The oil palm tree first originated in West Africa. Industrial palm oil is red in color and is extracted from the bark of the palm tree, while palm kernel oil is white and is extracted from the inner kernel. The production process of palm oil and palm kernel oil is complex. It contains 45% to 50% oil and is now found all over the world. Depending on the quality of different regions, crude palm oil 20%-22%, palm kernel oil about 2%; Palm oil refining equipment manufacturers briefly introduce the role of palm oil refining complete sets of equipment and the technical process, palm oil in addition to triglycerides other components are called impurities. The role of palm oil refining equipment is to remove the impurities in edible oil, palm oil refining equipment is not to remove all the impurities, but to selectively remove the impurities in the palm hair oil, to maintain the biological properties of the oil and fat, and to retain or extract useful substances.

Composition and nature of impurities in palm oil:

(1)Insoluble solid impurities, such as sludge, cake powder, fiber, clay, catalyst, etc.

(2) Colloidal impurities, such as free fatty acids, sterols, vitamin E, pigments, vitamins, cotton phenol, etc.

(3) Volatile impurities, such as moisture, alcohols, hydrocarbon solvents, odor substances, etc.

Most impurities are harmful to the quality and storage safety of palm oil. For example, moisture not only affects the transparency of the oil, but also promotes hydrolysis and rancidity of the oil; free fatty acids affect the flavor and promote deterioration; phospholipids can make the oil turbid and produce black precipitates when heated. Foaming, bitterness, etc.; a variety of pigments directly affect the color of the oil, but also promote the rancidity of the oil; the presence of colloids, sulfur and phosphorus compounds, saponin and heavy metal salts make it difficult to deacidify the subsequent processes such as steam extraction.

Palm oil refining equipment:

(1) Palm oil degumming: remove phospholipids, mucilage, resin, protein, sugar, trace metals, etc. in crude oil, generally using hydration and acid refining methods.

(2)Palm oil deacidification: remove free fatty acids, acidic pigments, sulfides, insoluble impurities and trace metals from the oil by using food grade lye neutralization method.

(3) Palm oil washing: wash away the saponin and water-soluble impurities remaining in the oil during the deacidification process.

(4) Palm oil dehydration: remove the water in the refined oil by heating and vacuum drying.

(5) Palm oil decolorization: using white clay, aluminum silicate, activated carbon and other adsorbents to remove various pigments, colloids, oxides, etc. in the oil.

(6)Palm oil deodorization: using the principle of vacuum air lifting to remove the low molecular odor substances, free fatty acids, glycerol monoesters, glycolipids, sulfides, and thermal decomposition products of pigments in the oil.

(7) Palm oil dewaxing or degreasing: mainly using freezing, crystallization or winterization crystallization, fractionation to remove waxes and fats from the oil.
