Vegetable oil refinery in our country is relatively a recent technology inducted in the past two decades. In vegetable oil refining, there are two types of process available viz. chemical refining & physical refining. In chemical refining, there are three main process involves viz. Degumming & Neutralizing, Bleaching & deodorizing for removal of various impurities from the raw oil. So far large quantities of expeller/solvent groundnut oil, rapseed oil are used for edible purpose directly with simple filteration. They are physically purified and they are known as double filtered oils. However, due to more and more awareness about various health aspects, like harmful effects of various natural impurities of raw oils, such as free fatty acid (FFA), the cause for the cholesterol increase, plant pigments, phosphatides etc. consumers prefer refined vegetable oils against simple filtered oils. Oil refining industry has developed considerably in the last one decade. Further more, due to the chronic shortage of vegetable oils in our country, many oils, which are not previously used for human consumption, are being processed and used for human consumption. We have the most integrated automatic and continuous plant from Alfa Laval, Sweden with the capacity of 400 MT per day of edible oil. In processing various oils in our plant, the following technologies are used.
