  • What are the three methods used for vegetable oil production?
  • Commercially, there are three methods used for the production of vegetable oils: batch hydraulic pressing, continuous mechanical pressing and solvent extraction. Each of these technologies will be detailed below The first step of the process, common to all technologies, is the preparation of raw material.
  • How were oilseeds processed?
  • In the late nineteenth century, oilseeds were processed in manual presses, where layers of grains were placed into the equipment, separated by filter cloths and filter press plates and force was applied via a hydraulic cylinder.
  • 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.
  • Which applications require a hydraulic press?
  • With the emergence of the continuous screw-press, the only application that still requires the hydraulic press is the one that requires gentle handling, such as processing and production of cocoa butter. Presses from this category can be divided into two main groups: open and closed type (Williams, 2005).
