ECONOMICS OF STIRRING DEVICES IN GRAIN DRYING.

Stirring devices are frequently used with in-bin drying of grain. The addition of a stirring device to three in-bin drying methods was analyzed with regard to economics. It was concluded that adding stirrers to a functioning in-bin drying system (a) was generally economical for layer drying; (b) was not generally economical for natural air drying; (c) was economical for low-temperature drying only with larger bin diameters and relatively higher corn prices.
