The groundnut oil refining process in small groundnut oil refinery plant has four stages: degumming, deacidification(neutralization), decolorization(bleaching) and deodorization.
Degumming: To remove the content of colloidal impurities in the oil. Usually add P-acid or hot water to make the colloidal impurities sink and is separated out.
Neutralization: To reduce the level of free fatty acid (FFA) in the oil, caustic soda is mixed with the crude oil and the mixture is fed to a hydration tank. The neutralized oil may have trace of soap which is a by-product of the neutralization process. Therefore, the oil will be washed with water.
Bleaching: The neutralized oil is then pumped to the bleacher in which it is mixed with bleaching earth to improve the color of oil by the process called adsorption. At this stage, any undesirable impurities from the crude Groundnut oil are removed. This process improves the initial taste, final flavour and oxidative stability of the product. The bleached oil is then filtered to remove the bleaching earth leaving the oil with very low phosphorous levels and no soap.
Deodorization: The bleached oil, after being filtered, will be pumped to the deodorizer to avoid substances which are responsible for the odor of edible oil.
