Effects of diameter and helical angle of flute on the flow evenness of fluted roller used in seed drills using lentil seed
In this study, the optimum dimensions of flute diameter and helical angle of fluted roller used in seed drills were determined for lentil seeds at 100 kg ha-1 of seed rate. The values of coefficient variation were used to determine the optimum dimensions of fluted rollers. The best rates of flow evenness and the minimum coefficient of variance values were obtained at the flute diameter of 8 and 10 mm, helical angle of 10 and 20 degrees (°).
Key words: Flow evenness, flute diameter, fluted roller, lentil, seed rate, seed drill.
