Zusammenfassung:	PURPOSE:To wash a porous material with a less amount of water in a short time, by feeding continuously a pressurized wash liquid to a porous material in a specified vessel and discharging the wash liquid while keeping it so as to immerse the porous material therein. CONSTITUTION:A porous material 6 is fixed to a partitioning plate 8, which has many pores and allows liquid to pass therethrough, by means of a press means 4. A liquid-feeding valve 3 is opened and a wash liquid is pressurized to 2-20kg/cm and continuously fed to the material. The liquid is controlled so that it exists above the top of the porous material 6. A gas and liquid discharge valve 9 is opened and, after a given time, the valve 3 is closed.
