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.

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.

Disclosed is a multi-shaft laminated spiral solid-liquid separator with a pendulum motion, the separator comprising fixed rings, movable rings and screw shafts, wherein each of the screw shafts is provided with the fixed rings and the movable rings in a staggered arrangement in a radial direction to form a cavity; there are two or more screw shafts arranged in the cavity side by side, and the fixed rings and the movable rings are in the form of an annular structure with two rings staggered and communicated or multiple rings staggered and communicated.

A juicer having improved juicing performance, including: a housing in which a motor is built in; a screw housing detachably coupled to the housing; and a driving screw exposed to one side of the housing and received in the screw housing so as to rotate by being coupled to a driving shaft rotatably driven by the motor. The driving screw includes: a driving screw main body in which an installation groove opened toward the housing is formed; one or more piezoelectric element provided in the installation groove of the driving screw main body; and a contact terminal electrically connected to the piezoelectric element and electrically contacting a contact electrode provided in the housing.

A solid/fluid separation module (300) and press comprises at least one filter unit (301) for a solid/fluid separating press having a barrel with a core opening (112) for at least one conveyor screw. The filter unit includes a pair of end plates (321,322) and a plurality of intermediate filter plates (314) placed one behind the other and sealingly compressed into a plate stack (310) between the end plates. Each intermediate plate (314) has at least one drainage perforation (362) separate from the core opening, the core opening and drainage perforation each extending from a front face to a back face of the intermediate filter plate. In the filter unit, all end plates and barrel plates are aligned such that the core openings form the core passage of the filter block and such that the drainage perforations form an internal fluid collection chamber (338) within the filter unit.

The invention relates to a screw press for separating filtrate from a feed material. It is characterised in that a sensor arrangement comprising a sensor for measuring the filtrate content is arranged in the discharge area, the feed material flowing towards and/or around the sensor. This allows simple, prompt, and accurate measurement of the filtrate content.
