ABSTRACT:
A reactor for drying solids in a heated fluidized bed comprising over the fluidized bed a vapor-collecting space provided with a vapor outlet. Means for feeding the water-containing solids are provided over the vapor-collecting space. A conical distributor surface, which is rotatable about a vertical axis, is provided in the vapor-collecting space below the supplying means and slopes at an angle of 25.degree. to 70.degree. from the horizontal and is formed with at least one aperture. The aperture occupies 10 to 90% of the theoretical overall area of the distributor surface. The distributor surface is rotated at a speed of 20 to 250 revolutions per minute.
