  • Can we extract oil from grape seeds by cold screw pressing?
  • This study evaluated the physical properties and oil extraction from grape seeds from three white (Welschriesling, Green Veltliner, Hibernal) and two red (Zweigelt and Saint Laurent) must varieties of grapevine by cold screw pressing as the appropriate extraction process.
  • How much oil is pressed from grape seeds?
  • The quantity of the pressed oil ranges from 67.5 to 98.5 g.kg⁻¹ and thus depends on the variety. The measured results can be used in commercial practice for optimizing the pressing process for pressing of oil from grape seeds. Effect of the number of revolutions of the press spindle for oil yield (%) in seeds of white grape varieties.
  • Which seeds produce high value added oil?
  • For this study, sesame, linseed, palm kernel and jatropha were chosen, because these seeds represent a wide range of physical properties and produce high value added oils. They range from soft to hard and from high to relatively low oil content. Furthermore rapeseed was included as a representative of the bulk oilseeds.
  • How much oil can a kilo seed produce?
  • The results have confirmed that when the screw rotation speed is changed from 20 to 80 rpm, the press capacity increases on average from 0.84 kg.h⁻¹ to 1.75 kg.h⁻¹, but simultaneously the oil yield reduces from 9.85 to 6.75%. This means that one kilogram of seed may produce 67.5 to 98.5 g of oil.
