| A soybean threshing machine was designed, fabricated and evaluated at Landmark University, Omu-Aran, Kwara State, Nigeria, to determine its performance and ease the drudgery problems associated with threshing of soybean by the small scale farmers. Evaluation was carried out with TGX 1448 soybean variety at different levels of moisture contents; 10%, 16% and 22% (wet basis) and at different drum speeds; 320 r/min, 385 r/min, 450 r/min, 515 r/min, with constant mass input of 600g and constant concave clearance of 23 mm. The overall mean results obtained for performance indicators in terms of threshing efficiency, cleaning efficiency, percentage of damage seed, percentage of blown seeds, percentage of seed loss and throughput capacity were 99.51%, 77.91%,... |
