  • Apparatus and process for drying a moist material dispersed or dispersible in a stream of drying gas
    Patent number: 5647142
    Abstract: In an apparatus for drying a moist material in a stream of drying gas the residence time is increased by inserting one or more perforated plates, above which fluidized particle layers are created, and through which a portion of the drying gas and material to be dried are passed, whereas the remaining part of the drying gas and material is by-passed said perforated plates. Improved drying capacity, heat economy and operational flexibility and decreased risk for heat damage of the material to be dried are obtained.
