| The morama bean (Tylosema esculentum) is an underutilised legume native to the Kalahari region of Southern Africa. Some engineering properties relevant to the mechanisation of its processing have been characterised, namely; size, shape, surface area, projected area, volume, density, porosity, 1000-grain mass, static angle of repose, static coefficient of friction and texture. At moisture content of 7.4% (w.b.), the average length, width and thickness of the beans were 19.25, 17.21 and 13.39 mm, respectively. Geometric mean, equivalent diameter and arithmetic mean diameters were 16.4, 16.51 and 16.61 mm, respectively. Morama beans are spherical in shape, having average sphericity of 85.45%, aspect ratio of 0.90 and flakiness ratio of 0.78. Surface... |

| Some moisture-dependent physical properties of sour-sop seed were investigated. Results of experiments on rewetted sour-sop seed showed increasing in length, width, thickness, arithmetic and geometric mean diameter, volume, surface area, sphericity, and 1000 seeds weight from 14.91-15.69, 8.71-9.24, 5.39-5.56, 9.67 - 10.16, 8.81 - 9.27 mm, 0.57 – 11.67 cm3, 244.98 - 270.89 mm2, 0.56 - 0.59 and 255.7 – 285 g, respectively within moisture range of 8 – 32.5% (db). An increasing trend for bulk density and true density was observed from 0.52 – 0.59 g/cm3 and 0.47 – 0.60 gcm-3. Porosity of the seed decreased from 9.62 – 4.73 %. Angle of repose was increased linearly from 25.7 – 33.3o with increase in moisture content from 8.0 – 32.5% (db). At all moisture... |
