In some embodiments, the apparatus comprises an inlet for receiving the kitchen waste, a comminuter to comminute the received waste, a dewatering device to dewater the comminuted waste, a compressor to compress the dewatered comminuted waste, and an outlet to provide processed waste ready for collection, wherein the inlet has a lid moveable between a closed position and an open position and the inlet communicates with a hopper having an outlet, the hopper outlet communicating with the comminuter by a door mechanism, and wherein the door mechanism and the lid are interlocked such that the door mechanism opens to supply food waste to the comminuter only when the lid is in the closed position and such that the lid is openable to allow a user to add food waste into the hopper only when the door mechanism is closed.

A system 400 for obtaining a substance from a commodity has a first apparatus 420 with first 422 and second 424 openings, a device 426 for moving the commodity through the first apparatus, and at least one blade 428 for shearing the commodity. The at least one blade 428 is positioned between the first opening 422 and the second opening 424. A second apparatus 440 has a first opening 442 and a second opening 444, with the first opening 442 being fluidly connected to the second opening 424 of the first apparatus 420. The second apparatus 440 includes a device 446 for moving the sheared commodity from the second apparatus first opening 442 to the second opening 444. A third apparatus 460 obtains the substance from the sheared commodity, including a separator 460 having a first opening 462 fluidly connected to the second opening 444 of the second apparatus 440.

A method for removing liquid from a slurry includes: (i) feeding the slurry into the inlet of a press; (ii) removing liquid from the slurry as the slurry advances through a deliquifying section of the press, thereby producing a pressate stream; (iii) forming a plug of material as the slurry is advanced through a plug formation section of the press; (iv) advancing the plug of material to a discharge section of the press; and (v) removing additional liquid from the plug of material by operating the press so that the pressure in the discharge section of the press is greater than the pressure of the pressate stream by at least 2 psi. The present invention also relates to a method for controlling discharge consistency from a press, without provision of discharge restrictors, by varying the pressure differential between a discharge section of the press and a pressate stream.

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 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 knifed 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.

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.

A method for treating a food product of vegetable origin, including the steps of pushing, by means of a pushing device, the food product within a treatment cavity. This is defined between an internal surface of a fixed hollow body, or stator, and an external surface having conical shape of a rotor, and has an inlet mouth through which the food product of vegetable origin is introduced within the same and an outlet mouth through which the treated vegetable food product exits the cavity. The treatment cavity has a size which decreases going from the inlet mouth to the outlet mouth. It is provided a rotation of the rotor within the stator about a rotation axis. The combination of the rotation and of the pushing that are carried out by the machines produce a partial crushing of the food product of vegetable origin within the treatment cavity.

A feeding arrangement comprising a transportation means (3) for transportation of material from a material supply to at least a first chute (7) and a second chute (8), a plug screw feeder (11) for feeding the material to the treatment stage. The plug screw feeder (11) is provided with a first inlet opening (12) connected to the first chute (7), which first chute (7) is provided between the transportation means (3) and the plug screw feeder (11). Further, the transportation means (3) comprises at least selectively openable first and second outlets (4, 5) arranged at different axial positions along the transportation means (2), which first outlet (4) is in connection with the first chute (7) and the second outlet (5) is in connection with the second chute (8).
