Comparison of some engineering properties of rapeseed cultivars

Comparison of the Mechanical Behaviour of Selected Oilseeds under Compression Loading

“…Comparing this results with previous studies on the mechanical behaviour of one seed under compression loading where unit deformation energy, rupture force and rupture compressive stress were determined, the results obtained in the present study were in agreement with the pressing of rapeseed Unal et al, 2009), jatropha seed (Karaj and Muller, 2010;Sirisomboon et al, 2007), sunflower seed (Gupta and Das, 2000;Perez et al, 2007). Also the position of oil points on the deformation characteristics of the various oilseeds corresponds to similar studies reported by (Faborode and Favier, 1996;Figueiredo et al, 2011;Sayyar et al, 2009) and also the shapes of deformation characteristic are significant to the characteristics described by (Gupta and Das, 2000;Herak et al, 2010;Kabutey et al, 2011;Rusinek et al, 2007),…”

“…1, it is seen that moisture content is an important parameter which can influence the mechanical behaviour of oilseeds, that is, moisture content can cause transformation of deformation characteristic (Karaj and Muller, 2010;Sirisomboon et al, 2007;Unal et al, 2009) and thus change the maximal and limit deformation as well as deformation energy (Blahovec and Reznicek, 1980;Herak et al, 2010;Kabutey et al, 2011;Koegel et al, 1973). Porosity can also influence the mechanical behaviour of oilseeds (Fomin, 1978;Herak et al, 2011a).…”

“…In the literature, considerable information about the mechanical behaviour of the oilseed crops namely rapeseed Rusinek et al, 2007;Unal et al, 2009); sunflower seed (Gupta and Das, 1997;2000;Isik and Izli, 2007;Perez et al, 2007), and jatropha seed (Herak et al, 2010;Karaj and Muller, 2010;Sirisomboon et al, 2007), have been focused on rupture force and deformation characteristics (Fomin et al, 1978;Herak et al, 2011a;Kabutey et al, 2011;Koegel et al, 1973;Mrema and Mc Nluty, 1985), unlike the mathematical description of the deformation characteristics, limit deformation ratio, maximal deformation ratio, energy ratio and oil point deformation ratio.…”

Comparison of some physical and chemical characteristics of buckwheat (Fagopyrum esculentum Moench) grains

“…For each test, a sample was dropped into the airstream from the top of the air column, and air was blown up the column to suspend the material in the airstream. The minimum air velocity that kept the grain in suspension was recorded using a digital anemometer (Thies Clima, Göttingen, Germany) with a sensitivity of 0.1 m/s (Mohsenin, 1986;Unal et al, 2009). Twenty determinations were made for each sample.…”

“…The importance of physical properties for designing post-harvest processing equipment has been emphasized earlier (Pradhan, Naik, Bhatnagar, & Vijay, 2009;Unal, Isık, Izli, & Tekin, 2008). In recent years, the physical, chemical and nutritional characteristics of various seeds such as buckwheat (Inglett, Rose, Chen, Stevenson, & Biswas, 2010;Kaliniewicz, Markowski, Anders, & Jadwisienczak, 2015;Kan, 2011;Parde, Johal, Jayas, & White, 2003;Steadman, Burgoon, Lewis, Edwardson, & Obendorf, 2001), flaxseed Coskuner & Karababa, 2007), vetch (Yalçın & Özarslan, 2004), lentil (Amin, Hossain, & Roy, 2004;Gharibzahedi, Ghasemlou, Razavi, Jafarii, & Faraji, 2011), sainfoin (Altuntas & Karadag, 2006), cowpea (Kabas, Yilmaz, Ozmerzi, & Akinci, 2007), wheat (Al-Mahasneh, Taha, & Rababah, 2007;Kalkan & Kara, 2011), chia (Ixtaina, Nolasco, & Tomás, 2008), mung bean (Unal et al, 2008), sorghum (Mwithiga & Sifuna, 2006), rapeseed (Unal, Sincik, & Izli, 2009) and sunflower (Ilori, Oradugba, & Raji, 2011) have been studied. As far as we know, there is no detailed study available regarding to the physical, chemical and mineral content characteristics of buckwheat grown in Turkey.…”
