Effect of moisture content on angle of repose for different cereals and pulses

Abstract

The study was conducted on “Effect of Moisture Content Effect of Moisture Content on Angle of Repose for different cereals and pulses” Physical property, i.e. moisture content and angle of repose were measured. The main aim of the study was to study the effect of moisture content on the angle of repose for selected cereals and pulses and to develop the prediction model to quantify the effect of moisture content on angle of repose. The variable observed were moisture content as independent variables while angle of repose is observed variable. The grains used were paddy, maize, Bengal gram, soybean and pea. Five levels of moisture content were considered 8%, 10%, 12%, 14% and 16% (d.b.). In this method, angle of repose is measured by measuring slope with horizontal pile formed on the free vertical fall of the grains. In all the cases the prediction model having nature of straight line function was generated to characterize the relationship between moisture content and angle of repose and angle of repose. The angle of repose increased as moisture content of the grains increased. In this study straight line function shows best relationship in between moisture content and angle of repose for paddy, maize, bengal gram, soybean and pea.
