechanism and including an annular element on a bottom edge, a helical screw blade on an outer surface, and an electric motor for rotating the screw blade; and a feed chute on the housing and including an annular member on a bottom edge and a second rim extending downward from the annular member.

In general, the roller press provides plant products into a canal of a ribbon stream, encapsulates the plant products via the ribbon, and presses rosin from the encapsulated products so that waste products and the ribbon are discarded while the rosin is collected from of the surfaces of the press.

A low speed seed oil expeller press with the capability of extracting oil through a new design that does not crush or grind the seed so as to eliminate the need for filtration and maintain the seed oil at a temperature below 130 degrees F. The seed oil expeller press has a seed preheating capability and controls the pressure and extraction oil temperature by manipulation of the expeller speed, the head volume and the size of the pressed seed exit orifice. The seed oil expeller press eliminates seed rotation within the head volume so as to eliminate crushing, grinding or tearing of the seed by a symmetrical knived press head. The seed oil expeller press regulates seed temperature, seed feed rate, seed pressure, seed rotation and extracted seed oil temperature so as to compensate for the seed size, seed hardness and seed oil content, so as to allow for seed compression without crushing or tearing to accomplish seed oil extraction at a low (cold press) temperature.

A separator system (1) and method for separating a mixture including said one or more liquids or semi-liquids and a loose, solid material substantially into liquid and solid phases. The system includes the components of: a compression separator (100) for separating the liquid from the solid material by compression; a vacuum supply (200) for generating suction to draw mixture into the separator via a feed line. The liquids are captured in a collection tank (301) and the solids in a hopper (320).

A dewatering screw press has a hopper, a discharge outlet, a cylindrical screen flexibly mounted to the hopper and rigidly connected to the discharge outlet, a screw mounted to rotate beginning in the hopper and ending at the discharge outlet, the screw having an outer surface contacting the cylindrical screen, and at least one vibrator mounted to the cylindrical screen. Dewatering efficiency is improved by vibrations that are strong near the middle of the screen, while reducing or eliminating vibration near the discharge end of the screen where pressure is highest and a breaking of the seal between the screw and the screen due to vibration can reduce dewatering of sludge near the discharge end of the screen.

An elongated scraper profile is provided, preferably for a dewatering device that serves the purpose of dewatering sludge. The scraper profile features a lip section extending in the direction of the longitudinal extension of the scraper profile, which serves the purpose of scraping sludge components from a screen surface. The scraper profile features a fastening section extending in the direction of the longitudinal extension, which serves the purpose of fixing the scraper profile with the assistance of a retainer assembly. The scraper profile also features an intermediate section connecting the lip section and the fastening section, whereas the intermediate section is flexibly formed in a direction running perpendicular to the longitudinal extension, such that the lip section is moveable in the direction of the fastening section.

A device according to various embodiments for preparing wet grain can include at least a first screw configured to receive wet grain. A second screw receives the wet grain from the first screw. At least one of a compressing element and a dehydrating element is included with at least one of the first screw and the second screw to cause a physical property change to the wet grain.
