Geometric and gravimetric characteristics of black gram
Study of physical properties are necessary to determine the appropriate equipment design for processing transportation, separating, storing and drying systems. In this experimental study, some raw material characteristics were determined for the blackgram to get the idea for proper equipment design . The average length, width and thickness were found to be 3.53mm, 2.22mm and 2.29mm at 11.11% moisture content respectively for the dry seeds. The geometric mean diameter, arthimetic mean diameter,equivalent mean diameter, thousand grain weight, sphericity, aspect ratio, surface area and volume were 2.612mm, 2.679mm,4.24mm,40.6g, 74.35%,65.5%, 21.591mm2 and 9.56mm3 respectively. True density, bulk density and porosity were 1335.08 kg/m3,805.091kg/m3 and 39.697% respectively.
