Cooking oil refining machine

Cooking oil refining machine can be used to remove harmful impurities in the oil for edible, storage and industrial production. For example, phospholipids, protein, mucus, gossypol, moisture should be removed, and beneficial impurities such as tocopherol will be held.

Cooking Oil refining process:

Crude cooking oil—degumming—deacidification—decolorization—deodorization—(winterization/fractionation)—standard edible oil

A. Degumming

Oil widely use water degumming and acid degumming.

a. Water Degumming: Hydratable gums are removed by treating oils with water and separating the gums. The gums can be dried to produce lecithin.

b. Acid Degumming: Non-Hydratable gums are removed by treating oils with acids and separating the gums.

Adding a certain amount of hot water or dilute alkali, salt, phosphoric acid these electrolyte solution into hot crude oil under stripping, it makes the gum soluble impurities absorption and condensation, and then settlement separate.

B. deacidification

The purpose of deacidification is to remove Free-Fatty Acids (FFAs) in crude oi. Traditionally, use Alkali to remove acid, and carry out neutralization of chemical reaction to reach deacidification. The reaction produces Soaps which are separated from the oil.

C. decolorization

After degumming and deacidification, we can get grade 3 or grade 4 oil, but if we want top grade oil(salad oil, cosmetic oil, oil for light colored paint, soap and margarine) ,we need to remove some pigment inside oil. The most widely way is absorption method that is using white clay to absorb pigment out of the oil.

D. Deodorization

Natural oil has its own special smell (odor), and in the process of oil production will also produce odor (such as solvent smell, soap taste and earthy etc). Deodorization means a process to remove the special smell of oil. The best method for deodorization is vacuum steam deodorization. Our machine for deodorization is deodorization tower. It uses superheated steam (vacuum) to remove flavor substances in the oil.

E.Winterizing/Dewaxing

The purpose of Winterization is to remove waxes especially in those oils that contain waxes. Such oils are subjected to chilling and filtration to remove waxes and other high melting point substances.
