Abstract
A vortex evaporator having a holder for holding at least one container presents a chamber wherein liquid is evaporated from a liquid and solid solution in a container. The vortex evaporator also includes a drive mechanism, coupled to the holder, for moving each container in an orbital motion within the chamber to cause the solution in the container to form a vortex configuration. The vortex evaporator further includes a gas supply system for directing gas into the container to increase the evaporation rate of the liquid and a control system for controlling operation of the vortex evaporator. In an alternative embodiment, a vacuum supply system may be utilized instead of the gas supply system. Further, the vortex evaporator will preferably include a heater, at least one liquid level sensor, a heat sensor and a motion dampening assembly all located within the chamber.
