Abstract
This research was conducted with two varieties of almond kernel (thin shell and semi stone shell) for five
moisture levels (5%, 10%, 15%, 20%, 25% d.b.) with five replications using completely randomized base
factorial design. The results showed increases with increasing moisture content from 5% to 25% for the
thin shell almond for the following variables: true density (851.12 to 1138.94 Kg/m3); porosity (35.69 to
54.45%), terminal velocity (4.81 to 6.18 m/s); static friction coefficient on Plexiglas (0.471 to 0.591); static
friction coefficient on galvanized iron (0.417 to 0.552); projected area (1.45 to 1.67 m2); repose angle
(18.26° to 27.59°). Corresponding values for the semi stone shell almond were: true density (897.18 to
1123.84 Kg/ m3); porosity (32.09 to 47.22%); terminal velocity (5.35 to 6.53 m/s); static friction coefficient
on Plexiglas (0.368 to 0.458); static friction coefficient on galvanized iron (0.356 to 0.447); projected area
(1.36 to 1.53 m2); repose angle (16.33° to 22.45°). The results also showed that bulk density decreased as
moisture content increased from 5% to 25% for the thin shell (547.26 to 518.76) and semi stone shell (609
to 592.94 Kg/m3).
