摘要： A drying device for drying bulk material has one or more storage containers for the bulk material and a heating device for heating the drying air for drying the bulk material. A drying air conduit is connected to the heating device and the storage containers and guides the drying air to the storage containers. One or more first mixing valves are arranged in the drying air conduit upstream of the storage containers, wherein the first mixing valves are used to adjust the temperature of the drying air before the drying air enters the storage containers. The heating device has also the function of regenerating the drying units provided for removing the moisture from the drying air.
