<p>A continuous process for drying solid organic substances in an aqueous phase or a mixed (water/organic solvent) phase, which process comprises the steps of feeding a continuous stream of such substances into a continuous drier (1), to obtain from the drier (1) a continuous output stream of dried powder material and steam at a temperature in excess of 100°C for delivery to an apparatus (3,5) separating the powder material from the steam, the latter being recirculated to the drier (1), with the steam pressure inside the drier (1) and the separating apparatus (3,5) kept constant and at such a value to ensure that substantially no oxygen is present, or that the powder material cannot be ignited, by continuous drawing, downstream of the separating apparatus (3,5), an amount of steam corresponding to the amount of steam generated within the drier (1).</p> |
