Abstract

The invention relates to a plant and a method for processing plastic melts, said plant having a reactor (2) comprising a reactor housing (3) comprising first and second Two reactor housing parts (4, 5); the mixing element (12) is arranged in the second reactor housing part (5) and is rotatably mounted on the second reactor housing part about an axis of rotation (13) Above; the reactor together with the unloading device (19) is supported on the placement surface with at least one weighing device (21) connected in the middle.

Description

technical field [0001] The invention relates to a device and a method for processing plastic melts, in particular polycondensate melts, and for adjusting the intrinsic viscosity thereof. Background technique [0002] The applicant's document WO 2014 / 040099 describes a method and a device for increasing the intrinsic viscosity of a polycondensate melt under negative pressure. The melt passes through a perforated plate or screen with a plurality of holes into a chamber where a pressure of less than 20 mbar exists and falls freely through the chamber in the form of a filament and stays below the chamber in a collector for at least one minute. The melt is continuously moved under vacuum in the collector by mixing and discharge elements oriented in a horizontal position relative to the bottom of the collector, which are not completely covered by the melt. A free space remains above the melt, wherein the surface of the melt is repeatedly divided and renewed several times by the ...
