Abstract: A continuous process and a system for drying solid organic substances in an aqueous phase or a mixed (water/organic solvent) phase, which includes feeding a continuous stream of such substances into a continuous drier, to obtain a continuous output stream of dried powder material and steam at a temperature in excess of 100° C. for delivery to an apparatus separating the powder material from the steam. A continuous run of the powder material and a continuous run of steam are discharged from the apparatus for recirculation to the drier, with the steam pressure inside the drier and the separating apparatus kept constant at a value to ensure that substantially no oxygen is present, or that the powder material cannot be ignited. The recirculation is carried out by continuous drawing, downstream of the separating apparatus, an amount of steam corresponding to the amount of steam generated within the drier.
