Abstract

The invention relates to a screw press (1), in particular a vertical or horizontal screw-feeder press, for pressing a liquid-containing solid material, preferably chicory root pulp or sugar beet pulp, in particular sugar beet pulp, comprising:- an enclosure (3) comprising:- at least one inlet opening (5),- at least one outlet opening (7),- at least one rotatable screw conveyor (9) enclosed by the enclosure (3) for pressing the liquid-containing solid material and for advancing the liquid-containing solid material from the inlet opening (5) towards the outlet opening (7), the screw conveyor (9) comprising:- a shaft (11) with a rotation axis (R), and- a helicoid structure (13) wound circumferentially around the shaft (11) longitudinally extending at least from the at least one inlet opening (5) towards the at least one outlet opening (7);the screw conveyor (9) and the enclosure (3) defining a path (27) for the forced material advancement from the inlet opening (5) to the outlet opening (7),characterized in that the at least one screw conveyor (9) comprises- a material flow limiting plate (33) comprising a plate body (69) bounded by a forward surface (71), a rearward surface (73) and preferably a circumferential surface (75), which material flow limiting plate (33) is located at an outlet opening (7) facing end (39) of the helicoid structure (13) such that the path (27) is limited in an axial direction and wherein the material flow limiting plate (33) is fixed to the shaft of the screw press (1), wherein the rearward surface (73) is extending in an angle, preferably perpendicular to the rotation axis (R).
