Fluidized bed paddy dryer is commercially successful at present. The dryer is applied to be used with corn grain, another important crop in Thailand. The objective of this research is to investigate performance of industrial-scale fluidized bed corn dryer. Parameters affecting drying rate, energy consumption and product quality were considered. Experimental results showed that the rate of water evaporation increased with initial moisture content of corn and drying air temperature while specific energy consumption increased when initial moisture content decreased. Corn quality in terms of breakage and stress crack increased when drying air temperature increased or final moisture content decreased.
