  • What kind of machine is used to extract the oil from the sunflower seed?
  • One of the most commonly used method for sunflower oil making is mechanical pressing with screw oil press machine. This methods is relatively simple, features low cost and doesn't require chemical solvents, so it is widely adopted by many medium and small scale cooking oil production line.
  • What is the process of refining sunflower oil?
  • Crude pressed sunflower oil obtained from a local oil mill was refined using chemical method by degumming, neutralization, bleaching and dewaxing.
  • What is the waste from sunflower oil production?
  • Sunflower seed hulls are an abundant waste produced by the edible oil industry. Pyrolysis was assessed as a way of turning this material into a liquid rich in valuable products, as well as leading to densification of this voluminous waste.
  • How is sunflower oil produced?
  • The dehulled sunflower seeds are ground to produce coarse meal. This is then crushed into uniform fine particles using hammer mills or grooved rollers. This fine meal is then heated and then pressed in expellers to obtain oil. The deoiled meal contains some residual oil which is extracted using solvent extraction.
