Featurse:  1   Uniform and stable fiuidization ensure a homogeneous drying and cool- ing of the materials.  2   Adjusable material layer thickness, hold time and amplitude.  3   Few damages to material surface, which is suitable for drying of fragilematerials. 4   High efficiency of both mechanical and thermal respects, which can save 30-60% energy in comparison with normal units.  5   Clean contact with materials, which is applicalbe for continous production.Application:     It's applicable for drying, cooling and humidification operations of powder, granulate materials in the fields including chemicals, pharmaceutical, cereals, foodstuffs and mines etc. for example, lemon acid, dregs, vinasse, seed and slag etc.
