Beschreibung
Zusammenfassung:	The invention relates to an apparatus for processing powder in a fluidized bed, with horizontal circulation and indirect thermal transfer elements, in which: the perforated inlet screen for the fluidizing agent has attached thereto a plurality of tissue (fabric) (in number and location as required for a good fluidization); the tubular transfer elements are horizontal, rectilinear or identically undulated in the space arranged in the flowing direction of the bed and over the entire length thereof (possibly divided for successive processing zones), in a plurality of horizontal rows offset from one row to an other; the uniformizing screen for the gas flow, at the upper part of the treatment space, is of a perforated sheet and is cylindrically vaulted, with its concavity downward and has holes over 30 to 40 percent of its total surface.
