The apparatus for the extraction of ingredients from plant material, in particular alkaloids or tobacco flavors from tobacco material comprises a first screw conveyor (1, 22) with at least one rotatably driven first screw (8, 25, 26), which is adapted to convey the plant material from a first screw conveyor inlet (3, 37) to a first screw conveyor outlet (4). The apparatus further comprises a second screw conveyor (9, 23) with at least one rotatably driven second screw (9, 27, 28), which is adapted to convey the plant material from a second screw conveyor inlet (6) to a second screw conveyor outlet (7). A fluid connection (5, 38) is provided in between the first screw conveyor outlet (4) and the second screw conveyor inlet (6). The fluid connection is adapted to enable flow of plant material from the first screw conveyor outlet to the second screw conveyor inlet. The first screw conveyor has a first fluid outlet at its downstream side. The second screw conveyor has a second fluid outlet at its downstream side.

An auger system and method that comprises at least one auger. The auger(s) are situated in a processing chamber that is adapted to receive material to be processed by the auger(s). A hopper or chute is associated with the processing chamber in order to direct material into the processing chamber to be processed by the auger(s). The hopper or chute comprises at least one door that is adapted to move into a position to assist with suppression and/or containment of smoke and/or fire that may emanate at any time in such material (e.g., before, during, or after processing of the material by the auger(s)).

The present invention relates to a dosing device for a product in powder form, comprising a holder (10) intended to hold a first quantity of the product therein. The holder is provided with dosing means to draw off the product from the holder and move it to an outlet. The dosing means comprise a worm body (20) with a worm thread (21). In a first aspect the worm body comprises at an outer end facing toward the outflow opening at least one further worm thread (22) which runs between the first worm thread (21). In a second aspect the worm thread (21) encloses a smaller volume between successive turns at a base than between successive turns in a part thereof located further toward the outer end.

Repaired combine augers are provided that can include: a central cylindrical object configured to support flighting extending about the central cylindrical object, wherein at least one portion of the flighting is damaged and defines non-linear portions, openings, and/or bent sections; and at least one semi-circular repair component bound to the portion to align with remainder of the flighting.

A system and method for feeding a high volume of low-bulk-density and pressure-sensitive feedstocks into a pressurized environment. The system includes a lock hopper filling system, one or more lock hoppers, a feed bin, and a feeder. The methods involve using such a system to feed bulk materials into a pressurized environment by feeding bulk material from a low pressure into the surge bin, filling the one or more lock hoppers from the surge bin, operating the lock hoppers, and discharging lock hoppers into feed bin, and discharging feed bin into the high-pressure zone using feeder.

A zero contact double screw and ergonomic double screw housing combination for foodstuff mixers and portioning devices. The system includes a multi-prong support segment at the discharge end of the double screw and double screw housing which connects and secures the double screw to the double screw housing to support and space the double screw apart from the surrounding double screw housing in a configuration which eliminates contact between the outer surface of the double screw and the inner surface of the double screw housing. The housing has an exterior portion with scooped out portions providing for substantially reduced thickness, volume, and mass, while remaining configured to provide durability and longevity of use similar to that of a screw housing that is substantially fully cylindrical throughout its diameter.
