Abstract

A rotating evaporator includes a chamber, and a rotor assembly disposed in the chamber, and including distillation elements that each contain an internal cavity, condensation surfaces that face the internal cavity, and evaporation surfaces that face away from the internal cavity, and a vapor manifold extending through the distillation elements and configured to provide a vapor to the internal cavities. The evaporator also includes wiper assemblies configured to form a liquid film on the evaporation surfaces, condensate scoops located in the respective inner cavities of the distillation elements and configured to collect a condensate from the condensation surfaces, a condensate manifold extending through the vapor manifold and configured to receive the condensate from the condensate scoops, and a drive assembly configured to rotate the rotor assembly and including a drive shaft and drive rollers disposed on the drive shaft and contacting outer circumferential contact surfaces of the distillation elements.
