✦ Synopsis

Some physical properties of shea kernels were determined in order to design equipment and facilities to process &shea butter', an important vegetable fat made from shea kernels. At a moisture content of 4)35% d.b., the average length, width and thickness of shea kernel were 31)50, 23)70 and 22)00 mm, respectively. The average geometric mean diameter sphericity and density were 2)52 cm, 0)80 and 1)17 g/cm, respectively, while the static coe$cient of friction varied from 0)36 on plywood with grain parallel to direction of motion to 0)52 on galvanized steel. The angle of repose was 343. 2000 Silsoe Research Institute Notation D C geometric mean diameter, mm ¸length of kernel, mm S surface area of kernel, cm ¹ thickness of kernel, mm = width of kernel, mm sphericity of kernel
