Schematic diagram of oil extraction by screw

  • What are the optimum conditions for oil extraction by screw press?
  • The results indicate that the optimum conditions oil extraction by screw press were 200 °C extraction temperature and 60 rpm screw speed. It could be seen that the extraction oil yield, extraction energy requirements and extraction time were 35.59%, 18.68 and 1.86 min, respectively.
  • 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.
  • Does a screw press affect oil yield?
  • In these experiments, the performance of the screw press (oil yield) followed a second order decreasing polynomial function of seed moisture content (Singh et al. 2002). The moisture content of seeds during the pressing process also affects the quality of oil.
  • Does extraction screw speed affect oil extraction yield from castor seeds?
  • To achieve that, the effects of extraction screw speed (30, 60 and 90 rpm) and temperature (120, 140, 160 and 200 °C) on oil extraction yield from castor seeds, extraction energy and extraction time were studied. The results indicate that, the highest value of decreasing of oil extraction yield
