<p><P>PROBLEM TO BE SOLVED: To provide a solid material drying method and device capable of inexpensively recovering solid valuables by easily and efficiently drying solid material in a wet state after treatment while reducing heating energy. <P>SOLUTION: The solid material drying method, and device are characterized in that in a process wherein solid material is produced or left after reaction with respect to a reaction using a fluid which is liquid at normal temperature, using subcritical conditions, supercritical conditions, or both of the fluid, and using at least one of an oxidizer, acid, or alkali, when cooling the process for taking out the solid material after reaction, the pressure is reduced to the atmospheric pressure in a state of substantially controlling a temperature around the solid material at a temperature higher than the boiling temperature of the fluid under atmospheric pressure, and drying under reduced pressure of completely evaporating the fluid having seeped into the solid material is carried out. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
