| Abstract | ||||
| Some properties of sugar beet seed species were determined to utilize for design and develop the precision planter, handling process and cleaning systems. The main dimensions (length, width and thickness), spherisity, geometric mean diameter, arithmetic mean diameter, surface area, bulk density and true density were identified as physical parameters. Meanwhile, the terminal velocity, and hardness were measured as engineering properties. Results of the above investigated parameters showed that the mean of sugar beet seed properties data were 6.12 mm, 5.30 mm, 4.08 mm, 7.22, 44.59 mm, 5.17 mm, 204.97 mm2, 0.277 g/cm3, 4.62 g/cm3, 1.66 m/sec and 17.64 N respectively for multi-germ species. But, the same data at mono-germ were 4.34 mm, 4.14 mm, 3.82 mm, 5.28, 22.94 mm, 4.10 mm, 112.96 mm2, 0.439 g/cm3, 0.747 g/cm3, 3.049 m/sec and 23.29 N respectively. The mean values for the coefficient of friction were 0.4765, 0.5108, 0.5704 and 0.7276 on stainless steel, iron sheet galvanized, plastic and rubber matrials respectively for multi-germ seeds. Furthermore, the mean values for the coefficient of friction were 0.2609, 0.2894, 0.3027 and 0.3537 on stainless steel, iron sheet galvanized, plastic and rubber matrials respectively for mono-germ seeds. | ||||
