An apparatus and method for the spray drying of solvent-containing compositions. A liquid or paste-form solvent-containing composition is heated to a temperature above the boiling point of the solvent, transported under excess pressure and at a temperature above the boiling point of the solvent to a relaxation space where it is sprayed to evaporate the solvent. The relaxation space is not under excess pressure and is at a temperature that is above the boiling point of the solvent.
