  • What is soybean oil processing equipment?
  • We focus on providing customers with efficient and energy-saving soybean oil processing equipment. The main products include screw oil presses, solvent extraction equipment, refining equipment, etc., covering the complete production chain from soybean pretreatment, oil pressing to oil refining.
  • What solvent is used for soybean oil extraction?
  • The solvent for extraction is usually hexane, and the first stages of extraction can use a mixture of solvent (hexane) and oil, called miscella. Fig. 1 illustrates the conventional setup for the extraction of soybean oil (SBO).
  • 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 .
  • Does ethyl acetate improve the extraction of soybean oil?
  • Dagostin et al. studied the extraction of soybean oil using ethanol as solvent and ethyl acetate as co-solvent; it was discovered an improvement in the extraction for the temperatures of 25 and 40 °C while no improvement in extraction was verified when 5 wt% and 10 wt% of ethyl acetate was added in ethanol at 55 °C.
  • Does extraction of vegetable oil reduce steam consumption?
  • The extraction of vegetable oils is an energy-intensive process. Process improvements for the production of soybean oil were investigated. Energy savings by the individual and combined improvements are calculated, and result in a ∼50% reduction in steam consumption.
  • Can green solvents be used in soybean oil extraction?
  • The application of green solvents in soybean oil extraction is reviewed. Hansen parameters and COSMO-based models can serve as a solvent selection tool. Direct substitution of hexane with green solvents is the most promising alternative. Kinetic models and the thermodynamic assessment are analyzed comprehensively.
