A Complete Edible Oil Refining Process

Crude oil→Water washing and alkali refining→ Dephosphorization degumming→Continuous decoloration→Continuous deodorization→To fractionation and dewaxing workshop

  • Degumming: To remove the gum impurities, and prepare for the subsequent refining processes.

  • Deacidfying: To remove the free fatty acid in the crude oil.

  • Decoloring: To remove the pigment in the crude oil by adding active bleaching earth, so that can improve the oil quality.

  • Deodorizing: To remove the odor in the oil, so that can improve the flavor, stability, color and quality of the oil.
