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.

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.

A juicer cartridge includes a liquid impermeable compartment at least partially surrounding food matter. An information region may be disposed on the liquid impermeable compartment, wherein the information region includes information for controlling at least one pressing parameter for pressing the juicer cartridge, such as a desired pressing speed, force profile, pressing temperature, total pressing stroke, number of pauses, number of press and/or retract cycles, and a distance of a press and/or retract cycle. The juicer cartridge may be used by placing it in the pressing chamber of a juicer that reads information from the information region and presses the juicer cartridge using the information.

A screw press includes a filter casing having inlet and outlet sections and a filter section therebetween. A screw is mounted in the casing for conveying a solid-liquid mixture from the inlet section to the outlet section while compressing the solid-liquid mixture and forcing at least part of a liquid content thereof to be expelled out of the filter casing. The casing and the screw are of modular construction. The filter section has at least first and second serially interconnectable filter sections, and the screw has at least first and second serially interconnectable screw sections respectively disposed in the first and second filter sections for joint rotation as a unitary component. The first and second screw sections have a continuous screw flight having a flight outside diameter. The first and second screw sections are detachably coupled to one another by a coupling provided at the outside diameter of the flight.

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.

Apparatus for pressing and drying a pre-defined amount of waste includes a metal main frame positioned to provide rigid support, and a body mechanically linked to the main frame through a plurality of linkage plates. The apparatus also includes an inlet vertically mounted on the body and a twin screw assembly to press and dehydrate the pre-defined amount of waste. A plurality of mesh screens is rigidly linked to the main frame along the longitudinal axis of the apparatus to remove compressed liquid. The body is also designed to support rotation of the twin screw assembly, and the inlet includes an ingress cross-sectional opening to receive the pre-defined amount of waste.

A reusable, flexible outer support bag for supporting a disposable filter bag removably placed inside the outer support bag during a juice pressing operation which applies pressure against the outer support bag and inner filter bag, the outer support bag having one or more juice outlets whereby juice pressed from a foodstuff located inside said disposable filter bag passes through the filter bag and is directed out of said outer support bag through the juice outlets, the outer support bag providing support to the filter bag and preventing rupture thereof during the application of pressure.
