To study the Physico-chemical properties of Lathyrus sativus

Abstract

The physical and mechanical properties are important for developing primary processing machinery. The geometric properties such as size and shape, equivalent diameter, sphericity, surface area, volume are the important physical properties used in developing machineries for separation and cleaning. The present study was undertaken to the axial dimension of Lathyrus sativus (Var. Mahateora). The four levels of moisture content were taken at 7.78, 9.54, 11.61 and 14.86 percent (dry basis).The average value of length; width and thickness were varied from 5.20 to 5.24 mm, 4.29 to 4.70 mm and 3.51 to 4.05 mm respectively. While the bulk density and true density was decreased from 848.84 to 794.44 kg/ , 1218.32 to 1130.50 kg/ . The surface area by equivalent diameter, surface area by axial dimension and porosity was found to be 55.85 to 67.75 , 50.83 to 62.27 and 30.84 to 31.46 percent. The angle of repose and coefficient of friction was varied in the range of 22.41 to 29.02 and plywood plate, galvanized iron plate and rubber plate surface were found to be varied 0.41 to 0.55, 0.45 to 0.58, 0.63 to 0.72 respectively. The proximate composition of Lathyrus sativus split dhal was observed the protein, fat, total ash, carbohydrate and fiber content as 22 percent, 2.3 percent, 2.90 percent, 60.00 percent, 3.94 percent respectively.
