| titleOfInvention | Screw extruder and have this screw extruder's cyclic annular lactide preparation facilities |
| abstract | The utility model relates to a screw extruder and have this screw extruder's cyclic annular lactide preparation facilities, the draw ratio of screw extruder (1) be 25~110, from screw rod top portion place at the beginning, be 2~20 position in screw extruder (1) draw ratio and locate the interval and be equipped with at least one vacuum blow vent, cyclic annular lactide preparation facilities, including screw extruder group to reach the collecting system that connecting screw rod extruded the unit, screw extruder group form by at least one screw extruder (1) tandem compound, the collecting system including bank of condensers (2), collection tank (3), cryrogenic cold -trap (4) and vacuum decompression subassembly (5) connected, wherein, bank of condensers (2) are and connecting screw rod extrudes the vacuum blow vent in the unit. Compared with the prior art, the utility model discloses a screw extruder's shear effect is strong, does not have the coking phenomenon during reaction liquid schizolysis and takes place, and glycolide / lactide yield of formation is high, the quality is high. |
