Drying apparatus

The apparatus (2) has a drying chamber composite (4) with multiple drying chambers (A-D), and a fluid distribution unit introducing drying medium i.e. air, from one of the drying chambers. A control device i.e. personal computer, controls the fluid distribution unit. The chamber is connected with the control device for sensing flow conditions of fluid distribution in-flowing the chamber and out-flowing the chamber. A sensor arrangement comprises sensors e.g. temperature sensor, humidity sensor, air speed sensor and/or pressure difference sensor, that are spaced at each other in flow direction. An independent claim is also included for a method for operating a drying chamber composite with multiple drying chambers utilizing a drying apparatus.
