Abstract

A soln. or suspension, is fed below a filter trap, in the vapour outlet from a steam jacketed cylindrical evaporation chamber, the walls of which are swept by e.g. 4 vanes on a rotor. The orientation of the vanes, which extend the whole length of the rotor, varies in 4 different zones in inlet, occupying 5-10%. Entrainment of liquid or powder is minimal, and no supplementary precipitating appts. is necessary. The invention is used e.g. to separate alkali alcoholates from alcohols, or to recover AgCl etc. from photographic developing solns. and is operated in series with subsequent rotary dryers and coolers.
