Variations in physical properties of brown rice using laboratory scale polisher

Abstract

This study has investigated the relationships between physical properties (length, width, thickness, aspect ratio, equivalent diameter, sphericity, bulk density, true density, hardness, terminal velocity, angle of repose and porosity) and degree of milling (DOM) of Chingure variety brown rice during milling& polishing process. The physical properties make significantly different contributions to Degree of Milling, milling process ranging from 0 to 120 s. Among the physical properties investigated, length, width, diameter, bulk and true density played an important role in controlling DOM.
