摘要: To design the planting, separating, threshing, sizing and packing machines for agricultural products, physical mechanical properties of products should be known. In this paper, some red radish seeds were studied. Dimensional parameters, when moisture content equals to 5.65% based on dry bases (d.b), measured using image processing technique. Effects gravimetrical frictional seeds, including mass single seed, 1000-unit bulk density, true porosity, static coefficient friction various surfaces, angle repose pouring, Hele-Shaw, empting filling methods volume container (150, 350, 550 750 mL) height fall density porosity (d.b) Also length, width, thickness distributions modeled Gamma, Generalized Extreme Value Weibull distributions. Results showed that width ranged from 0.660 0.900 mm, 0.524 0.763 mm 0.490 0.759 respectively. With increasing 150 mL, increased; but with decreased. 5.65 21.71% , decreased 694.807 654.889 kg/m3 1141.810 1057.795 kg/m3; increased 6.98 7.17 g.
