Vegetable Oils like Soya, Sunflower, Cottonseeds, Rapeseeds etc. are first subject to the process of degumming. Here phosphotites in the oil are hydrated with water and then removed by separating in the centrifugal separators. The degummed oil is then subject to neutralization with caustic soda where the free fatty acids are converted into soap and are separated in hermetic separators. The neutralized oil is then washed and dried.

The oil is then filtered through pressure leaf filters. The filter leaves used are in special stainless construction with the mesh imported from reputed suppliers.

The filter have special pneumatic vibrators for discharge of cake and special butterfly valve for easy opening and discharge. The bleached oil produced has very low phosphorous levels and no soap.
