  • Which vegetable oils are used in hydraulic pressing?
  • In 1942 an article entitled "Expression of vegetable oils" was published where a concern in the scientific study and optimization of the hydraulic pressing of oilseeds was expressed (Koo, 1942). For the study, the author used soybean, cottonseed, canola, peanut, tung nut, sesame seed and castor bean.
  • What are the different methods of vegetable oil extraction?
  • In the first part of this chapter, the commercial methods for the extraction of vegetable oils are reviewed, including: batch hydraulic pressing, solvent extraction and continuous mechanical pressing (also known as screw press). A brief explanation will be given for the new method of producing oil: supercritical extraction.
  • What temperature should a peanut oil press be heated to?
  • As the heating step is costly, it is recommended to heat the grains at lower temperatures, between 40 and 50 oC. The moisture content which favored the press, without contaminating the oil with water, is within the range of peanut commercialization (8 and 12 % wb), thus not requiring any step prior to pressing, such as drying.
  • How to optimize a continuous mechanical press?
  • Optimization of the continuous mechanical pressing consist of defining the optimum parameters, such as temperature and moisture content of grain, or adjustments on the press, in order to reach optimum yields of oil, using a minimum value of pressure applied by the press.
