The study was conducted to investigate some physical properties of soybean at various moisture levels. The dependence of physical properties of soybean on moisture content was determined. In the moisture range from (wb).The soaked soybean size increased linearly in length ( - mm), width ( mm), and thickness ( - mm) according to final moisture content. In this study, length, width and thickness models based on moisture content are defined as linear models and the regression coefficients (R2 ) related to these models are found between , and respectively. Arithmetic Mean Diameter ( - mm), Geometric Mean Diameter ( - ), Square Mean Diameter ( mm), Equivalent Diameter ( - mm) are computed from the average values of three principal dimensions. In the current study, it was determined that unit volume ( mm3 ), surface area ( mm2 ), 1000 grain weight () and angle of repose ( ) increases as the moisture content of soaked soybean increases. As the moisture content of the soaked soybean increases, the value of sphericity, aspect ratio, bulk density, true density and porosity decreased.
