FIELD: food industry.
SUBSTANCE: invention relates to the fat and oil industry. Method of solvent regeneration in oil-extraction line includes condensation in separate surface condenser of secondary solvent vapours of preliminary distillers, condensation in corresponding surface condensers of secondary solvent vapours and water of final distiller, toaster, desorber, a water evaporator and steam ejectors, and solvent vapours diverted from the extractor and the capacitive equipment, recuperating the solvent in the oil absorption line from uncondensed vapours diverted from the surface condensers, separating the solvent condensate stream and water in water separator to solvent, which is returned to extractor, and water with subsequent treatment in water evaporator, wherein the solvent condensate from the separate surface condenser for condensation of secondary solvent vapours of the distillation mixers is separately controlled for the presence of water in the continuous settler or hydrocyclone, then the solvent is heated to a temperature close to boiling point and directed into the extractor.
EFFECT: invention increases regeneration efficiency of the solvent.
