<P>PROBLEM TO BE SOLVED: To suppress energy consumption when replacing a liquid component of a mixture with a supercritical fluid. <P>SOLUTION: A liquid extraction device 20 includes an accommodation part 450 and a filtering extraction part 452. The accommodation part 450 accommodates a mixture and a supercritical fluid. The mixture includes a solid component and a liquid component. The filtering extraction part 452 extracts some of the liquid component from the mixture, by filtering the mixture in the accommodation part 450. The liquid extraction device 20 further includes a pressurizing part. The pressurizing part pressurizes the filtering extraction part 452 so that a pressure is applied to the mixture when the filtering extraction part 452 filters the mixture. <P>COPYRIGHT: (C)2013,JPO&INPIT |
