Determination of some physical and mechanical properties of pea (Pisum sativum L.) seeds

Abstract

In the present study some physical properties of pea seeds at different moisture content (4.47 to 61.23%) were estimated. The results revealed that mean values of seed length, width, thickness, geometric mean diameter, sphericity, seed weight and volume were 9.42, 6.71, 7.42, 8.43 mm, 85.0%, 0.32 g and 0.20 cm3, respectively. As moisture content increased from 4.47 to 61.23%, true density, porosity, projected area and terminal velocity were raised from 1480 to 1990 kg m-3, 62.0 to 75.0%, 52.34 to 91.46 mm2 and 7.67 to 9.75 m sec-1, respectively. Furthermore, bulk density was decreased from 600 to 490 kg m-3 for the same moisture content range. © 2006 Asian Network for Scientific Information.
