Solvent extraction is achieved through the grinding of seed. The ground seed or cake is then purged or washed with a petroleum distillate (the most commonly used is Hexane) which releases the oil in the seed. The solvent is then flashed off by heating the oil in the sealed chamber. The oil/solvent blend is next heated to distill off the solvent. In our unit, we generally extract rice bran oil. Rice bran is purchased from the market and is received as input our rice Sheller. Rice bran is a by-product of rice Sheller. DOC is a by-product of a solvent plant which is sold in the market.
