METHOD FOR RECOVERING CRYSTAL FROM SLURRY

摘要

PURPOSE: To provide a method for continuously recovering crystals over a long period from a slurry with a rotary vacuum filter without causing the clogging of the filter medium. CONSTITUTION: A slurry composed of crystals and a solvent is supplied to a rotary vacuum filter and a cylindrical filter medium is rotated to continuously perform the suction filtration, the washing, the suction filtration and the peeling of the cake.
