<p>The invention relates to an oil and fat industry, in particular, to production of vegetable oils by a method of extraction by organic solvents. Aim of the invention is to provide such method of the vegetable oils extraction, such device for its implementation, and such extractor of a submersible type being a part of the device, which allow to increase intensity of mass exchange at the extraction stage, to increase concentration and purity of produced miscella, providing heightening output of the extracted oil and improving its quality, and also to obtain defatted meal suitable for further processing. For achieving these aims, the process is carried out at a temperature of phase transformation "fluid-vapor" in conditions of cavitation and intensive mixing of the solvent in non-mixed surrounding of a solid phase of the material under extraction, and solvent vapors, which are produced in this process, are removed, condensed and returned back into the process, providing the re-circulation of the solvent.</p> |
