Why crude oil needs refining and the essential equipment for the process?

Crude cooking oil needs refining because in its unrefined state, it contains impurities such as free fatty acids, phospholipids, pigments, and odors that can affect the quality, flavor, and shelf life of the final product. However, for the consumers, refining can bring high quality and safe cooking oil, which is very important for the health. Besides, the crude oil refining process not only enhances the taste and appearance of the oil but also improves its stability, making it suitable for cooking, frying, and food production.

Then what essential equipment is there in crude oil refining process?

1. The degumming equipment is one of the first steps in crude oil refining process. It is used to remove phospholipids and other gum-like substances that can cause cloudiness and affect the oil’s quality.

2. This is followed by the neutralization equipment, where free fatty acids are neutralized to reduce acidity, ensuring a milder taste and improved quality.

3. Next, the crude oil undergoes bleaching process, a step in which pigments and other coloring substances are removed using a bleaching equipment. This equipment helps achieve a clearer, more visually appealing oil.

4. The final stage in refining involves deodorization, where the oil is heated under vacuum conditions in a deodorizing tower to eliminate unpleasant odors and flavors, resulting in a neutral, fresh-tasting oil.
