This paper concerns with experimental study of deep-bed grain drying in a 0.75 meter diameter dryer- column. The experimental work were carried out in the range of drying conditions such as drying air flow rate (0.08 - 0.12 m/s), drying air temperature (50 - 70 oC), and thickness of bed layer (2.5 - 5 cm). The experimental data presents the dynamic of moisture content of corn grain corresponding with drying condition. The dynamic of moisture content has been analyzed for the variable condition to carry out drying of corn grain. The drying-rate curve was shown at the various drying-air temperatures. Furthermore, the experimental data will be used to validate the developed model. For the dry grain load of 12 kg, we need about 2.25, 2.8 and 4.2 hours of drying time for drying air temperature 70, 60, and 50 oC respectively. The experimental results show that this dryer can be used
