| Summary: | The article presents the results of the research conducted by the authors on the study of the mechanical damage of paddy (rice) passing through the screw conveyor of the mobile rice drying device. The study of the mechanical damage of paddy (rice) makes it possible to make recommendations to increase the amount of rice, which is a useful product, obtained as a result of mechanical processing of dried rice. 3 batches of 100 grains were taken from the pile paddy. The amount of mechanically damaged rice was determined as a percentage of 100 grains of paddy and the average value was obtained for 3 batches. When the number of revolutions of the screw shaft is 50 min-1, the mechanical damage of paddy (rice) is small, but the transportation of rice in the screw conveyor is found to be reduced. When the number of revolutions of the screw shaft is 200 min-1, the mechanical damage of rice (rice) is high, but the transportation of rice in the screw conveyor is found to be increased.
