Abstract :
Some physical properties of paddy rice are necessary for the drying, parboiling, storage structures, storage, and processing equipment and for the design of handling, transportation and processing operations. The physical properties length (L), width (W), thickness (T) of four Egyptian varieties paddy rice were determined at a moisture content of 14% ±0.24 % (wet basis) namely Egyptian jasmine, Sakha 106, Giza 179 and Hybrid1 rice. Some physical properties for paddy are discussed briefly. The average grain length, width and thickness were measured. The surface area and the volume were determined. The values of particle density, bulk density, and porosity were measured. The equivalent diameter and the weight of 1000 grains were also measured. The kernels sphericity was calculated. The Aspect ratio which is used as an indicator of a tendency toward an oblong shape was founded.
