Abstract (en)

[origin: EP0844081A1] The method involves generating (22) a powder gas flow from powder particles and a gas. The powder gas flow is directed towards the surfaces of the products (8) as they are moved along a conveyor surface. A transport gas flow is directed against the surfaces of the products with a speed component tangential to the conveyor surface so that the transport gas flow spatially overlaps the powder gas flow.
