<p>An apparatus for use in isolating solids from liquids by evaporating the liquid, including a vessel (16) for receiving a composition of liquid and solid substances, a gas supply (41) for supplying a drying gas; a gas line (42) for directing the dryness gas from the gas supply (41) to the vessel (16); a liquid supply (58) for supplying a solvent capable of dissolving the solid substance and a liquid line (49) for directing the solvent from the liquid supply (57) to the vessel (16). Also included is a sensing means (36) for sensing conditions of evaporation within the vessel (16) and an automatic control system (62-64) adapted to sequentially initiate a flow of drying gas to the vessel (16), initiate a flow of solvent to the vessel (16) in response to sensing of a given evaporation condition by the sensing means (36), interrupt the flow of solvent to the vessel (16) after a certain quantity of solvent has been received thereby, and interrupt the flow of drying gas to the vessel (16) in response to sensing of a particular evaporation condition by the sensing means (36). The apparatus automatically produces an evaporation cycle, a solvent reconstitution cycle, and a re-evaporation cycle thereby significantly reducing previously required costly manual procedures.</p> |
