  • Method of degassing a flowable mass in a ring extruder
    Patent number: 7981340
    Abstract: The method of degassing is performed in a ring extruder wherein at least one process chamber is provided with at least one degassing opening. The radius R of the conveyor element in the degassing zone is smaller by ?R than the full radius Rv of the conveyor element required for the mutual stripping of adhering product in a closely intermeshing screw operation with adjacent conveyor elements.
    Type: Grant
    Filed: December 7, 2009
    Date of Patent: July 19, 2011
    Assignee: Buhler AG
    Inventors: Achim-Phillipp Sturm, Jürgen Schweikle, Andreas Christel, Federico Innerebner

  • Degassing of flowable masses in a multiple-screw extruder
    Patent number: 7654725
    Abstract: 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 ?R 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).
