Some Physical and Mechanical Properties of Khinjuk

Abstract

Khinjuk is oiling crop; therefore, physical and engineering properties are necessitate to determine for processing and equipment design. In this study, some raw material characteristics were determined for Khinjuk, in order to collect information about identifying some physical and mechanical properties of them. The average grain length, width and thickness were 5.49, 5.09 and 4.08 mm, respectively. The geometric mean diameter, thousand grain kernel and aspect ratio were 5.02 mm, 87.15g and 0.95, respectively. True density, bulk density and porosity were 1.01 kg m^-3, 0.55 kg m^-3 and 45 %, respectively while the static coefficient of friction varied from 0.45 on plywood surface to 0.56 on galvanized iron. The angle of repose for static and emptying were 48.33 and 23.74^o degree, respectively. Whereas the failure force and elongation were 42.49 N and 1.35 mm respectively.
