Study was made of how well a prototype in-store drying system would control aflatoxin contamination and how much energy the system would consume. Tests were done using air with a defined relative humidity and temperature. To maintain high quality maize by limiting aflatoxin productin, high moisture maize shoud be dried to 18 or 19 percent moisture content (wet basis) within 2 days and continuously dried to 14 percent within 14 days. To decrease moisture content from 19 to 12-13 percent using an air flow rate of 3.6-4.6 cubic m/min/cubic m of maize, required an electrical energy consumption of 0.46-0.9 MJ/kg water evaporated of 16-27 baht/t of maize.
