FIELD: machine building.SUBSTANCE: for extraction (leaching) of the substances extracted from the plant materials in food, chemical-pharmaceutical and other industries, for output increasing of the substances extracted from the extractable plant materials and for increasing of their concentration in the ready extraction it is suggested to provide the extractor with the extractant recirculation circuit containing devices for solid phase separation, pump, discharge tank, flowmeter, shutdown valves system, and in the extractor bottom part additionally union will be installed for continuous liquid phase supply.EFFECT: wider possibility of return in the vessel of part of extraction after solid phase separation in specified ratio with fresh extractant, thus improving conditions of mass exchange due to decreasing of the surface tension of the liquid phase.1 dwg |
