ABSTRACT:
The thermal energy required for spray drying a solution of a solid product in a volatile, liquid solvent is effectively utilized by partly converting the solvent to a gaseous phase in a multiple-effect evaporator and by spray drying the resulting concentrate by means of a gaseous fluid at least partly preheated by heat exchange with solvent vapor or condensate from at least two effects in respective stages of a multiple-stage heating arrangement.
