    摘要： The invention relates to a multi-shaft extruder for the continuous treatment and/or processing of bulk material, especially a powdery, granular or flocculent product, comprising a plurality of shafts (3) which are arranged in a crown-like manner in a cavity (1) of an extruder housing (2), said shafts extending parallel to the axial direction (A) of the extruder and forming an inner processing chamber (1a) inside the crown, and an outer processing chamber (1b) outside the crown. Each shaft carries a number of axially successive processing elements (4), at least part of the same being elements (4a; 4c; 4e) having a transporting effect, and with which adjacent shafts engage in a sealed manner at least in partial regions. At least one transporting endless screw element (4b; 4d; 4f) comprising at least one transporting screw thread (9, 10; 14, 15, 16; 19, 20) is placed in the region of the supply opening (21) in the extruder housing (2), and does not engage in a sealing manner in at least one partial region along the axial direction (A).

    摘要： The invention relates to a multiple-screw extruder that comprises a first process chamber (1) and a second process chamber (2). In the degassing zones of said extruder, at least the first process chamber is provided with at least one degassing opening. The radius R of the conveyor element in the degassing zones, in at least one conveyor element (7; 9) of at least one screw (5, 7; 5, 9) configured as a passage screw, in a subsection configured as a passage subsection (71a, 71e; 91a, 91e), along the peripheral direction of the at least one conveyor element (7; 9) is by ΔR smaller than the full radius Rv of the conveyor element (6; 8) required for the mutual stripping of adhering product in a closely intermeshing screw operation with die adjacent conveyor elements (6; 8) of adjacent conventional screws (5, 6; 5, 8). The invention also relates to a method for degassing viscous or elasticoviscous flowable masses in such a multi-screw extruder having several process chambers, the respective process chambers communicating by means of a connecting opening.
