In this process, by using heat energy, the water in the material is evaporated and a solid, liquid and semi-solid material turns into a solid material with less moisture. Temperature parameters and hot air movement speed are the main effective factors in corn drying process. In this research, drying experiments were conducted at temperatures of 40, 50, 60 and 70 degrees Celsius and air velocity of 2 and 3 meters per second, and the changes in corn moisture during the drying process were fitted with different mathematical models. The results obtained from fitting the tested models in all test treatments show that the logarithmic model has an acceptable fit with the amount of moisture during the drying process in different test treatments.
