Dewaxing is critical to enhancing edible oil stability as well as preventing crystal formation and cloudiness at low temperatures. Getting the most out of crude sunflower, corn and cottonseed oils requires the right system optimized to your process requirements.
Removing wax from oils improves edible oil transparency at low temperature, which enables effective packing of the oil into transparent bottles. Oil dewaxing systems separate waxes and remove impurities containing wax—safely, reliably and effectively. Comprehensive dewaxing solutions help you cut refining costs, add revenues through oil recovery, and boost your refined edible oil yield.
Sunflower, corn and rice-bran oils contain non-triglyceride compounds-waxes. These waxes impart haziness to the oil at a lower temperature or stored for long periods. Cooling oil to remove high-melting components is known as winterization. Winterizing oils that contain non-triglyceride compounds is frequently called dewaxing. It is an operation designed to preserve limpidity and refined oils brightness. In the winterization process, oil is cooled to de-waxing temperature and proper retention time is provided in the crystallizer to form crystals. Filtration of the oil removes the waxes.
