SIMULATION OF GRAIN DRYING IN NATURAL-CONVECTION DRYER

All the works so far on simulation of grain drying by natural convecti on of air presents conflicting results on the drying time forecast. In this work the models of Hukill, Thompson and Michigan are tested in s ame type of dryer. Appropriate equations are developed to correct the drying time, starting from the models of Thompson and Hukill. The solu tion of the equations of Michigan model is developed on finite differe nce and similarly some special techniques are utilized on the Thompson model. 53 test results are utilized here to validate the simulation m odel of drying.
