  • 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 much oil can be extracted from sunflower seeds?
  • The sunflower seed pressing procedure manages to transform about 25–33% of the initial seed weight into oil , while in chemical extraction, the average extracted oil yield is ~42% .
  • How is sunflower seed processed for oil production?
  • Figure 1 shows a flowchart of sunflower seed processing for oil production that results in sunflower seed byproducts (whole and defatted sunflower meals) (Figure 2). The process starts with the crushing of the seed, where the whole sunflower meal is generated.
  • 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.
