Flow-Sheet
For The Sharpless Low Loss Continuous Vegetable Oil Refining
Process
Continuous Neutralising
Process is carried through high speed centrifuge.
There are various operations like De-gumming, Alkali
Treatment, Water washing and Oil drying in this
process.
In continuous neutralisation process metered quantity
of weak solution of the Phosphoric acid is mixed
with crude oil in mixer and the resultant Gums are
separated by high speed centrifuge. In the next
process, the De-gummed oil / crude oil is treated
with metered quantity of Caustic Soda (NaOH) and
soap stock is separated continuously by centrifuge.
In the final process, Neutralised oil is washed
with the hot water to remove soap particle and also
free alkali particle by centrifuge and clear Neutralised
oil is obtained continuously.
This oil is further dried in vacuum dryer to remove
excess moisture.
The oil obtained from centrifuge is light coloured,
free from soap stock and called as washed Neutralised
oil.
