Fluidised-Bed Paddy Drying

The research and development of fluidised-bed paddy drying in Thailand is described in this paper, starting with an experimental batch dryer and culminating with a commercial continuous-flow dryer. A mathematical model of the fluidised-bed paddy drying system is derived. Fluidised-bed paddy dryer is now fully commercialized in several countries. The potential is great, especially for high moisture grain. Energy consumption is relatively low while paddy quality is maintained. In addition, a significant spin-off is that head rice yield can be increased under proper drying conditions.
