  • How to extract soybean oil?
  • Extraction is by successive, countercurrent washes of hexane solvent. The extracted flakes are then carried by a sealed conveyor to be desolventized in enclosed vessels by application of jacket and sparge steam. Hexane is removed from the oil in rising film evaporators and with final vacuum distillation.
  • What is the process of crushing soybeans?
  • Soybean Crushing During the crush process, soybeans are cracked to remove the hull and then rolled into flakes, which are then soaked in a solvent and put through a distilling process to produce pure crude soybean oil. After the oil has been extracted, the soybean flakes are dried, toasted and ground into soybean meal.
  • What is the process of refining soybean oil?
  • Refining the extracted oil Refining involves degumming, Deacidification, decolorization and deodorization process. Deacidification is done by addition of alkaline substance such as sodium carbonate the heated. To remove pigments from the oil white clay is usually used.
  • How is soybean oil made?
  • To produce soybean oil, the soybeans are cracked, adjusted for moisture content, heated to between 60 and 88 (140 and 190), rolled into flakes, and solvent-extracted with hexanes. The oil is then refined, blended for different applications, and sometimes hydrogenated.
