“…1). Singh and Goswami (1996) for cumin seeds found such linear relationship between thousand seed/kernel weight and moisture content. The weights of 1000 seeds and kernels at 6.5% db moisture content were in the range of 22-229 and 19-177 g, respectively for pumpkin seeds and kernels (Joshi et al 1993).…”

“…Joshi et al (1993) also reported a linear decrease in porosity with increase in pumpkin seed moisture content. However, Singh and Goswami (1996) found the porosity of cumin seed to increase with grain moisture content.…”

“…True density of minor millets was found to be less than that of gram (Dutta et al 1988). Suthar and Das (1996) noted an increase in the true density from 1010 to 1134 kg/m 3 and 1047 to 1134 kg/m 3 for karingda kernel and cumin seed for the moisture range of 5-40% db and 7-22% db, respectively (Singh and Goswami 1996). Many researchers have reported the decrease in true density with moisture content increase (4-32.6% db) for karingda seed (Suthar and Das 1996), chick pea seeds (Konak et al 2002) and rapeseed (Calisir et al 2005).…”

“…The reason for increased friction coeffi cient at higher moisture content may be due to water present in grains offering increased adhesive force on contact surface. Among various contact surfaces, galvanised iron and mild steel offered higher coeffi cient of static friction as compared to stainless steel and aluminium for cumin seed (Singh and Goswami 1996) and rapeseed (Calisir et al 2005). However, the effect of moisture content was found greater than the contact surfaces for pumpkin seed and kernel (Joshi et al 1993).…”

Physical properties including 1000 kernel weight, bulk density, true density, porosity, angle of repose, coeffi cient of static friction, coeffi cient of internal friction and grain hardness were determined for foxtail millet, little millet, kodo millet, common millet, barnyard millet and fi nger millet in the moisture content range of 11.1 to 25% db. Thousand kernel weight increased from 2.3 to 6.1 g and angle of repose increased from 25.0 to 38.2 o . Bulk density decreased from 868.1 to 477.1 kg/m 3 and true density from 1988.7 to 884.4 kg/m 3 for all minor millets when observed in the moisture range of 11.1 to 25%. Porosity decreased from 63.7 to 32.5%. Coeffi cient of static friction of minor millets against mild steel surface increased from 0.253 to 0.728 and coeffi cient of internal friction was in the range of 1.217 and 1.964 in the moisture range studied. Grain hardness decreased from 30.7 to 12.4 for all minor millets when moisture content was increased from 11.1 to 25% db.

“…The tilting surface was raised gradually by means of a screw device; the angle of tilt (α, degree) at which the cylinder with seeds just began to slide down was recorded as the angle of static friction between the experimental materials (palm fruits, seeds and seed coat) and the friction surface. Adjustable tilting table method has been used for other grains and seeds by other researchers to obtain the coefficient of static friction (Singh and Goswami, 1996).…”

A b s t r a c t. In this study some physical properties of fan palm (Washingtonia robusta) fruits, seeds and seed coats were determined using dimensional, bulk and single kernel physical analysis. The moisture content of whole fruits, seeds and seed coats was 12.0, 9.86 and 13.87% (d.b.), respectively. The sphericity values showed that seed shape (0.86) is close to a sphere, similar as the fruit shape (0.83), both of which were close to a scalene ellipsoid shape. The surface area values of fruits and seeds were obtained as 163.27 and 80.25 mm 2 , and volume values were obtained as 190.96 and 66.32 mm 3 , respectively. Bulk densities of fruits, seeds and seed coats were 559, 783 and 272 kg m -3 , and the corresponding true densities were 1143, 1147 and 864 kg m -3 , whereas the corresponding porosities were 48.87, 54.12, and 31.52%, respectively. The values of the static coefficient of friction and the angle of repose of fruits, seeds and seed coats of palm fruits were studied on aluminium, canvas, galvanised iron, plywood, PP knitted bag, PVC and stainless steel surfaces. As expected, seed coat has higher values of coefficient of static friction on the all surfaces than fruit and seed.

The investigation was intended to examine the influence of selected moisture levels (4.26, 12.66, 25.31, 37.89, 50.21% wet basis) on engineering properties namely, dimensional, gravimetric, frictional, aerodynamic as well as mechanical properties of five selected varieties of sesame seed namely GT‐3, GT‐4, GJT‐5, GT‐6, and TKG 22. The investigation finds out that fluctuations in moisture level significantly (p ≤ 0.05) influenced the engineering properties assessed. Increase in moisture content influenced a rise in length, width, thickness, geometric mean diameter, arithmetic mean diameter, sphericity, volume, volumetric expansion coefficient, elongation ratio, flakiness ratio, surface area, projected area, thousand seeds weight, compressibility index, Hausner ratio, angle of repose, coefficient of friction, terminal velocity and Reynolds number of selected sesame verities. Whereas, a reverse trend was observed in aspect ratio, true density, bulk density, tapped densities, drag coefficient, and hardness with moisture content variation. The frictional characteristic of the seed showed improved stability with less flow ability at higher moisture levels. These outcomes disclosed that variation of seed moisture content is authoritative during designing and construction of machinery and process equipment related to sesame. It may be also beneficial in computation of design for hoppers, silos, conveyors, drying, and heat transfer equipment as well as other sesame seed‐related process and handling equipment.
