FIELD: process engineering.
SUBSTANCE: invention relates to filtration. Method of crystalline suspension filtration for extraction of crystals by continuous vacuum filtration comprises filtration, flushing and lifting-on of suspension bearing crystals and solvent to be carried out multiple times. It differs from known procedures in that crystals are flushed by flushing fluid overheated to, at least, vapor point.
EFFECT: rued out clogging.
