Optimum Oil Yield from Egyptian Jatropha Seeds Using Screw Press

Enhancing bio-oil yield extracted from Egyptian castor seeds

  • What is industrial pressing of oilseeds?
  • Industrial pressing of oilseeds is realized using continuous screw presses. The presses are fed with crude or pre-treated seeds. Types of pre-treatments (thermal pre-treatment, size reduction, mechanical sieving, etc.) differ for various seed species (Carr 1997). Each type of seed pre-treatment provides its own advantages.
  • What are hydraulic presses used for?
  • Hydraulic presses are still used for pressing cocoa in order to extract the cocoa butter, in olive oil production, or in specialty oil production. The pressures encountered are very high: above 50 MPa and up to 100 MPa for cocoa and up to 40 MPa for olive oil (De Ginestel 1998; Uzzan 1992).
  • Does hydraulic pressing increase oil yield?
  • The oil yield obtained by hydraulic pressing from the flattened seeds is higher than one obtained from the whole seeds (Khan and Hanna 1984), while for the dehulled seeds, a lower oil yield is obtained by hydraulic pressing (Singh et al. 1984).
  • How much oil does a screw press produce?
  • The results indicate that the maximum oil production is about 40.84% by the screw press which is equivalent to 83.41% by mass fraction of oil in seeds in comparison percentage oil 48.96% in seeds obtained at an engine speed of 20 rpm and preheating temperature of 250 °C.
