| In castor oil extraction process, the bean coat is abrasive to the equipment and releases substances that modify the oil color, reducing its quality. A potential solution would be to run the extraction by compressing only the endosperm. Due to lack of information, the objective of this study was to evaluate the influence of forced air drying at 40, 60, 80 and 100 ºC and farmyard drying, in the mechanical properties of the beans, aiming to break the bean coat. Castor beans were subjected to compression tests, in two perpendicular directions, at a strain rate of 0.6 mm.s-1. Average values of force, deformation energy, strain, all at rupture, and stiffness were used to evaluate the effects of dehydration. It was observed that the heat treatments did not alter... |

| 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%,... |
