  • Patent number: 4517751
    Abstract: A process is disclosed for drying moisture-laden feedstock of a wide variety in a continuous process stream which involves passing the feedstock to a fluid bed dryer which receives organic solvent vapors capable of forming an azeotrope with the water of the feedstock stream, passing thereafter into a residence dryer provided with the heat from superheated organic solvent vapors which are passed together with the feedstock stream into a cyclone separator, from which a dried and solvent free feedstock stream is recovered. The solvent vapors are returned to the fluid bed dryer, and means are provided for recovering the solvent from the formed azeotrope and returning the same to the system. Exemplary feedstocks and solvents are disclosed.
