Abstract

Two years of field tests and computer simulation with 20 years of Des Moines, lA, weather data were used to compare performance of stirred and unstirred natural-air corn dryers. For bins with the same size fan, stirring reduced drying time, electric-energy use, and overdrying. Stirring also allowed successful drying with reduced fan power and airflow. Adding stirrers to 5.5-m diameter bins was cost effective for drying 24% moisture corn and for 20% moisture corn when electricity prices were greater than about $0.08/kWh. Cost effectiveness of adding stirrers to natural-air dryers improved as corn and electricity prices, and initial corn moisture increased.
