Title:
RESIN PROCESSING DEVICE, RESIN PELLET PRODUCTION METHOD, AND RESIN MATERIAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/248570
Kind Code:
A1
Abstract:
A resin processing device 1 comprises: an extruder 11 to which a resin material 51 is fed; and an extruder 21 which is connected to the extruder 11 and to which residual resin discharged from the extruder 11 is fed. The temperature of a cylinder 12 for the extruder 1 is set such that the temperature on the downstream side relative to a kneading section 61 is higher than the pyrolytic temperature of the resin material 51. The temperature of a cylinder 22 for the extruder 12 is set such that the temperature on the downstream side relative to a position where the residual resin is fed is higher than the pyrolytic temperature of the residual resin.
