| Abstract | ||||
| The present study was conducted to develop a threshing unit for a sunflower thresher. Experiments were carried out to evaluate the developed thresher at drum speeds of 400, 500 and600 rpm (8.36, 10.79 and 12.54 m/sec) and four levels of moisture content 10.2, 12.5, 15 and 18.7 %. The performance was evaluated in terms of output seed damage, undamaged seeds, threshing losses, threshing efficiency and cleaning efficiency. The lowest seed damaged and threshing losses of 2.6 and 3.25 % were obtained at drum speed of 400 rpm (8.36 m/sec) and moisture content of 10.2 %. The highest undamaged seeds, threshing efficiency and machine productivity of 97.4, 94.15 % and 306.12 kg/h respectively were obtained at drum speed of 600 rpm and moisture content of 10.2 %. | ||||
