  • How does pressure affect yields of Sesame & Jatropha?
  • Yields for sesame and jatropha for linear increase in pressure at different speeds (Pend = 30 MPa, T = 40°C, time of pressing: 10 min, 10 g of dry seeds). 4.2.3. Influence of temperature Experiments were performed for all seeds at temperatures of 40, 80 and 100 °C and a constant mechanical pressure of 30 MPa.
  • How does temperature affect the yield of sesame & linseed oil?
  • Yield increased with increase in pressure and with increase in temperature. For both sesame and linseed maximum oil yield was obtained at a moisture content of about 4 wt%.
  • What is the maximum oil yield for linseed & sesame seeds?
  • For both sesame and linseed maximum oil yield was obtained at a moisture content of about 4 wt%. Maximum yields obtained were 45–55 wt% (oil/oil) for hulled seeds (linseed, rapeseed, palm kernel and jatropha) and 70–75 wt% (oil/oil) for dehulled seeds (sesame and dehulled jatropha).
  • What are the regression coefficients for linseed & sesame seeds?
  • Regression coefficients for all oils were 0.997 or better. The μ1 -values obtained for sesame seed and rapeseed are similar (25.8 and 26.0 kJ/mol), whereas for linseed it is lower (23.0 kJ/mol).
  • Which mathematical models are used in oilseed expression?
  • Mathematical models previously used in oilseed expression are either empirical (Fasina and Ajibola 1990), based on the nature of cell structures (Lanoisellé et al., 1996)) or Terzagi type models (Mrema and McNulty, 1985, Shirato et al., 1986). The first type is limited to specific seeds and equipment on which the measurements were done.
  • How to recover oil from seeds?
  • For most of this time, the only option to recover the oil from the seeds has been mechanical expression (pressing). The oil obtained via this method is of a high quality, but the attainable yield is limited to roughly 80 wt% of the oil originally present (Hasenhuettl, 1991).
