Interaction of physical and milling characteristics of paddy

Milling characteristics of eighteen varieties of paddy grown in India were determined along with their physical characteristics, namely length, width and thickness of brown rice and milled rice. Statistical analysis was condu cted to correlate the physical dimensions with milling characteristics. Fis sure contents were also measured and mathematical models were developed to predict the broken content of milled rice. The brown rice yield varied from 75.1% to 79.60%. whereas the milling yield ranged from 67.01% to 75.45% at a constant time of polishing.
