[Problem] A separation device and a separation method that have a high separation efficiency are provided. [Solution] A separation device 1 includes a shredding unit 10 (first shredding unit), a separation unit 20 (first separation unit), a shredding unit 30 (second shredding unit), and a separation unit 40 (second separation unit). The shredding unit 10 shreds a disposable diaper (processing target) containing a plastic (first material) and a water-absorbent polymer (second materials) adhering to the plastic into fragments. The separation unit 20 rotates a drum 22 in a state in which the disposable diaper fragments shredded by the shredding unit 10 are accommodated therein, thereby separating the water-absorbent polymer passing through holes 22a from the disposable diaper fragments. The shredding unit 30 shreds the disposable diaper fragments from which the water-absorbent polymer passing through the holes 22a is separated by the separation unit 20. The separation unit 40 rotates a drum 42 in a state in which the disposable diaper fragments shredded by the shredding unit 30 are accommodated therein, thereby separating the water-absorbent polymer passing through holes 42a from the disposable diaper fragments. |
