<p>The process for the drying drainage of water-containing masses causes the energy-saving drying by means of air which is guided in a closed circuit successively through a secondary dryer (14), a pre-dryer (12), a dehumidifier with heating (54, 56) and again to the secondary dryer. The energy expended in the dehumidifer (54) is conveyed back to the air in the form of heat. Excess energy, which is produced during operation of the dehumidifier, is used for heating the material to be dried. <IMAGE></p> |
