One of the keys to successful in·bin grain drying and aeration is the matching of a drying or aeration fan to the drying or storage bin. A properly designed system will be more efficient in terms of both drying and energy utilization. The quantity of air that may be delivered through the grain depends upon grain type, bin size, fan type, fan horsepower, depth of grain, percent of foreign material and the extent to which the grain is packed.
