ABSTRACT:
A dryer has a hopper for material to be dried and an inlet line for supplying dry air to the hopper. A heating device for heating the dry air to the desired drying temperature before introduction into the hopper is provided. A return line is connected to the hopper for removing moist air from the hopper which results from the dry air passing through the material in the hopper and absorbing moisture therefrom. The return line has a part that functions as a heat exchanger. The dry air before entering the hopper is guided through the heat exchanger.
