Several physical parameters, including temperature and moisture content of corn seeds submitted to stationary drying process with radial air distribution, by combinating different air flows (18,6, 20,3 and 24,7m3/min./t) and temperatures (40, 44 and 48°C) were studied during different periods of time and position of the seeds in the seed mass 61,5cm depth. It was concluded that gradient moisture content of seeds on extreme positions of the seed mass in relation to the blowing cilinder, increased as temperature increased and decreased as air flow increased. Increasing of air flowing was more efficient than increasing temperature to accelerated seed drying speed. The best heat utilization for drying was obtained with air flowing of 24,7m3/min./t, however if combined with air temperature of 48°C a reduction of speed drying was observed.
