In this stage, the initial moisture content of the product decreases. Achieving optimal conditions in the drying process can have an important effect on the processing time and improving the quality indicators of the product. Temperature parameters and hot air movement speed are the main effective factors in soybean drying process. In this study, the effect of temperature changes (at three levels of 40, 50, and 60 degrees Celsius) and air velocity at two levels (2 and 3 m/s) on the drying time and rate of soybeans was investigated. Changes in humidity during the drying process in different conditions were fitted with different mathematical models. The results showed that the parameters of temperature and air movement speed have significant effects on the drying time and speed at the probability level of 1%. The effect of temperature on the drying process was very high and its increase decreased the drying time and increased the drying rate.
