| 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... |

| The performance evaluation of an existing kenaf decorticator was carried out in this study. A field was planted with kenaf at the Teaching and Research Farm (T&RF) of the Obafemi Awolowo University, Ile Ife. The field was maintained and monitored until the kenaf was 10 weeks old when the evaluation of the machine commenced. The kenaf decorticator was evaluated using different operation parameters, which include plant age (10, 11 and 12 weeks after planting), kenaf stem size (small, medium and large) and decorticator speeds (520, 600 and 680 rpm) giving rise to a 3 by 3 factorial experiment. The result showed that the highest mean of throughput value... |
