  • 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.
  • How does a screw press work?
  • The screw press has a horizontal main shaft that carries the screw composition which is formed integrally with the shaft. The rotation of the screw occurs inside the cage or barrel that is a structure formed by steel bars. Spacers are placed between the lining bars allowing the drainage of oil as the pressure over the grains is increased.
  • What rpm should a screw press run?
  • Table 2. Oil yields from peanut (Arachis hypogaea L.) Regarding the screw press speeds, a value between 80 and 90 rpm showed the better performance in oil yield and also at this range it was possible to observe an improved performance of the press, producing a cake with a proper consistency and oil with no particulates.
  • 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.
