PROBLEM TO BE SOLVED: To solve the problem that the constitution of a device tends to become complicated and large-scale, because a step for freezing a thermoplastic resin is required. SOLUTION: When a granular resin 20 is produced, batches of a molten resin are sequentially loaded into a rotary molding tool 14b with a plurality of recessed parts 14b2 formed, and molded. Further, the molten resin of a granular shape is cooled and solidified by a cooling means while being desorbed from the recessed parts 14b2 following the rotating action of the rotary molding tool 14b, and finally recovered as the granular resin 20. |
