Palm oil refining degumming and deacidification section

Palm oil refining degumming and deacidification section is the first step in palm oil refining machine.Palm oil refining degumming and deacidification machine palm oil degumming and deacidification machine uses washing method to separate soap residual from mixing oil, providing preparation for next step palm oil refining machine.

Palm Oil Refining Degumming and Deacidification Section Introduction:

Washing: there is still about 500ppm soap in the neutralized oil from the separator. To remove the remaining soap, during palm oil refining degumming and deacidification process add into the oil about 5~8% hot water, with water temperature 3~5 ℃ higher than the oil generally. To achieve more stable washing effect, add phosphoric acid or citric acid when washing. The re-mixed oil and water in the mixer is heated to 90-95℃ by the heater, and then enters the wash separator to separate the remaining soap and most water. The water with soap and oil enters into oil separator to separate out oil in the water. Further catch the oil outside, and the wastewater is discharged to the sewage treatment station.

Vacuum drying stage: there is still moisture in the oil from the wash separator, and the moisture will affect the stability of the oil. So the oil at 90℃ should be sent to vacuum drier to remove the moisture, and then the dehydrated oil goes to the decoloring process of palm oil refining machine . Finally, pump out the dry oil by canned pump.
