• How is sunflower crushed for oil recovery?
  • Sunflower is crushed for oil recovery via one of two process methods, hard pressing or prepress solvent extraction. Hard pressing relies upon exerting high pressure on the prepared seed to separate oil from the solids fraction, historically recovering about 25% oil from the seed.
  • How hexane is used in sunflower oil extraction?
  • Which is where solvent extraction comes to the rescue. Solvent extraction is the part of the sunflower oil making process in which almost every last drop of oil is extracted from the sunflower seeds. Hexane is the most widely used solvent for this. The process begins with the pouring of hexane over the leftover cake from expeller pressing.
  • Why is prepress solvent extraction better than sunflower meal?
  • Because sunflower oil has a substantially higher economic value than sunflower meal, process economics improve significantly as the oil recovery yield increases. Therefore, prepress solvent extraction, with the highest oil recovery yield, is the process method utilized today for the majority of the sunflower seed that is crushed globally.
  • What are the steps in sunflower oil production?
  • When it comes to sunflower oil, the steps that are critical in the production of clear, high quality, and safe edible oil are degumming, alkali neutralisation, bleaching, dewaxing, deodorisation, and an optional winterization process ¨C each of these processes is explained in detail elsewhere on our blog and website. So there you have it.
  • How does a sunflower extractor recover the solvent pumped to the extractor?
  • The solvent evaporated from the sunflower meal and the miscella are both recovered in the solvent recovery system within the solvent extraction process area. A typical sunflower plant will recover 99.8¨C99.9% of the solvent pumped to the extractor.
  • How is sunflower oil made?
  • But naturally, when carried out at an industrial scale, the sunflower oil making process has more steps and more complexity involved. Within a factory setting, the process begins with preparatory steps and culminates in bleaching and deodorizing ¨C essentially, the refining process. So, how is sunflower oil extracted?
