Soya Physical Refining:-

Conveyor Systems

The Soya Physical Refining or Soya steam refining process has the advantage of eliminating the caustic refining and soapstock acidulation process. The pree fatth acid content of crude soyabean oil can easily be removed in a steam refining deodorizer, however any phosphates present in the feedstock will char at the high temperature used for steam refining deodorizing. Its claimed that a crude soyabean oil suitable for steam refining deodorizing can be prepared by water degumming followed by phosphoric acid treatment
