Mechanical Continuous Oil Expression from Oilseeds: A Review

  • Is mechanical expression a better option than a solvent process?
  • Mechanical expression or mechanical pressing is, however, preferable due to the fact it is economical compared with the solvent process. At the laboratory scale, many authors have highlighted the effect of operating parameters and raw material on process performance (oil yield and press capacity).
  • Does unidirectional hydraulic pressing affect continuous oil expression?
  • Discontinuous hydraulic pressing leads to the similar performance changes as continuous screw pressing. Therefore, the unidirectional hydraulic pressing may be a first approach to evaluate the effect of these pre-treatments on the continuous oil expression.
  • How has oil production changed over the past 20 years?
  • The production of oil from oilseeds is steadily increasing over the past 20 years. For the main oils, 1 there is a production increase of 237 % between 1979 and 1999 (35.4 to 83.0 Mt/year) corresponding to an increase of 12 % per year. While during the last 8 years (1999–2007) the increase has already reached 150 % (83–125 Mt/year).
  • How can phenomenological models of continuous expression be improved?
  • The existing empirical models can be improved by developing phenomenological models of continuous expression based on a better understanding of the physical and chemical phenomena implemented. Taking into account the phenomena of shear in the models would greatly improve the existing models.
