  • How is soybean oil extracted in a continuous and countercurrent process?
  • Extraction of soybean oil in a continuous and countercurrent process. Multistage extraction was experimentally reproduced from batch single-stage assays. The process efficiency was mainly limited by the oil solubility in the solvent. The minimum solvent mass flow and the number of ideal stages were calculated.
  • How is oil extracted from soybeans?
  • Due to the moderate oil content (18 ¨C 23%mass) , it is mandatorily recovered from soybeans by solvent extraction . Currently, industries adopt a continuous-countercurrent-multistage extractor for oil extraction from vegetable oilseeds.
  • Can ethanol be used as a solvent for soybean oil extraction?
  • It was possible to use single-batch experimental assays in laboratorial-scale to evaluate key parameters for soybean oil extraction using ethanol as solvent. Such parameters may assist the design and development of continuous and countercurrent extractors adopting fixed bed columns in series as contact stages.
  • 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).
  • Can a continuous bed extractor extract soybean oil with anhydrous ethanol?
  • Here, a continuous extractor composed of fixed bed columns connected in series (resembling the so-called simulated moving bed extractor) for soybean oil extraction with anhydrous ethanol was experimentally reproduced by a multiple-batch solid-liquid extraction system.
  • How is oil extracted from soy flakes?
  • During solvent extraction oil is removed from the soy flakes by an organic solvent to form an oil/solvent mixture called a miscella. The oil is recovered from the miscella by removing the solvent by steam stripping. Most commercial oil extraction is currently by hexane extraction, but other solvents have been considered.
