  • What are the benefits of solvent extraction?
  • As lateral benefit, the residual oil in hulls is also improved, bringing down the oil in hull from almost 2% to 1% (for soybean). In addition, the evolution of technologies in solvent extraction have made it possible to dramatically reduce hexane residual contents in the oil, in the meal and in the air (Tab. 2).
  • 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.
  • 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).
  • 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 the residual oil content of soybean meal?
  • It is critical to avoid the presence of cracks in order to get reasonable residual oil content in the meal. In a modern and efficient extraction plant (Fig. 9), a residual oil content ¡Ü?0.5% for soybean meal is expected.
  • How is crude oil produced in a soybean crushing plant?
  • The crude oil is usually water degummed in the crushing plant which generates an additional flow, consisting of gums (or lecithin). Table 1 presents the main quality parameters (optimal contents) of the major products from soybean crushing.
