Fluidized Bed Dryer

A continuous Fluidized Bed Dryer (FBD) system is used to reduce moisture from soaked paddy in a parboiling system.

In FBD the wet paddy is conveyed over a perforated bed at the drying chamber. The system blows hot, ambient air through the holes of a perforated bed. The air blown will be passed through the wet paddy, behaving like a fluid and continue to flow until completely removing the moisture. Hence the name FBD.

The air velocity is adjusted to ensure fluidization, the wet paddy is thus completely exposed to drying. This process results in a high rate of heat transfer.

Application: Only paddy.
