What impurities are removed through oil refining equipment?
The oil that is just crushed by the oil squeezing equipment is called crude oil or crude oil. It contains a lot of impurities and needs to be treated with refining equipment to remove the impurities inside. What impurities can oil refinery equipment be removed? Let's analyze it in detail.
Most of the composition of coarse oil is mixed fatty acid triglyceride, which is neutral oil, which we call it pure oil. In addition, there are many non -glycerin components, which are what we call impurities. The protagonist we want to talk about here is these impurities. Let's take a look at what impurities are:

1. Solid impurities. It consists of sediment, embryo, cake residue, fiber, wood chips, dust and other solid impurities. This type of impurities insoluble in oil and impurities in oil.
2. Water impurities. Water is also a common impurities in oils, with two sources. One is the water remaining in the oil during oil, and the other is the water actively added during hydration and dehydration. Refined equipment can remove water in oil and fat. These moisture will change the color of the fat, produce odor, and accelerate acid failure.
3. Collagen impurities. Such impurities are mainly phospholipids, protein, sugar, resin, and mucus. They are easily affected by water temperature and electrolytes and change the state in oil. This refined equipment remove insoluble impurities through hydration, dehydration and other methods.

4. Lipid -soluble impurities. The main components of this type of impurities are free fatty acids, pigments, alcohols, macarol, hydrocarbons, wax, ketones, trace metals and organic phosphorus, mercury, polygon gallery, mold, and other gallel toxin caused by environmental pollution. These impurities can be removed through alkaline melting and use of refined equipment.
5. Trace impurities. Metals, pesticides, polychic aromatics, yellow cytoids, etc., will be removed in all links during the refining process of this type of impurities. For example, alkaline refined links can remove yellow glimotoxin, and metal impurities can be removed.
