DRYING CHARACTERISTICS OF POROUS MATERIALS IN A SUPERHEATED STEAM FLUIDIZED BED OF HYGROSCOPIC POROUS PARTICLES UNDER REDUCED PRESSURE

摘要

The hygroscopic porous particle was used as the fluidizing particle for the superheated steam fluidized bed drying under reduced pressure. A relatively largematerial was immersed in the fluidized bed as the drying sample. The dryingcharacteristics of the sample were examined experimentally and the results werecompared with those in the case of inert particle fluidized bed.
