Disclosed is a screw feeder (10) comprising a pipe (3) enclosing a feed screw 4 arranged on a rotatory shaft (5) running parallel with the length direction of the pipe (3), said pipe (3) further comprising a number of dewatering holes (6). The screw feeder (10) also comprises a number of anti-rotation bars (7) provided on, and extending along, the inside of said pipe (3), said anti-rotation bars (7) protruding in a direction towards said feed screw (4), and an inlet (1) for receiving a solid-liquid mixture arranged at a first end of said pipe (3), and an outlet (2) arranged at a second end of said pipe (3) for discharging an at least partially dewatered solid from said pipe (3). The pipe (3) includes at least one longitudinal pipe section (31) having a first peripheral zone (9) provided in the vertically lower area of said longitudinal pipe section (31) and provided with dewatering holes (6) but no anti-rotation bars (7) and a second peripheral zone (90) provided in the vertically upper area of said longitudinal pipe section (3) provided with anti-rotation bars (7), the overall pipe profile of said pipe section (31) is composed of two differently shaped pipe profiles, a first pipe profile (P1) and a second pipe profile (P2), said first pipe profile (P1) defining the shape of the first peripheral zone (9) and is a profile selected from a square shaped profile, a profile having a partly circular cross-section with a squashed end or a circle segment remove or a partly elliptically shaped profile, and the second pipe profile (P2) defining the shape of the second peripheral zone (90), where the shape of said first pipe profile (P) is selected to allow the outer edges of said feed screw (4) to remove material overlying said dewatering holes (6), and where the shape of said second pipe profile (P2) is selected so as to prohibit any contact between said outer edges of said feed screw (4) and the anti-rotation bars (7). Also disclosed is a pipe for use in such a screw feeder.

A press includes a movable platen and a non-moving platen within a housing defining a pressing chamber, an opening is defined at the top of the pressing chamber for receiving a juice pack and an outlet is defined in a front wall of the chamber vertically between the top and bottom of the movable platen. The lid may include a front portion extending over the front of the pressing chamber and defining a slot that is aligned with a slot defined by the front wall to form the outlet. The front wall, the lid, and a sidewall may be removable for cleaning. The juice pack may have edges defining a rectangle with a spout at a first corner and an aperture for suspending the juice pack in the pressing chamber at a second corner that is intersected by a same edge intersecting the first corner.

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 device for dewatering feedstock that is pourable or free-flowing by compression and segments for use with such a device. A housing has a shell pipe in which a shaft with flights running around its circumference rotates around an axis of rotation. A feedstock is transported through the housing and compressed. The pressate is conveyed out of the device through holes in the shell pipe. An internal pipe is provided within the shell pip. The internal pipe has numerous segments with holes. The outer surface of the segments rests directly on the inner surface of the shell pipe. The holes in the segments overlay the holes in the shell pipe. The segments are made of wear-resistant cast or sintered material.
