ABSTRACT:
A method of evaporating liquid from a liquid and solid solution in a container within a chamber involves moving the container in an orbital motion such that the solution forms a vortex configuration within the container and also involves directing gas into the container. The gas is directed into the container from a point source above the liquid in the container to decrease the partial pressure on the solution thereby increasing the evaporation rate of the liquid from the solution. To further increase evaporation of the liquid, heat may be applied to the container. The temperature within the chamber may be regulated by sensing the temperature within the chamber and controlling the application of heat to the container in response to the temperature sensed within the chamber. An alternative method of evaporating liquid from a liquid and solid solution in a container within a chamber also involves moving the container in an orbital motion, but further involves drawing a vacuum within the chamber rather than directing gas into the container.
