Abstract
An apparatus for manufacturing a particulate resin, including: a fine nozzle opening configured to extrude a melted resin mixture including a resin; an extrusion output control mechanism for controlling an extrusion output of the melted resin mixture; a collision mechanism configured to collide the melted resin mixture extruded from the fine nozzle opening with a high-temperature gas stream having a temperature of not less than a Ttemperature of the resin, so that the melted resin mixture is granulated to provide a particulate resin; a heat retention mechanism configured to retain the particulate resin in an atmosphere having a temperature of not less than a Tg of the resin for 0.01 to 10 seconds; and a cooling mechanism configured to cool the particulate resin; and a method for manufacturing a particulate resin using the apparatus.
