 ABSTRACT

Physical and engineering properties of agricultural grains are necessary for the design of storage, handling and processing equipment. The present study was undertaken to study dimensional, gravimetric, and frictional characteristics of selected paddy (var. Chhattisgarh Madhuraj, Hanthipanjra and Mahamaya) and its initial moisture content were found 11.81 %, 11.23 %, and 11.05% on wet basis. In paddy varieties the average values of length were 8.47 mm, 11.15 mm, 9.40 mm and width 2.95 mm, 3.17 mm and 2.88 mm and thickness 2.13 mm, 2.30 mm and 2.18 mm for Madhuraj, Hanthipanjra and Mahamaya varieties respectively while the geometric mean diameter, surface area and volume were 3.75 mm, 4.33 mm, 3.89 mm and 44.23 mm2, 58.89 mm2, 47.66 mm2 and 28.43 mm3, 43.65 mm3, 31.60 mm3. The aspect ratio and sphericity  were 34.78 %, 28.45 %, 30.77 % and 44.36, 38.82, and 41.47. True density, bulk density and porosity were 1093.98 kg m-3, 1039.86 kg m-3, 1058.48 kg m-3 and 593.56 kg m-3, 527.29 kg m-3, 615.96 kg m-3 and 45.72 %, 49.28 %, 41.69 % respectively. The angle of repose was 32.69°, 29.85°, and 32.98° for Madhuraj, Hanthipanjra and Mahamaya varieties while the static coefficient of friction on glass, plywood and mild steel were 0.45, 0.35, 0.42 and 0.41, 0.38, 0.38 and 0.78, 0.63, 0.64 respectively.
