Drying device and method for drying a substrate

A drying device, comprising:

• drying heads including at least one upper drying head and at least one lower drying head, wherein said at least one upper drying head is disposed above a transport plane, in which objects to be dried can be transported in a transport direction through the drying device, and said at least one lower drying head is disposed below the transport plane;
• said at least one upper drying head and said at least one lower drying head having air outlet slots formed therein with each having at least one air outlet slot of said air outlet slots, longitudinal directions of said air outlet slots extend substantially parallel to the transport plane and transversely to the transport direction, and slot planes, in which said air outlet slots run, intersect the transport plane at angles which are greater than 0° and less than 90°;
• said upper drying head and said lower drying head, forming a drying head pair, being disposed above each other;
• said upper drying head and said lower drying head of said drying head pair have stabilizing slots formed therein with each having at least one stabilizing slot of said stabilizing slots through which a medium can flow.
