摘要： A disclosed dryer includes a receptacle configured to contain material to be dried, an air duct configured to route recirculating air and/or fresh air to the receptacle, a heating device configured to heat the recirculating air, and at least one sensor. The sensor is configured to determine a relative humidity and/or temperature, and the air duct includes at least one adjusting element configured to modify a portion of recirculating air routed to the receptacle. The dryer further includes a control or regulating device configured to control or regulate the portion of recirculating air routed to the receptacle and/or a heating capacity of the heating device during a drying process. A disclosed method includes controlling a portion of recirculating air routed to the receptacle and/or a heating capacity of the heating device. Further, a mixture of recirculating air and fresh air are varied during heat-up, drying, and cool-down phases.

摘要： With respect to an especially efficient use of energy required for drying, a drier for drying items to be dried, comprising a receptacle for the items to be dried, an air guide for guiding air to the receptacle and a heating device for heating the air is designed and further developed in such a way that the receptacle comprises a plurality of modules (1, 2, 3, 4), arranged one behind the other, for heating, drying or cooling the items to be dried, and that at least one module (1, 2, 3, 4) is associated with a conveying device (5) for conveying the items to be dried from this module (1, 2, 3) or any module (1, 2, 3) to the next module (2, 3, 4).
