FIELD: drying processes with use of heavy packing. SUBSTANCE: method includes forming transfer layer of packing moving over closed trajectory inside closed spiral passage, blowing this layer with drying agent, feeding moist material to transfer layer of heated packing, distributing it over surface of layer, performing conductive-convective drying of material and discharging dry material from drying zone by means of drying agent pumped through passage at rate exceeding terminal velocity of dry material. EFFECT: enhanced efficiency. 4 cl, 3 dwg
