摘要

A device for introducing a gaseous flow stream in an apparatus for granulating and coating particles in a spouted bed including a flow directing structure located between the spouted bed containing portion of the device and the gaseous flowstream feeding portion. The flow directing structure directs the gaseous flow stream in the upward direction for preventing contact and agglomeration of particles in the vicinity of walls of the device.
