Disclosed is a horizontal juice extractor (100) comprising a main body delimiting a food processing chamber (110) comprising a juice outlet (140), a food entry section (112) having a food inlet (130) and a food compression section (114) extending from the food entry section and having a food pulp outlet (150); a spindle (120) extending through the food processing chamber for transporting food from the food entry section through the food compression section, said spindle comprising a body (122) and a helical member (123) extending from said body; and a drivetrain (160) adapted to rotate the spindle, wherein the food compression section (114) is located in between the food entry section (112) and said drivetrain (160). The food entry section (112) comprises said juice outlet (140) at or near a distal end of said main body relative to the drivetrain, wherein the juice outlet (140) is vertically displaced relative to the food inlet (130).

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.

A screw press liquid separator includes an elongated housing having an inlet end and a discharge end, a screw cradle in the form of a sieve disposed within the housing and having a bulk material inlet disposed at the inlet end of the housing, at least one section of the screw cradle mechanically coupled to a vibrator motor, a screw formed on a shaft and disposed within the screw cradle, the screw extending from the inlet end of the screw cradle to a discharge end of the screw cradle, a motor rotatably coupled to the shaft, and pair of opposing discharge doors pivotally mounted to the discharge end of the housing and movable between an opened position and a closed position, the discharge doors driven to positions that maintain a substantially constant pressure on bulk material being driven by the screw towards the discharge end of the housing.

A dewatering system is described having an apparatus with an auger drive and a press container pulled away from a collection hopper in a first type of system. An integration of a press with an automated liquid solid separator using recirculation is a second type of system. An integration of a press with an automated liquid solid separator without recirculation and having drainage to a sewer is a third type of system. A conveyor system integration of press with an automated liquid solid separator with recirculation through use of a sump is a fourth type of system. A conveyor system integration of press with an automated liquid solid separator without recirculation and having drainage to a sewer is a fifth type of dewatering system disclosed herein.

A device is described for continuously pressing liquid out of a suspension, in particular a screw press, which may have a rotationally-driven rotor, which may rotate in a tubular screw housing and support a conveyor screw. The screw housing may be at least partially formed as a first filter jacket, which may at least partially interact with the conveyor screw and which may have radial passages for discharging the filtered liquid and which may supply a filter cake, made of retained solids, in the conveyance direction of the conveyor screw to a discharge. To provide advantageous filter conditions, a ring-shaped first sleeve, which coaxially encloses the rotor, for peeling off an outer filter cake layer from the filter cake may be associated with the rotor, downstream from the conveyor screw. A conveyance channel for the remaining inner filter cake layer may be provided between sleeve and rotor.

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.
