  • How to produce commercial soybean oil?
  • The production of commercial soybean oil is complicated. Below are the main steps of the soybean oil production process. Cleaning Section of Soybean Oil Production: The soybeans are first cleaned, dried and dehulled prior to oil extraction. The soybean hulls needs to be removed because they absorb oil and give a lower yield.
  • What is soybean oil production line?
  • The soybean oil production line is the process of treating soya bean with the press method or leaching method to obtain more crude oil and then refined to obtain edible refined oil. Pressed soybean oil has natural colors, aromas and flavors, and retains raw material’s various nutritious ingredients when comparing with the leached oil.
  • What is pressed soybean oil?
  • Pressed soybean oil hasnatural colors, aromas and flavors, and retains raw material’s various nutritious ingredients when comparing with the leached oil. The physical pressing line requires raw materials to be carefully selected, and the soya bean is pre-treated through cleaning, crushing, softening, rolling and extruding.
  • What are the two methods of soybean oil production?
  • There are two methods of soybean oil production, one is mechanical way, which is a traditional method that use screw press machine to squeeze oil out from seeds and kernels; the other way is chemical method that extract oil with solvents. Both two oil production methods have advantages and disadvantages.
  • How is soybean oil extracted?
  • Magnets are used to separate any iron from the soybeans. The soybeans are also heated to about 75℃ to coagulate the soy proteins to make the oil extraction easier. Extraction Section of Soybean Oil Production: First the soybeans are cut in flakes which are put in a percolation extractors and immerged with a solvent, normally hexane.
  • Is soybean oil extraction environmentally feasible?
  • According to these criteria, the environmental feasibility of these three processes could be obtained and compared. The assessment boundary of soybean oil extraction includes oilseed pretreatment, extracting processes, oil degumming, and coproducts handling. The transportation, however, was not considered (Fig. 2).
