Vacuum drying in a rotating double-cone vessel with indirect heating.
Material is charged into the rotating double-cone vessel. Heat passes through the jacket while the vessel tumbles and mixes the material under vacuum; evaporated moisture or solvent is withdrawn and, where provided, condensed and recovered.
