| Summary: | The article provides information about the device, the principle of operation of the developed dielectric device for sorting rice seeds, the results of determining the design parameters of bipolar electrodes and theoretical studies to substantiate the angle of separation of rice seeds from the surface of the working body and the magnitude of the applied voltage to bipolar electrodes, as well as the coordinates of the axis of the separation plane of the receiving hopper. The results of theoretical studies revealed that with a working body diameter of 350 mm and a frequency of its rotation of 50 min-1 for sorting rice seeds on a dielectric device, it is enough to apply a voltage of about 1500 V to the multipolar electrodes. At the same time, for a clear separation of rice seeds torn off from the working surface into the sowing and technical fraction, the coordinates of the axis of the dividing plane of the receiving hopper should be set from the axis of rotation of the working body at a distance: horizontally 165 mm and vertically 300 mm, with its height 150 mm.
