“…The experimental results demonstrate that the static coefficient of friction values for the three varieties significantly increased with the increasing moisture content on all surfaces (P<0.05). Similar studies have reported the effect of moisture content on the static coefficient of friction: Altuntas and Yildiz (2007), Milani et al (2007) and Sologubik et al (2013) for faba bean, cucurbit seeds and barley, respectively. The increase in the static coefficient of friction with the moisture content may be due to the increased adhesion between the seed and the material surface at higher moisture values.…”

“…The variation in bulk density with the moisture content was found to be significant (P<0.05). The decrease in the bulk density of the kenaf varieties with the increasing moisture content may be due to the increase in mass, owing to the moisture gain in the sample being lower than the corresponding volumetric expansion of the bulk (Sologubik et al 2013). The relationship of the bulk density of the kenaf varieties with respect to the moisture content can be represented by the equations provided in Table 3.…”

“…The moisture-dependent characteristics of the physical properties of agricultural products have effects on the adjustment, performance efficiency and energy consumption of processing machines. In recent years, many researchers have reported the moisture dependence of the physical and mechanical properties of chosen agricultural materials, such as wheat (Tabatabaeefar 2003), linseed (Selvi et al 2006), sorghum seed (Mwithiga and Sifuna 2006), tef seed (Zewdu and Solomon 2007), watermelon seed , red lentil seed (Gharibzahedi et al 2011) and barley (Sologubik et al 2013).…”

The physical properties of three kenaf varieties were evaluated as a function of moisture contents varying from 7.67 to 26.21, 7.35 to 25.96 and 7.27 to 25.53 % (dry basis) for cv. Everglades, Tainung and SF-459, respectively. The results showed that the increase in the moisture content of the kenaf seeds linearly decreased the bulk density, true density and rupture force, whereas it linearly increased the length, width, thickness, arithmetic mean diameter, geometric mean diameter, sphericity, surface area, seed volume, thousand seed mass, porosity, angle of repose and terminal velocity. Among the three varieties, maximum values for most selected physical properties of kenaf seeds were obtained for the Everglades seeds. At all moisture contents, the highest static coefficient of friction was found on the plywood surface followed by rubber, then galvanized iron, aluminum, glass and finally stainless steel. This study was conducted to investigate some moisturedependent physical properties of kenaf seeds. These physical properties are necessary for the design of equipments for harvesting, processing, transportation, sorting, separating and packing.

“…Physical attributes of germinated and non-germinated cultivated radish seeds from the graded and discarded fractions simple cleaning machines can be used interchangeably with no negative effect on separation efficiency. Strong relationships between seed attributed are desirable because they facilitate the design of processes and operations related to seed sowing, harvesting, storage and processing (Altuntas, Demirtola, 2007;Kabas et al, 2007;Riyahi et al, 2011;Sologubik et al, 2013), and enable simplification of the mathematical description of the above models. Interestingly, a significant correlation was also observed between the angle of external friction and the remaining parameters of cultivated radish seeds.…”

Relationships between the physical properties of seed and their germination capacity and energy is an important consideration for separating seeds of the highest or lowest quality. The objective of this study was to determine the correlations between the selected aerodynamic, geometric, frictional and mass parameters of cultivated radish (Raphanus sativus L.) seeds and their germination capacity for the purpose of improving seed quality. The parameters were determined for graded and discarded radish seeds and impurities were separated by a gravity separator. A germination test was performed, its results were verified every 12 hours, and the germination rate index was determined. A statistical analysis revealed that germinated and non-germinated seeds from the graded fraction did not differ significantly. In the discarded fraction, germinated seeds were characterized by higher terminal velocity (by approx. 10%), thickness (by approx. 9%) and mass (by approx. 26%) in comparison with non-germinated seeds. Significant positive correlations were noted between the germination time vs terminal velocity and mass of discarded seeds. Thus, the separation of radish seeds should take place in two stages using a gravity separator and a pneumatic separator. A vertical stream of air with the speed of approx. 8 m s -1 allows recovery of around 37% of discarded seeds that contain approx. 86% of healthy germs. The resulting seed mixture is characterized by greater germination energy and capacity than the seed fraction graded on a gravity separator only.

This research focuses on yellow lentil seeds and determining the effects of moisture content on some of their physical properties. The various types of machinery used in gathering crops, processing, shipping, categorizing, sorting, and packaging are designed according to the physical properties of the specific crops. When the moisture content increased from 15.6% to 22.5% d.b., the bulk density decreased from 750.27 to 625 kg m -3 , the true density increased from 1200.5 to 1334 kg m -3, and the rupture force decreased from 2.5 to 16.2 N. Under the same conditions, the measurements of the average thickness, diameter, arithmetic mean diameter, geometric mean diameter, projected area, surface area, sphericity, thousand seed mass, porosity, and terminal velocity values varied as follows: from 1.22 to 1.42 mm, 4.29 to 4.6 mm, 3.26 to 3.53 mm, 2.82 to 3.1 mm, 15.33 to 17.66 mm
