Abstract
The invention relates to an apparatus for processing a powdered or particulate product forming a vibrating fluidized bed supported by a thin, perforated bed plate which is vibrated while gas is blown upwardly through the perforations of the plate. The bed plate which is made from thin sheet metal is provided with parallel corrugations extending transversely to the direction in which the fluidized product is moved along the plate. The corrugations impart a desired stiffness to the plate and in order to promote removal of residual product from the plate when supply of product to the plate has been terminated, the openings in the plate may be formed so as to direct gas flows supplied therethrough in the same general direction transverse to said corrugations towards an outlet of the apparatus.
