More Information
Summary:The invention relates to a nozzle bottom device and to a method for operating the latter. The nozzle bottom arrangement has a nozzle group with first nozzles and a further nozzle group with second nozzles. The two nozzle groups can be supplied independently of each other with a fluidizing medium. The respective volumetric flow can be switched on and off or can be adjusted variably. The first nozzles and the second nozzles are uniformly distributed over the entire surface of the nozzle bottom arrangement. As a result, a homogeneous fluidized bed is produced in the fluidized bed dryer irrespective of whether only one of the nozzle groups or all of the nozzles is or are operated.
