An adjustment assembly for adjusting a gap between a restrictor ring and an auger in an industrial food separator is provided. The adjustment assembly includes an electric motor and a mechanical assembly coupling the electric motor to the restrictor ring. The adjustment assembly is configured to translate rotation of a shaft of the electric motor into movement of the restrictor ring to change a width of the gap. A controller coupled to the electric motor. The controller having one or more processing devices, a memory coupled to the one or more processing devices, and storage media. The storage media has instructions stored thereon, the instructions, when executed by the one or more processing devices, cause the one or more processing devices to send commands to the electric motor to move the restrictor ring to change a width of the gap.

A waste processing system and method for improving compaction and/or separating organics and liquids from waste material. An elongated extrusion screw and/or an adjustable compression gate may be provided to improve the compression of waste material. An improved extraction tube may also be provided to facilitate separation and removal of organics and other liquids from the compressed material. At least one sensor may be provided for sensing an increasing accumulation of waste material awaiting to be processed. An exemplary embodiment may also be adapted to add dry fraction to a waste load that is wet with organics or other liquids to improve compressibility. A system and method may also be adapted to automatically adjust to improve compression of the material and facilitate more efficient production.

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 low speed seed oil expeller press with the capability of extracting oil through a new seed compression design that eliminates the need for filtration, and maintains the captured seed oil at a temperature below 130 degrees F. It has a seed preheating capability and controls the pressure and extraction oil temperature by adjustments of the expeller speed, the head volume and the size of the pressed seed exit orifice in the thorn. 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.
