Claims12
An extruder system for degassing a mixture comprising:
- a first extruder,
- a second extruder arranged above the first extruder in relation to a gravitational direction and downstream of the first extruder, and
- a transfer zone formed between the first and second extruders;
- characterized by a pressure control device by which the pressure of the mixture at the discharge of the first extruder can be regulated;
- wherein the extruder system comprises a means for increasing a surface of the mixture passed through the transfer zone;
- wherein the transfer zone includes a first pipeline part arranged parallel to the first extruder and positioned downstream of the first extruder and a second pipeline part arranged perpendicular to the first pipeline part and positioned between the first pipeline part and the second extruder, wherein the pressure control device includes a slide valve within the first pipeline part which narrows an opening from the first pipeline part to the second pipeline part.
