Abstract (en)
[origin: EP0359285A2] The apparatus for briquetting plant material, especially stalks, comprises a conical worm compactor (27) of which the worm (29) driveable in rotation possesses, at least at its end at the front in the conveying direction, a conically tapering outer contour defined by a plurality of turns of at least one worm helix (51) projecting from a conical worm core (49) and projects a cone-shaped compactor (33) of a worm housing (35). Ribs (53) project from the inner cone surface (55) of the conical space (33) towards the worm (29) and surround the worm (29) in the form of a conical helix with a turn direction opposite the turn direction of the worm (29). The rib (53) in the form of a conical helix appropriately extends as far as an outlet orifice (41) and screws the compacted stalks, co-rotating with the worm (29) at least to a limited extent, towards the outlet orifice (41). The apparatus possesses a press die (45), the outlet cross-section of which can be varied via a wedge mechanism (73, 79, 81). Inserted between the press die (45) and the conical worm compactor (27) is an annular part (43) which on its inner circumference (57) has a plurality of capillary degassing slots (63) open to the environment. <IMAGE>
