The objective of this research was to evaluate and compare the performance of three different strategies for aeration of grain corn. The strategies investigated were: continuous aeration, night aeration, and aeration in equilibrium moisture content between the grain and the ambient air. Corn at two different moisture content levels, 11% and 17% were used. Continuous monitoring of grain temperature through sensors was carried out, and grain samples were taken during the experiments for determination of moisture content. All used aeration strategies favored temperature reduction in dry (11%) and moist (17%) grains. The continuous aeration strategy was the most efficient in wet grains, since heating of grains during storage was avoided. No aeration strategy maintained the homogeneous temperature inside the grain during the storage; it varied according to climatic conditions. The moisture content of grains has suffered variations during the experimental period, with a tendency of drying at the end of the process.314745759Benedetti, B.C., (1992) Investigation into the processes of heat and moisture transfer in stored maize, 1992, , 266f.
