Abstract

Four lots of F1-hybrid seed corn were dried in laboratory dryers to help understand the performance of a commercial Wisconsin bin-system dryer. Two airflow direction reversal strategies were studied. Drying temperatures were 35 and 40.5°C (95 and 105°F) in two dryers and 40.5 and 46°C (105 and 115°F) in two other dryers. Germination and energy use were not affected by the differences in drying air temperature or airflow direction reversal strategy. Drying times averaged 22% less with the higher drying air temperatures. Decreased drying time due to increased drying temperatures resulted in a 28% increase in drying capacity on the average. Final moisture gradients were greater with increased drying temperatures because airflow direction reversal was not timed properly when using the higher drying air temperatures.
