dc.description.abstract <p>A computer simulation model was developed to model summer preparation of desiccant corn using heat from solar collectors. The desiccant provides a storage medium for solar energy in the form of drying potential and is blended with wet corn at harvest. Grain-mass/collector-area ratios from 0.27 to 8.5 t/m2 (1.0 to 31 bu/ft2) and airflow rates from 0.0019 to 0.093 m3/s-t (0.1 to 5 cfm/bu) were studied. The use of a solar collector during the summer is desirable because solar radiation is available more hours per day, the drying potential is good, and the solar collector use period is increased. The desiccant corn is blended with wet corn in the fall to reduce the average moisture content of the wet corn, therefore reducing the electrical energy to dry and reducing the spoilage risk of the wet corn. Based on the simulation results, an airflow rate of 0.014 m3/s-t (0.75 cfm/bu) along with a grain-mass/collector-area ratio between 3 and 5.5 t/m2 (11 and 20 bu/ft2) is recommended. This airflow rate and the grain-mass/collector-area ratio range will achieve a corn desiccant moisture of 8 to 10% with an acceptable collector size and electrical energy input.</p>
