STUDIES ON PHYSICAL PROPERTIES OF PEANUTS POPULAR IN SAURASTRA REGION

Physical and mechanical properties of peanut kernels are important to the researcher, design engineer, the food industry. The present study aimed to determine and recognize a database of physical and engineering properties of peanut seed which play an important role in designing and developing of specific machines and their operations such as planting, harvesting and grading. The physical properties namely Moisture content, % (w.b), Length (mm), Width (mm), Thickness (mm), Shape, Sphericity (mm), 100 kernels weight (mm), Geometric mean diameter (mm), Surface area (mm2), Aspect ratio (%), True density (kg/m3), Bulk density (kg/m3), Porosity (%), Angle of repose, degree, Terminal velocity (m/s), Coefficient of friction (Wood, Glass and GI surface) and Germination percentage (%) of peanuts variety kernel GG-20 and TG-37A were investigate and reported in this study. Size distribution of GG-20 and TG-37A peanut kernels also studied.
