摘要： An extrusion pelletizer for a polycarbonate resin includes: an extruder; a cooling unit; and a cutter. The extruder includes a cylinder top, a first adapter, a polymer filter unit, a second adapter, and a die head. The polymer filter unit includes a plurality of stick-shaped filter elements therein. A temperature of the second adapter is set to be lower than a temperature of the polymer filter unit. The cooling unit and the cutter are disposed under an atmosphere in which air cleanliness defined in accordance with JIS B 9920 is any one of class 1 to class 7.
