Mobile incline kinetic evaporator

摘要

An apparatus is disclosed for drying materials wet with one or more solvents, particularly hygroscopic materials and materials wet with a high boiling point (low vapor pressure) solvent that are sensitive to heat. Wet material is loaded into a chamber, which is then sealed and caused to oscillate back and forth. Vacuum is enlisted to provide rapid evaporation of solvent at a lower temperature than possible at standard atmospheric pressure. The material is oscillated until a sudden decrease in the residual pressure of the chamber, which indicates completion of the drying cycle. Because vacuum is applied to an oscillating chamber, a rotary vacuum seal is not required to accomplish drying in accordance with the practice of the instant invention.
