  • What is the future of soybean production in Africa?
  • Soybean production is expected to dominate in the future in Africa due to its cash crop value from oil extraction and animal feed. Governmental and agro©industries can help provide the required economic opportunities through improved soybean©based supply chains involving consumers and producers.
  • 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 to extract soybean oil?
  • Soybean oil can be obtained by expelling or using an organic solvent. Although, the employment of solvent will always follow the expelling to increase lipid extraction yield .
  • Which solvent is used in soybean oil production?
  • Solvent extraction and expelling are the main processes used in soybean oil production. Hexane is currently the leading solvent in extraction , . This solvent has a high solubility for oil extraction, availability, low price, low boiling point, and heat of vaporization .
  • What are the three stages of soybean oil production?
  • Soybean oil production includes three main stages: preprocessing, extraction and separation, and post-processing. The preprocessing of the raw soybean includes drying, storage, mechanical cleaning, dehulling, and flaking.
  • Is ethanol better than hexane for soybean oil extraction?
  • Despite the fact that soybean oil extraction with hexane is more efficient, in terms of a more concentrated miscella, the outcomes obtained in this study revealed that is possible to exhaust the raw material with ethanol, and that a high oil recovery value can be reached when a S / F = 3/1 is employed.
