| This study was conducted to investigate physical, mechanical and chemical properties of Garlic white (Allium sativum L.) for bulb and clove. The considered parameters were length, width, thickness, mass , volume, solid density, bulk density, porosity, Arithmetic mean diameter, Geometric mean diameter, sphericity, packaging coefficient, Surface area, projected area, coefficient of static friction with different surfaces (wood , glass, rubber, steel, fiber, plastic), angle of repose (empty , filling), rubbing force and rupture force. The average values of properties, measured at a moisture content of 12.97 ± 0.30% (dry basis): for garlic bulb, length, width, thickness, mass , volume, solid density, bulk density, porosity, arithmetic mean diameter, geometric mean diameter, sphericity, packaging coefficient, surface area and projected area, were 59.9 mm, 58 mm, 45.2 mm, 62.5 g, and 103.5 cm3, 0.61 g/cm3 , 0.45 g/cm3, 25.9 %, 54.4 mm, 53.85 mm, 0.90, 0.97, 91.4 cm2 and (50.05/42.27) cm2 respectively. The same value for garlic clove were 26.4 mm, 11.9 mm, 8.5 mm, 1.49 g, and 4.39 cm3, 0.94 g/cm3 , 0.57 g/cm3, 39.6 %, 15.6 mm, 13.7 mm, 0.53, 0.46, 6.1 cm2 and (2.66/0.5) cm2 respectively. The coefficient of static friction of bulb and clove on various surfaces showed that static friction on rubber is higher then on other surfaces and static friction on fiber is the lowest. Angle of repose of bulb and clove were higher when applying the filling method than when applying the empting method. It was also noticed that angle of repose of clove for both methods was higher than for bulb. The rubbing force ranged from 8.99 to 14.5 kg. While the rupture force of the clove ranged from 2.5 to 13.54 kg. | ||
