  • What is solvent extraction of soybean oil?
  • The solvent extraction of soybean oil has become the most popular extraction method used across the globe. With a distinct advantage over traditional mechanical pressing, solvent extraction yields higher oil recovery and greater efficiency, leaving less than 1% residual oil in the meal.
  • Which method of oil removal is used in soybean processing?
  • Mechanical pressing and solvent extraction are the two primary methods of oil removal used in soybean processing. The mechanical process, with hydraulic pressing and continuous screw pressing techniques, was used before the development of solvent extraction [ 9 ].
  • How is soybean oil extracted?
  • Yet, some operators overlook a critical step in their soybean oil extraction process to save significant time and energy. In solvent extraction, flaked soybeans are washed with hot solvent, typically hexane, to separate the solids from the fats. Multiple washes dissolve the oil and carry it away.
  • Can two-stage extruding-expelling process improve soybean oil yield?
  • To examine the viability of this improved two-stage extruding-expelling process, techno-economic analysis was performed by using SuperPro Designer for simulation of the soybean extruding-expelling process. Soybean oil yield increases to over 70% compared to the conventional single-step expelling process with 60%.
