Physical properties of rapeseed (Brassica napus oleifera L.)

Aerodynamic Characteristics of Unshelled and Shelled Sunflower Seeds: Significance of Moisture and Cultivars

“…[10] It was also noticed when moisture content was increased from 5.0 to 22.5% d.b., terminal velocity for millets increased from 2.75 to 4.63 ms −1 . [11] A similar increasing trend was observed for terminal velocity with an increase in moisture content for rapeseed, [12] almond nut and kernel, [13] and pigeon pea. [14] Gezel et al [15] observed that terminal velocity for apricot kernel and apricot pit followed a linear relationship with their moisture content, and the terminal velocity for apricot kernel was found to be more than apricot pit.…”

Aerodynamic properties of sunflower seed (Helianthus annuus L.)

“…It was also noticed when moisture content was increased from 5.0% to 22.5% d.b., the terminal velocity for millets increased from 2.75 to 4.63 m s À1 (Baryeh, 2002). Similar increasing trend was observed for terminal velocity with increase in moisture content for rapeseed (Calısır, Marakoglu, Ogut, & Ozturk, 2005), almond nut and kernel (Aydin, 2003) and pigeon pea (Baryeh & Mangope, 2003). Gezer, Ulları, and Demir (2003) observed that terminal velocity for apricot kernel and apricot pit followed a linear relationship with their moisture content and terminal velocity for apricot kernel was found to be more than apricot pit.…”

A Simulation Model for Determining the Mechanical Properties of Rapeseed using the Discrete Element Method

“…Considering the largest particle size of 7 mm used in the rapeseed material model, this corresponds to a 6 -7 mm size range with linear distribution. The measured physical parameters agree with the results published in literature [2,18]. The compression curves obtained by applying a feed speed of 500 mm/min are shown in Fig.…”

“…The need to decrease resource requirements and simulation runtime justify the use of specialized models, but their usability for studying the various material phenomena is severely limited. While rapeseed material models designed in previous research were not validated with simulated multi-axis mechanical stresses, it is important to consider such stresses in order to account for the significant normal and shear stresses that occur during the extrusion pressing of rapeseed [18]. In order to investigate these more mechanically complex phenomena, more complex rapeseed models are needed that can be used to analyze multi-axis stresses within the grains.…”
