The aims of this study are to investigate the geometric, volumetric and frictional properties of Juniper berries fruits such as size dimension, sphericity, bulk density, angle of repose, volume, fruit density, porosity, and the static and dynamic coefficients of friction on the different surfaces at a moisture content of 14.07% (dry basis). The mean values of height, diameter, geometric mean diameter and sphericity were 7.82 mm, 8.60 mm, 8.31 mm 96.66%, respectively. The bulk and fruit densities, angle of repose, porosity, fruit mass and fruit volume values were found as 105,8 kg m-3, 816.4 kg m-3, 28.61°, 86.97%, 0.23 g and 283.11 mm3, respectively. The mean values of static and dynamic coefficient of friction against galvanized steel, chipboard, plywood, mild steel and rubber surfaces were determined and the highest static and dynamic coefficients of friction values of juniper berries were found for rubber surface.
