In cottonseed oil processing, the refining section determines both product safety and final oil grade.
Due to the relatively high content of gossypol and waxes in cottonseed oil, insufficient refining can lead to dark oil color and low-temperature turbidity, limiting its market application.

🍶 With 43 years of expertise in edible oil engineering, QIE GROUP has developed a cottonseed oil refining process that emphasizes both impurity removal and quality upgrading. The complete refining line covers Degumming, Deacidification, Decolorization, Deodorization, and Winterization (dewaxing).

🔹 During degumming and deacidification, hydration degumming and alkali refining effectively remove phospholipids and free fatty acids, while centrifugation simultaneously reduces gossypol content;
🔹 A continuous decolorization system using activated bleaching earth adsorbs pigments and residual impurities, producing a lighter and more stable oil color;
🔹 Under high-vacuum deodorization, off-odors and unstable components are eliminated, improving smoke point and storage stability;
🔹 To address the high wax content of cottonseed oil, a freezing dewaxing (winterization) system ensures oil clarity even under low-temperature conditions.

📈 Only with a well-designed refining process can cottonseed oil truly achieve both safety and premium quality.
