Determining some physical properties of Azivash (Corchorus Olitorious L.) seed

Abstract

Used Azivash seed in the research has been provided in summer 2013. The samples were cleaned and separated manually and residuals and broken seeds were taken apart it and healthy seed was provided for testing. Then diameter, area of image, and round coefficient, were calculated using image processing application. Mass of 1000 seeds, mass density, real density and porosity percentage, static friction coefficient, repose angle in two modes of fullness and emptiness were measured. Liquid replacement method has been used to calculate density and volume of the seeds. The results showed that a positive relationship between physical properties of Azivash seed including geometric properties (diameter, volume), gravity properties (weight of 1000 seeds, real density and porosity), and frictional properties (stability angle of evacuation) with increased moisture, while a negative relationship between specific mass and increased moisture. Average amounts of diameter, area, volume, round coefficient, weight of sample unit, particle density, and mass density at 7 w.b.% moisture consist of: 2.147 mm, 1.961 mm², 1.483 cm³, 0.74, 0.0014 g, 0.961 and 0.794 g/cm³.
