| Abstract | ||||
| The performance of threshing machine with different concave sieves were tested and evaluated according to the following parameters: - cylinder speeds (15.14, 18.18, 20.21 and 22.25 m/s), feeding rates (8, 10, 12 and 15 kg/min) and holes diameter of concave sieves (11, 9 and 7mm). The experimental results revealed that both seed output, cleaning efficiency, seed damage, threshing efficiency and consumed power were maximum with cylinder speed of 22.25 m/s and feeding rate of 15 kg/min (8.7 kg/min, 98.99%, 23%, 97.75% and 3.23 kW, respectively). Unthreshed seed losses and length of cut straw were minimum (0.34% and 9.5 mm) under the feed rate 8 kg/min, cylinder speed of 22.25 m/s and hole diameter for concave sieve of 7 mm. The criterion function cost for modification thresher machine was 66.978 LE/Mg at the same operation condition. | ||||
