Vegetable oil and fat resources are indispensable to mankind as a source of nutrient and industrial raw materials. Crude vegetable oil obtained from various oil milling units is further refined before use for edible purposes. Refined edible oil is a process where free fatty acids are volatized, condensed and recovered simultaneously with vacuum de-colouring operation.
Sometimes,
refining process is limited to simple physical treatment such as heating and filtering in regard to refining of superior quality of crude oil. Generally the cake in the oil is separated by centrifuge, decolouring by active clay and steam deodorization at high temperature in vacuum up to 5 mm. Hg. This is not a location specific project and can be set up at a place where crude oil is easily available. The preferred locations can be Gujarat, AP, Maharashtra and so on.
