| Abstract: |
| In this study, some physical properties of fennel seeds (Foeniculum vulgare Mill.) include geometric properties (length, width, thickness, mean geometric and arithmetic diameter, surface area and sphericity coefficient), gravity properties (bulk density and actual density) and static friction coefficient of fennel seeds as a function of moisture content were investigated. The result of the study reveals that the average length, width, thickness, arithmetic and geometric mean diameter at 56.5 % to 12% moisture content (d.b.) decreased from 6.43 to 5.76 mm, 2.21 to 1.86 mm, 1.93 to 1.59 mm, 3.02 to 2.57 mm and 3.52 to 3.07 mm respectively. Also, with decreasing moisture content from 65.5% to 12%, sphericity, bulk density and actual density changed from 0.41 to 0.33, from 338 to 573 kg.m-3 and from 1073 to 897 kg.m-3, respectively. The test results showed that the static friction coefficient decreased with decreasing moisture content, so that the galvanized sheet and wood surfaces with values of 0.34 and 0.65 had the lowest and highest static friction coefficients at the highest moisture levels, respectively. The relationship between physical properties and moisture content is described by some regression equations with high coefficient of determination (R2). |
