• How does a soybean oil extraction process work?
  • The extraction process uses hexane or other solvents to wash the soybean oil from the prepared soybean flakes. The design of the equipment varies so that Crown can optimize the amount of solvent and bed depth needed to efficiently wash the flakes, the contact time of the solvent and flakes, and the power and utilities needed to run the equipment.
  • What solvent is used to make soybean protein concentrate?
  • It should be noted that other solvents may be required to produce different and specific products; for example, an alcohol-water mixture is used in an additional extraction step (after hexane extraction) to produce soy protein concentrate (or ¡°SPC¡±) by removing the sugars from standard soybean meal (Wang et al., 2004).
  • How is soybean oil extracted from soybean flakes?
  • Finally, mechanical rollers are used to make thin flakes and rupture the cells containing the soybean oil. The extraction process uses hexane or other solvents to wash the soybean oil from the prepared soybean flakes.
  • What is a good residual oil content for a hexane extractor?
  • A minimal residual oil content in the meal coming out of the hexane extractor is a clear benefit for a crushing plant; the more oil yield the better revenue for the crusher. In a modern and efficient extraction plant, a residual oil content ¡Ü?0.5% for soybean meal is expected.
  • What is desolventized soybean oil?
  • For the soybean oil, a distillation system is used to recover the solvent. The desolventized flakes are now a product and ready for sale as a good source of protein. The soybean oil can be further refined from a crude product to an edible product. Extracted and desolventized soy oil must be further processed to make an edible product.
  • What is solvent extraction?
  • Solvent extraction consists in washing the prepared material in a countercurrent multistage process to enable a reasonable quantity of solvent to extract a maximal amount of oil. Major progresses in solvent extraction relate to plant production capacity increases which propelled technological improvements.
