✦ Synopsis

The physical properties of arecanut kernels were determined in the moisture range from 88Á91 to 10Á51% d.b. The kernel shape can be treated as ovate. As the moisture content decreased from 88Á91 to 10Á51% d.b., the dimensions of the major, medium and minor axes decreased by 10Á45, 10Á49 and 22Á84%, respectively. The mean values of roundness and sphericity of the kernel decreased by 5Á69 and 8Á13%, respectively, as the moisture content decreased from 88Á91 to 10Á51% d.b. One hundred kernel weights of arecanut were 1Á159 and 0Á594 kg at moisture contents of 88Á91 and 10Á51% d.b., respectively. The bulk and true densities increased linearly whereas the porosity and angle of repose decreased linearly as the moisture content decreased from 88Á91 to 10Á51% d.b. The static and kinetic coefficients of friction were maximum on mild steel surface and the values on mild steel, galvanized iron, aluminium, stainless steel and hard board decreased curvilinearly from 88Á91 to 30Á24% d.b. and afterwards the values increased.
