Abstract: The invention starts out from a fluidizing apparatus (1) for conditioning solid particles, consisting of a distribution chamber (2), a turbulence chamber (3), wherein the turbulence chamber (3) has separating walls (10) or the like for conveying solid particles along a conveyor path, a solid particle inlet unit (6) as well as a solid particle outlet unit (7) and a flow receiving base (11), wherein an air distribution plate (18) is arranged below the flow receiving base (11), and opening ratios, which result through openings (22) in the air distribution plate (18), vary.
