ABSTRACT:
An apparatus (10) for continuously extracting a solute from a carrier medium (102) is provided. The apparatus is formed from a vessel (12) including a convergent baffle (22) separating the vessel into a lower distillation chamber (24) and an upper extraction chamber (26). The convergent baffle is configured as an inverted funnel such that it defines a conduit riser (28) projecting upwardly into the extraction chamber and terminating in a vaporized solvent port (30) placing the distillation chamber in fluid-flow direct communication with the extraction chamber. A vapor rotating spheres-condenser (34) is mounted on the upper end of the vessel and opens into the extraction chamber. Solvent is placed in the distillation chamber while the carrier medium containing the solute is placed in the extraction chamber. Solvent is vaporized in the distillation chamber, rises upwardly through the conduit riser, and passes through the carrier medium, thereby extracting solute in a continuous linear-toroidal motion. The vapor then is condensed either into the extraction chamber or by the condenser and falls back downwardly into the carrier medium flowing through the carrier medium while extracting solute. The condensed solvent then returns to the distillation chamber via valves (35) for continuity of solvent supply. The continuous flow of vaporized solvent from the conduit riser induces a linear-toroidal flow about the conduit riser in the carrier medium that enhances the speed and efficiency of extraction.
