Abstract

The present invention refers to a process for drying solid organic substances in aqueous phase including the steps of: feeding a continuous flow of such organic substances having a water content=50% by weight into a turbodrier having a cylindrical tubular body with horizontal axis, equipped with inlet and outlet openings, a heating jacket for bring the inner wall of the tubular body to a predetermined temperature, a bladed rotor extending inside the cylindrical tubular body (1) where it is made to rotate at speeds between 15 and 40 m/s, so as to disperse the continuous flow of organic substances into a flow of particles of organic substances; centrifuging the particles of organic substances against the inner wall of the turbodrier heated to a temperature above 130.degree. C., with formation of a thin, dynamic, highly turbulent tubular fluid layer, which advances substantially in contact with the inner wall of the turbodrier towards the outlet opening; continuously discharging, from the turbodrier, a flow of organic substances in disgregated wet solid form having a water content=45% by weight; continuously feeding the flow of disgregated wet solid into an drier operating at a temperature lower than or equal to 160.degree. C.; continuously discharging a flow of dry product having a water content=20% by weight from the drier.
