"UMAS" Oil Refining Plants




Refining is a process used for removal of undesirable elements like free fatty acids (FFA), gums, phosphatides etc. from oil and to improve its quality and ensure colour uniformity. The process involves degumming, neutralising, bleaching and deodorisation.

Batch Oil Refining Process
For small capacity plants below 20-25 tons per day, batch process is recommended being low cost and easy to operate thus making the plant economically viable.

Continuous Oil Refining Process
We recommend Continuous Oil Refining process for 25 tons and above capacity Plants. Two processes have been developed for Continuous refining of edible oils i.e. chemical refining and physical refining.

Chemical Refining :
This is the traditional method where the free fatty acids of the crude oils are neutralised with caustic soda. The resultant sodium soaps are separated by means of Separators. The neutral oils are subsequently bleached and deodorised. This method can be used for reliably refining virtually all crude oils.
Continuous Oil Refining Process

Physical Refining :
In this method the free fatty acids are removed by distillation in one stage during deodorisation. A fundamental criterion for using this method is that the crude oils should be degummed as effectively as possible. However, this is only possible to a limited extent with some crude oil qualities.

UMAS can supply suitable process lines for both the processes.
