The invention relates to a method and a drying machine (110) for drying materials, for example foundry sands, laundry, chemical pulps and/or bulk materials. The materials to be dried are loaded into a drying container (120), in which liquid is vaporized. The steam produced is passed into a condensation chamber (130) and condensed there in thermal contact with the material from the drying container (120). In this way, the heat of condensation can be recovered for a renewed vaporizing process. The drying machine may be used in particular in a regeneration plant for inorganically bound foundry sands. |
