A food processor includes a tubular member, and a spindle inserted into the tubular member and including a guide entry section, a crushing section, a grinding section, an extension section, a guide exit section, a guide thread helically wound around the guide entry section, a crushing thread helically wound around the crushing section, and a plurality of spaced-apart grinding threads helically extending from the grinding section to the guide exit section. The guide thread has first and second ring segments each helically extending one revolution around the guide entry section. The first ring segment has a thread depth smaller than that of the second ring segment.

A device according to various embodiments for preparing wet grain can include at least a first screw configured to receive wet grain. A second screw receives the wet grain from the first screw. At least one of a compressing element and a dehydrating element is included with at least one of the first screw and the second screw to cause a physical property change to the wet grain.

A composting garbage disposal for under sink use in a kitchen which separates food waste items into liquid and solid components. The liquid components are directed to a standard sewer or septic system. The solid components are directed to a removable storage bin. The food waste items are separated by use of a motor driven auger member which is in close proximity to the inside wall of a screened cup so that the liquid exits the screened portion of the cup and the solid exits through an aperture in the floor of the cup. A microprocessor circuit senses the strain on the drive motor and if the strain becomes excessive, automatically reverses the direction of the shaft and auger thereby releasing excess food waste that is causing the excess strain.

The invention relates to a screw press (1) for dewatering sludge, whereas the screw press (1) features at least one inlet opening (2) for the sludge to be dewatered, whereas the screw press (1) features a pressing assembly, with the assistance of which the sludge is able to undergo a pressing process after passing the inlet opening (2), with which the liquid (9) present in the sludge is at least partially driven out of the sludge, whereas a pressing assembly comprises a worm shaft (4) that is movable in a rotational movement with the assistance of a drive (17) and several screen elements (5) surrounding the worm shaft (4), at least in sections, during the operation of the screw press (1), whereas the screen elements (5) feature a screen surface (6) turned towards the worm shaft (4) and a support structure (7) securing the stability of the screen elements (5), whereas the pressing assembly features at least one outlet opening (8) for the liquid (9) driven out of the sludge with the assistance of the worm shaft (4), and whereas the screw press (1) features at least one discharge opening (10) for the sludge (11) that is at least partially dewatered with the assistance of the pressing assembly. In accordance with the invention, it is proposed that the screw press (1) features at least one holding unit (12), with the assistance of which at least the support structure (7) of at least one screen element (5) can be fixed in a maintenance position, in which the screen surface (6) of the corresponding screen element (5) is spaced apart from the worm shaft (4).

Disclosed is a solid/liquid separation apparatus including an extruder press combined with a solid/fluid separation module for separating fluid from a mass of solids compressed by the extruder at elevated pressures. The extruder includes two or more extruder screws with flighting intercalated at least along a part of the extruder barrel. The separation module forms a continuation of the barrel, receives the pressurized mass and at least a portion of the twin screws, and includes a filter pack consisting of a filter plate and a backer plate. The filter plate has a throughgoing filter slot extending away from a core opening and into the filter plate for directing fluid away from the core opening. The backer plate has a core opening shaped and sized equal to the barrel and defines a passage for guiding fluid collected in the filter slot to an exterior of the filter pack.

A screw press includes a press-chamber, wherein a screw shaft supporting thus the screw shaft surrounding by a screen-jacket and may rotate about a screw shaft axis, wherein the screen-jacket is fastened to a screen-jacket retaining device within the press-chamber and screen-jacket is formed by multi-part screen-cages having screen-cage inserts. Multi-part screen-cages are formed by two half-shells and, between at least one pivoting hinge arranging, on a bar, extending through press-chamber and arranging parallel to the pivot axis, as part of the screen-jacket retaining device and firmly connected to both half-shells. Half-shells and supported thus the half-shells pivoting in relation to each other, unhindered access to the screen-cage inserts enabling swung-open state. A cage tab is arranged on each half-shell on the side facing away from the pivoting hinge, which cage tab detachably fastening to the screen-jacket retaining device by the cage closing in the closed state of the half-shells.
