Physical Deodorizing Section
SPECTECs new generation Physical Refinery Plants are ideal solution for minimizing processing cost & processing loss.
For high FFA oils such as Palm Oil & Rice Bran Oil this process is most common
Crude oil from obtained from expellers, solvent extraction plant contains foreign impurities such as mucilage, gums and unfiltered protein us matter from the seed. It also contains gums & Free Fatty Acids which making it unfit for edible purpose.
Batch refining consists of following sections.
1) Degumming
2) Bleaching
3) De-waxing
4) Physical deodorizing
Therefore the first stage of refining is to separate these gums & foreign impurities with chemicals and hot water treatment called as degumming process. Thereafter the degummed oil is further processed in bleaching section under vacuum and treated with bleaching earth and carbon for reduction of color pigments. Next it will be deodorization, where unwanted Free Fatty Acids & color pigments are removed at high temperature in the presence of high vacuum.The edible oil obtained from refinery is of good quality meeting all requirements of international standards.
