Abstract
A process for the continuous drying of granular material, preferably of cuts of organic polymers of a high degree of polymerization, characterized in that the material to be dried, continuously fed to a well drier, is swept in this, in two zones. separated, by a drying gas being connected and circulating a greater partial current constantly in the upper zone, whereby in a step heater it is kept at the drying temperature and, when flowing in the upper zone, preferably heated and conditions the material to be dried that is in it, while a minor partial current, removed together with the largest and derived from it, is constantly cooled and regenerated, to be then led back to the lower end of the lower zone, sweeping and drying the material to dry heated in the upper zone and absorbing moisture, and mixing below the upper zone with the greater partial current, with the It travels through said upper zone and then also makes partial drying possible.
