  • What is Alfa Laval's role in dewaxing?
  • Alfa Laval provides comprehensive dewaxing solutions that help cut refining costs, add revenues through oil recovery, and boost refined edible oil yield. Dewaxing is a crucial process for enhancing edible oil stability and preventing crystal formation and cloudiness at low temperatures.
  • Why is dewaxing necessary?
  • Dewaxing is necessary to enhance edible oil stability and prevent 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.
  • What are the different types of oil dewaxing methods?
  • Sunflower oil, corn oil, rice bran oil, cottonseed oil and so on. Conventional dewaxing is the common oil dewaxing method with the working principle of freezing and then mechanically separating oil & wax without any auxiliary means, the separating methods are usually pressure filtration, vacuum filtration, and centrifugal separation.
  • Why is Filter Aid powder used in dry dewaxing?
  • Dosing the filter aid powder acts as a control for seeding for crystal growth. Because phosphatides promote crystal growth, bleaching to remove these compounds takes place before the dry dewaxing process. The filter aid powder is a consumable that cannot be reused, and the amount of filter aid is related to amount of wax in feed oil.
  • How does the dry dewaxing process work?
  • The dry dewaxing process involves mixing the oil with filter aid powder and then cooling and maturation. Slow cooling ensures that any crystals formed do not prompt blockage of the filter. Dosing the filter aid powder acts as a control for seeding for crystal growth.
  • What is the difference between oil dewaxing and oil fractionation?
  • During oil dewaxing winterization, oil is kept at low temperature for a period of time and then filtered to remove solid impurities that can cause liquid oil become cloudy. Oil fractionation is a modified process, which involves a larger change in the material components, and improve the physical properties of the oil product.
