Abstract
This project work is on Assessing the impact of air humidity on the drying of freshly harvested corn. The effect of air humidity of 10%, 20%, 30%, 40% and 50% on the drying of freshly harvested corn was assessed. The freshly harvested corn was weighed and dried differently in drying environments of air humidity of 10%, 20%, 30%, 40% and 50% and temperatures of 320c, 340c, 350c, 360c and 380c respectively using the dry and wet bulb thermometers. The corn samples were assessed for drying rates in intervals of 3 days until 21 days by weighing and re-weighing the samples. The result showed that for relative humidity of 10% the drying rates were 1.0×10-3, 1.6×10-3, 1.7×10-3 20×10-3, 2.7×10-3, 3.3×10-3, 4.0×10-3kg/day for the intervals. For 20% relative humidity, the drying rates were 1.0×10-3, 1.3×10-3 1.7×10-3, 2.0×10-3, 2.3×10-3, 3.3×10-3 and 4.0×10-3kg/day,For 30% relatively humidity, the drying rates were 4.0×103, 4.7×10-3, 5.3×10-4, 5.7×10-3, 7.3×10-3, 8.0×10-3, 8.7×10-3,For 40% relative humidity, drying rate were 5.3×103, 6.0×0-3 6.7×10-3, 7.3×10-3, 8.0×10-3, 8.7×10-3, 9.3×10-3, For 50%, drying rates were 5.3×10-3, 6.7×10-3, 7.3×10-3, 8.0×10-3, 9.3×10-3, 10.7×10-3, 11.3×10-3 50% relative humidity drying condition has the highest drying rates.
