ABSTRACT:
A fluidized-bed dryer includes a vertical fluidized-bed drying chamber divided into at least two sections by at least one vertical partition. Each of the drying chamber sections has an inlet through which wet material is to be introduced into the respective drying chamber section, an outlet through which dry product is to be discharged from the respective drying chamber section, and a horizontal porous supporting shelf for preventing the wet material in the respective drying chamber section from falling during drying. Each drying chamber section is joined with a heated-air chamber through which heated air is introduced into the respective chamber section through the supporting shelf. The individual drying chamber sections operate batchwise repeatedly in staggering manner and independently of each other.
