The physical properties of different varieties of lathyrus viz., Ratan, Pratik, Mahateora, were studied at moisture content of 7.90 to 19.40, 6.75 to 18.30, 9.48 to 21.02, 9.79 to 21.34, 9.52 to 21.04, 9.03 to 20.61, 9.91 to 21.49, 9.22 to 20.83, 9.42 to 21.03 and 9.10 to 20.71% (d.b.). The grain size, thousand grain weight and angle of repose, were found increased linearly and the average increase was found to be 8.07, 15.11 and 21.32%, respectively, with the corresponding increase in moisture content. The sphericity and porosity increased initially and then found decreased with further increase in moisture content. The bulk density and true density values decreased linearly and the average decrease was found to be 15.01 and 13.71%, respectively.

“…On the other side, the sample weight of bean is much greater than of lentil. Altuntas and Yildiz (2007) determined the weight of 1000 kernels for faba bean as 1140 to 1332 g, Isik and Unal (2007) the weight of 1000 kernels of kidney bean as 522-560 g. The measured kernel density of our cultivars was higher than those given in the data of Altuntas and Yildiz (2007) and Isik and Unal (2007).…”

“…The size and shape are important in their electrostatic separation from undesirable materials and in the development of sizing and grading machinery. The shape of the material is significant for the analytical prediction of its drying behaviour (Isik & Unal 2007;Altuntas & Yildiz 2007).…”

“…According to Altuntas and Yildiz (2007), faba bean are characterised by kernel density of 1150-1210 kg/m 3 . Isik and Unal (2007) characterised kidney beans by the kernel density of 1230-1390 kg/m 3 . Owing to the irregularities and variations in shapes, surface profiles, and dimensions of specific food materials, it is difficult to evaluate the actual surface areas and volumes.…”

Food Sci., 26: 109-116.Geometrical features of lentil seeds (lens culinaris Medik) were analysed using the image analysis LUCIA system Ver. 3.52. The values of the weight of 1000 kernels, kernel density, specific volume, specific surface area, and surface area of 1000 kernels of red and green lentils were determined as 66.61 and 138.56 g, 1504.5 and 1376.4 kg/m 3 , 0.6647 and 0.7265 cm 3 /g, 0.594 and 0.579 m 2 /kg, 395.4 and 801.9 cm 2 , respectively. The lentil volume was simulated by an oblate spheroid and two sphere segments and the volumes obtained with both models were compared with that obtained by pycnometric method. Percentage differences of the two sphere segment approximation for red and green lentils were 4.4% and 4.2%, respectively. The height (thickness) of lentils was constant and practically the same with both varieties (2.6 mm) and therefore it was possible to simplify the geometrical models. Thus, 2D image analysis is suitable for a quick evaluation of the specific volume and surface area of grains on the basis of the projected area (equivalent diameter) without the measurement of the height. Image processing provides a simple, rapid, and non-invasive methodology to estimate lentil geometric features and engineering parameters.

“…The cracking force found in loading along the thickness lay between 154 and 204 N. Loading on the vertical axis gave the highest resistance to cracking. In their study, Işik and Ünal (2007) observed that the shelling resistance of white speckled red kidney bean grain decreased from 98.26 N to 53.67 N as the moisture content increased. Lately, a similar study was done by Altuntaş and Karadag (2006) in that the mechanical properties of sainfoin, grasspea, and bitter vetch seeds were determined in terms of the average rupture force, specific deformation and rupture energy along X-, Y-and Z-axes.…”

Force and deformation curves of agricultural materials must be provided for the proper design of harvesting and processing machineries. In this research, the fracture resistance of barley grain was measured in terms of the grain rupture force and energy. In this study, 8 treatments were performed as a randomised complete block design with 10 replications. The barley grains were quasi-statically loaded in horizontal and vertical orientations with the moisture content at four levels: 7.34, 12.11, 16.82, and 21.58% dry basis, and loading rates at two levels: 5 and 10 mm/min. Based on the results obtained, the force required for initiating the grain rupture decreased from 161.97 to 93.94 N, and from 75.37 to 50.16 N, and the energy absorbed at the grain rupture increased from 36.42 to 74.70 mJ and from 27.34 to 62.65 mJ, for horizontal and vertical orientations, respectively, with the increase in the moisture content from 7.34 to 21.58% dry basis. This showed that seeds are more flexible in the horizontal orientation.
