• What are the advantages of Physical refining of sunflower oil?
  • Physical refining has several advantages compared to the classical chemical one. This process is more economical (improved yield, lower investment cost, less chemicals used) environmental friendly process (no soapstock to be treated, splitted) but more sensitive to the crude oil quality. Physical refining of sunflower oil is discussed in details.
  • How is crude pressed sunflower oil refined?
  • Crude pressed sunflower oil obtained from a local oil mill was refined using chemical method by degumming, neutralization, bleaching and dewaxing. The quality and composition of crude and refined oil were compared. The phosphorous content, FFA content, peroxide value and wax content decreased during the refining process.
  • How to refine sunflower oil?
  • Physical refining of sunflower oil is discussed in details. Recent developments in the field of processes, equipment and control have made possible to refine by physical way the high phosphatide containing seed oils as well.
  • What is a sunflower oil refining unit?
  • An experimental oil refining unit has been developed for minimal refining of sunflower oil. The unit consists of (i) one open mild steel tank with conical bottom for degumming/neutralization, (ii) one closed oval tank for vacuum drying/bleaching and (iii) one filter for filtration of oil.
  • What is a large capacity sunflower oil refining line?
  • Huge capacity sunflower oil physical refining lines are successfully operating in different countries using the developments of last decades resulting in better processes, more suitable adsorbent, high capacity equipment with really improved performance producing high quality refined sunflower oil in a more economic and environmental friendly way.
  • Does crude sunflower oil oxidize?
  • As the crude sunflower oil contains – as a minor component – natural antioxidant (tocopherol 700- 1,000 mg/kg) usually there is no autooxidation problem except in the case of extreme non-proper storage – transport conditions. Degumming processes
