Some Physical Properties of Sesame Seed

In order to design equipment for improved processing of sesame seed (Sesamum indicum L.), some of the physical properties were determined at moisture content of 3·4% w.b. The average dimensions of sesame seed viz., length, width and thickness were 2·80, 1·69 and 0·82 mm, respectively. The average geometric mean diameter, sphericity, surface area and density were 1·56 mm, 0·56, 7·80 mm2 and 1224 kg m−3. The average coefficient of friction varied from 0·39 on glass to 0·54 on plywood, while the angle of repose was 32·0°.
