How does refining work

The basic working principle of refining equipment is to remove impurities such as protein, mucus, phospholipids, water, pigments, gossypol, etc. from the crude oil through physical or chemical principles, in order to obtain finished oil that meets certain standards. The specific working principle is as follows:

1. Hydration degumming: Utilizing the hydrophilicity of phospholipids and other water-soluble impurities, the water-soluble impurities in crude oil absorb water, expand, condense, and then settle and separate.
2. Acid alkali neutralization: Using alkali to neutralize free fatty acids in oils and fats, the resulting soap adsorbs some other impurities to remove them from the oil.
3. Adsorption decolorization: By using certain substances (such as bleached soil and activated carbon) that have strong selective adsorption effects on pigments, not only can decolorization be achieved, but also trace metal ions and substances that can cause hydrogenation catalyst poisoning can be effectively removed.
4. Distillation deodorization: Utilizing the difference in volatility between the odor substances in fats and triglycerides, the odor substances are removed by steam distillation under high temperature and vacuum conditions.

What is the purpose of a refining machine

Oil refining is the process of removing harmful components from oil according to different purposes and requirements, in order to minimize the loss of neutral oil and beneficial components. At the same time, provide good raw materials for the comprehensive utilization of by-products as much as possible.

What are the application scenarios of refining machines

1. Metal smelting field: Refining machines are widely used in the production process of metal materials such as aluminum, copper, zinc, nickel, etc., which can improve the quality, performance, cost-effectiveness and other indicators of metal products, while reducing the emissions of harmful gases and exhaust gases, achieving environmental protection effects.
2. Chemical production field: In the field of chemical industry, refining machines are widely used in the production process of fine organic chemicals, inorganic acids, anhydrous acids and other materials to improve product purity and quality, and enhance product market competitiveness.
3. In the field of environmental governance: By utilizing technologies such as high-temperature arc, refining machines can treat pollutants and harmful gases into environmentally friendly substances, playing a dual role in pollution control and emission reduction.

What is the production process of a refining machine

The default section of refining equipment includes dephosphorization, degumming, deacidification, decolorization, and deodorization. Some oil products require dewaxing to meet the national standard for first-class oil. The manufacturing process is relatively complex, but the operation is convenient and the performance is stable. Multiple oil crops can easily reach or even exceed the national standard for first-class edible oil.
