“…This order has been reported for pumpkin seeds (Joshi et al, 1988); cumin seeds (Singh and Goswami, 1996); sunflower (Gupta and Das, 1997), bambara groundnuts (Baryeh, 2001) and sweet corn (Karababa and Coşkuner, 2007). However, Amin et al (2004) Dutta et al (1988) for gram seed, Joshi et al (1988) for pumpkin seeds, Carman (1996) for lentil seeds, Öğüt (1998) for white lupin and Aydin (2002) for hazel nuts reported that as moisture level increased, static coefficient of friction increased. This is because, the seeds may become rough and static coefficient of friction is increased.…”

“…Carman (1996), Gupta and Das (1997), Kibar et al (2010), Visvanathan et al (1996) and Aviara et al (2014a) found the bulk density of lentil (Lens culinaris) seeds, sunflower seeds, Mucuna flagellipes nuts, rice (Oryza sp.) seeds, neem (Azadirachta indica) nuts, and Brachystegia eurycoma seeds, respectively, decreased as the seed moisture content increased.…”

“…Carman (1996), Ebubekir et al (2004), Sessiz et al (2007) and Aviara et al (2010) reported a linear increase in the kinetic coefficient of friction for lentil seeds, fenugreek (Trigonella foenum-graceum) seeds, caper (Capparis spinosa) fruits, and Mucuna flagellipes nuts with moisture content, respectively. The value of kinetic coefficient of friction is an essential factor in the determination of the power required for continuous flow of granular or unconsolidated materials.…”

Purpose: Physical properties of Detarium microcarpum seeds were investigated as a function of moisture content to explore the possibility of developing bulk handling and processing equipment. Methods: Seed size, surface area, and 1,000-seed weight were determined by measuring the three principal axes, measuring area on a graph paper, and counting and weighing seeds. Particle and bulk densities were determined using liquid displacement and weight in a measuring cylinder, respectively. Porosity was computed from particle and bulk densities. Roundness and sphericity were measured using shadowgraphs. Angle of repose and static and kinetic coefficients of friction were determined using the vertical cylindrical pipe method, an inclined plane, and a kinetic coefficient of friction apparatus. Results: In the moisture range of 8.2%-28.5% (db), the major, intermediate, and the minor axes increased from 2.95 to 3.21 cm, 1.85 to 2.61 cm, and 0.40 to 1.21 cm, respectively. Surface area, 1,000-seed weight, particle density, porosity, and angle of repose increased from 354.62 to 433.19 cm 2 , 3.184 to 3.737 kg, 1060 to1316 kg/m 3 , and 30.0% to 53.1%, respectively, whereas bulk density decreased from 647.6 to 617.2 kg/m 3 . Angle of repose increased from 13.9° to 28.4°. Static and kinetic coefficients of friction varied between 0.096 and 0.638 on different structural surfaces. Conclusions: Arithmetic mean, geometric mean, and equivalent sphere effective diameters determined at the same moisture level were significantly different from each other, with the arithmetic mean diameter being greatest. Surface area, 1,000-seed weight, particle density, porosity, and angle of repose all increased linearly with moisture content. Bulk density decreased linearly with moisture content. The coefficients of friction had linear relationships with moisture content. The highest values of static and kinetic coefficients of friction were observed on galvanized steel and hessian fabric, respectively, whereas the lowest values were observed on fiberglass.

“…The samples were kept in a refrigerator at 5°C (±1°C) for 7 days for the moisture to distribute uniformly throughout the seed (Carman 1996). The moisture content of samples after equilibration was determined before each test was conducted.…”
