Abstract

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