Palm oil is an important vegetable oil, which is widely used in food, cosmetics, industry and other fields. However, untreated palm oil usually contains impurities and bad smell, so it cannot be used directly, so it needs to be refined to improve its quality. Palm oil refining equipment plays a key role in this process, and the types of equipment are different according to different refining processes. The following are the main types and characteristics of palm oil refining equipment.

1. Degumming equipment

Degumming is the first step of palm oil refining, which is mainly used to remove phospholipids and colloidal substances in oil. Common degumming equipment includes mixing tank and settling tank. The mixing tank is used to mix acid or water with crude oil to coagulate colloidal substances; The settling tank is used to separate the condensed impurities. Some refineries will also use centrifuges for more efficient separation.

2. Deacidification equipment

Deacidification process is mainly to remove free fatty acids from palm oil to reduce acid value and improve oil quality. Deacidification equipment is usually treated by chemical method or physical method. Chemical method uses neutralization reaction, and forms soap feet by adding alkaline substances (such as sodium hydroxide) and fatty acids, while physical law directly removes fatty acids by distillation or degassing technology.

3. Decolorization equipment

In the process of palm oil refining, decoloration is to remove pigments and other impurities in crude oil, so that the oil product presents a clearer appearance. Decolorization equipment usually includes a decoloring tank and a filter. Adsorbent (such as activated clay or activated carbon) is added into the decoloring tank to remove pigment through adsorption; The filter is used to separate adsorbent from refined palm oil.

4. Deodorization equipment

The bad smell in palm oil mainly comes from volatile components, which need to be removed by deodorization process. Deodorization equipment generally adopts vacuum distillation technology to evaporate volatile substances through high temperature and low pressure environment, so as to achieve the purpose of removing odor. This step not only improves the smell of oil, but also extends its shelf life.

5. Cooling and storage equipment

After completing the above refining steps, palm oil needs to be cooled and stored to ensure its stable quality. The cooling equipment is usually a heat exchanger or a cooling tank, and the storage tank is used to store refined oil to ensure its hygiene and safety. In a word, there are many kinds of palm oil refining equipment, which complement each other in the whole process and jointly complete the transformation from crude oil to refined oil. With the continuous progress of technology, modern refining equipment is developing in a more efficient and environmentally friendly direction, which provides strong support for palm oil industry.
