  • Screw extruder mechanism, in particular twin-screw extruder mechanism, for the processing of strongly outgassing materials
    Patent number: RE44826
    Abstract: A screw extruder mechanism for the processing of strongly outgassing materials comprises a main extruder for proper material processing, a material feed and discharge device and a degassing device on the main extruder for the discharge of the gas stream from the portion of evaporation. For the gas stream to branch into at least three separate streams, the degassing device comprises a first degassing port and at least two degassing elements which are opposed radially to each other in relation to the main extruder and are disposed between the portion of evaporation and the first degassing port and which are designed preferably as ancillary screw extruders opening radially into the main extruder.
