Oil refining is usually refined on the crude oil, the presence of impurities in the oil, not only affect the value of oil and safe storage, but also difficult to deep-processing, but refining, not all the impurities in the oil are removed Such as gossypol, protein, phospholipids, mucus, water, etc., and beneficial impurities, such as tocopherol, sterols and so on, should be retained in order to avoid the loss of impurities in the food, storage, industrial production and other harmful. Therefore, according to different requirements and uses, will be unwanted and harmful impurities from the grease out to be consistent with certain standards of refined oil, is the purpose of oil refining.

Process:

1. Degumming Section: Some impurity, such as Phospholipid, gum, and protein, can be oil when there is no water, but once there is water in oil, these impurities can be dissolved into water. So, in the degumming section, we use the hot water to wash crude oil.
2. Neutralizing Section: Crude oil contains much free fatty acid, which is harmful to health. Free fatty acid can have the reaction with caustic soda, during the reaction, it can be saponified and becomes soapstock Then small soapstock pellets will sink and becomes sediment and be pumped out. After neutralizing most of the free fatty acid will be removed out.
3. Decolorization Section: Most of the crude oil has deep color because of the pigments, such as carotene, xanthophyll, etc. We use bleaching earth to remove pigments because bleaching earth has strong adsorption capacity. Then pump oil into plate filter to remove bleaching earth then pigment also will be removed out along with bleaching earth, then oil will be clean and transparent.
4. Deodorizing Section: Pure oil has no smell, but different crude oil has their special smell because of some volatile matters, for example, the oxide for ketones, aldehydes, hydrocarbons. In the deodorizing section, we deliver steam into oil continuously and make sure steam and oil fully contacted under high temperature and pressure, then volatile matters can be removed out along with the steam.

Main Features

1.The small refined oil equipment adopts food grade stainless steel material and is polished to meet the food machinery standards.

2. Simple design, refined appearance, improve customer satisfaction.
3. The operation data is all displayed by the instrument, the operation is simple, and the operation is safe; .
4. Small refined oil equipment can achieve the dephosphorization, de-alkali, dehydration function of the oil, according to the needs of users can also perform constant temperature decolorization.
