This research aims to develop the design of vertical bed dryer which could dry corn kernel. The dryer characteristics has been investigated. The dryer design consists of three chambers which each in order to facilitate of inlet hot air dryer stream, corn kernel chamber, and outlet wet air. Each chamber was separated by perforated plate steel. Air flew by a blower and heated by 2 x 350 heaters. The research parameter was: (a) drying air temperature, varied 50-60 oC, (b) air velocity varied of 2-4 m/s, blower power (W), and moisture content, mc (%). The resuts shows that moisture content decreasing of 5 kg corn kernel from 20% to 10% took 24-26 minutes.
