A heated medium circulates in this jacket. The drying chamber also has a supply opening for moist material close to the vane assembly, at or through the bottom of the drying chamber, an outlet opening for dried material and an opening for expelling moist air, in addition to which said vane assembly is rotatingly mounted in the drying chamber on a driven shaft extending along the drying chamber's cylinder axis, along the circumference of which vane assembly there are provided oblique, plate-shaped elements which raise the material from the vane assembly towards the upper area of the drying chamber, characterized in that that the vane assembly on the side towards the bottom of the drying chamber is formed with one or more scraping bodies which move the material from the underside of the vane assembly to the upper side of the vane assembly. <IMAGE>
