Why do the edible oil need be refined?

Why do the edible oil need to berefined? Of course it is because the crude oil contains some useless or unhealthy impurities, which can not only makes the storage time shorter, but also makes the flavor worse. And the edible oil refining project has huge profit margins, please see my analysis below.

With the improvement of commodity quality standards in the edible oil market, edible oil refining projects have gradually entered people's field of vision. Although some crude pressed oil or extracted crude oil is edible, it still can not meet the national food safety standards. The presence of impurities in crude oil not only affects the edible value and safe storage of the fat, but also brings difficulties to deep processing. Therefore, if you want to produce higher-quality edible oil products for higher-level edible oil market, it is inevitable to learn about the edible oil refining projects, even need to know the knowledge of edible oil packaging. Therefore, in recent years, they have been popular among edible oil manufacturers. Including the favor of small oil mills. Below I will give you a detailed introduction to the equipment and processing steps used in the edible oil refining section.

Through edible oil refining process, we can change the crude oil into the refined oil. And the reining process mainly include four steps: degumming, deacidification, decolorization and deodorization.

Edible oil refining process flow chart

1 Deacidification step removes excessive free fatty acids in crude oil. This is the most important step in the entire refining process. Alkali refining method uses alkali to neutralize free fatty acids, so that free fatty acids produce soap feet and can be separated and there will be a healthier edible oil.
2 Decolorization step adopts the adsorption decolorization method to remove the pigment in the crude oil to make the oil looks better.
3 Deodorization can not only remove the odorous substances in the crude oil, increase the smoke point in the fat but also can improve the flavor of the oil effectively.
4 Deodorization of crude oil is to pass water vapor into the crude oil tank in a high vacuum state, and use the steam to remove high-temperature oil stains and peculiar smells to achieve the purpose of deodorization.

The above is the whole content of the edible oil refining process. The edible oil refining equipment produced by our professional engineer team can help you obtain quality refined oil.
