Solvent Extraction Plants


solventRice bran is a by-product of the rice milling process. Rice bran is the most important source of edible oil among the unconventional sources. Rice bran is the brown coating around the white starchy rice kernel, which is obtained by dehusking paddy and polishing the rice. While white rice holds little nutritional value, the bran that is removed contains 65 percent of the rice kernel’s nutrients and boasts a bounty of healthful benefits. The thin brown layer that is milled off in the processing of white rice, rice bran is just as effective as the other bran’s in fighting high cholesterol and providing high-grade fiber. India produces about 80 million tonnes of paddy annually. This can yield about 5 million tonnes of rice bran and to the extent of 8 lakhs tonnes of rice bran oil.

Production of rice bran oil is currently estimated at about 2 lakhs tonnes and hardly 10-15 per cent of it is of edible grade, although the potential availability is reckoned at about 8 lakhs tonnes. The wide gap between the actual production and the potential availability of rice bran oil is primarily due to the fact that at present around 70 per cent of the paddy produced in the country is processed through huller mills while only 30 percent is processed by modern sheller mills. It has been estimated that huller mills number about 80,000 while there are only 28,000 modern sheller mills.

Rice bran oil is natural oil that is created using the hull or bran of the rice grain. One of the advantages of using rice bran oil in cooking is that the oil has a high smoking point. This means the oil is ideal for frying foods without running the risk of overheating and burning the food before the meat or coated vegetables are cooked all the way through. The creation of rice bran oil involves the pressing of the hull or bran of the rice grain. By pressing on the hull, small amounts of oil can be extracted and collected. The oil released from the rice bran contains a hefty amount of Vitamin E, gamma oryzanol and the essential fatty acids that lend a great deal of taste to the oil. The presence of a number of antioxidants also help to make rice bran oil a healthier alternative for use in salad dressings and as an ingredient in baked goods. Rice Bran Oil alone has the potentiality of wiping out a large part of the deficit oil in the country
