FIELD: processing of various raw materials, in particular, extraction equipment. ^ SUBSTANCE: apparatus has pump and high-pressure cylinder, extractor, separator, accumulating reservoir for solvent, connection pipes, measurement and locking-adjustment fittings, system for cleaning of solvents from admixtures, solvent regeneration system, group consisting of three sequentially arranged separators designed for fractioning of base product, automatic system for measuring and controlling of thermodynamic parameters of solvent within extractor and separators, and at least one additional high-pressure cylinder positioned in parallel with main high-pressure cylinder so as to provide for alternating functioning thereof in order to receive solvent from high-pressure pump and feed it into extractor. Automatic system for measurement and controlling thermodynamic parameters of solvent and units of said apparatus are designed so as to carry out extraction processes therein at temperature of 20-600 C under pressure of 0-60 MPa, followed by fractionation separation of base product at temperature of from -5 C to +20 C under pressure of 0.1-0.5 MPa. ^ EFFECT: increased process velocity, enhanced extraction extent and purity of base product, maximum efficiency of extraction process due to reduced solvent losses. ^ 1 dwg |
