Equation of motion of the point of the paddy mound in the dryer drum

During the drying process, the more time the paddy pile is in the dryer, the higher the drying efficiency of the device. Thus, the movement of the paddy along the OX axis is one of the main factors affecting the drying efficiency of the device. Paddy movement along the OX axis depends on the speed of the drying agent. Therefore, in experimental studies, it is advisable to determine the optimal value of the speed of the drying agent in the range from 0,25 m/s to 0,75 m/s. The number of revolutions of the dryer drum provides mixing of the paddy mound. The mixing of the paddy during the drying process is one of the factors that leads to an increase in the drying efficiency of the device. Therefore, it is advisable to determine the optimal value of the number of revolutions of the dryer drum from 16 min -1 to 22 min -1 .
