Vegetable Oil Refinery

Oil refinery plant refers to a series of refining processes that can remove phospholipids, FFA, pigment, off-flavor and other impurities in the oil. Edible oil refinery or vegetable oil refinery  is essential to ensure removal of gums, waxes, phosphatides and free fatty acid (F. F.A.) from the oil. To impart uniform colur by removal of coloring pigments and to get rid of unpleasant smell from the oil by removal of odiferous matter.

Oil Refinery Plant

Oil refinery plant usually includes the following sections: Degumming, Neutralization, Bleaching, Dewaxing and Deodorization. The process of removing these impurities after oil extraction section is called oil refining. The crude oil obtained either from expellers or solvent extraction plant contains impurities, which must be removed to make the oil edible, more palatable and stable against rancidity upon storage.

Refining Methods for Vegetable Oil Refinery

There are two refining methods for the vegetable oil refinery in the ebtire oil refinery plant.They are physical refining and chemical refining. Physical refining means removing gum in oil during process of degumming in special method and removing FFA in process of deodorizing by steam. Chemical refining, however, means removing FFA in a chemical way ( Acid-base neutralization). Gum and soap foot produced is separated by centrifuges.

Oil Refinery Plant

Vegetable Oil Refinery - Chemical Refining

  • The finished oil is consistent and stable.
  • Excellent adaptability and less requirement to oil quality.
  • Less bleaching earth is added into compared with physical refining.

Vegetable Oil Refinery - Physical Refining

  • High oil refining rate, less oil loss.
  • No waste water discharged.
  • Especially suitable for oils of high acid value, and low gum content.
  • More FFA distilled out.
