  • What is oilseed rape?
  • Oilseed rape is the most significant member of Brassicaceae family in terms of economic value. Its oil is the third largest source of vegetable oil in world (USDA, 2016) after palm and soybean oil. This industrial crop is cultivated for high quality oil used in human nutrition, as well as for biodiesel production.
  • How screw press conditions affect rapeseed oil yield?
  • The operating screw pressing conditions can significantly affect the oil yield from rapeseed. For a given screw press and seed, the main factors affecting the rapeseed oil yield are nozzle diameter, head press temperature, and screw frequency.
  • Is rapeseed a good vegetable oil?
  • Rapeseed (Brassica napus L.) is the world's second produced oilseed and accounts for nearly 12% of world major vegetable oil production. For the last 10 years, the production, planting area, and yield of rapeseed have been stable, with improvement of seed quality and especially seed oil content.
  • How much rapeseed oil can be extracted by cold pressing?
  • A nozzle diameter of 10 mm, a screw frequency of 50 Hz, and a press head temperature of 80 °C ensured the maximum pressed rapeseed oil yield of 26.65% within the applied experimental domain. The crude oil extraction degree achieved by cold pressing was 60.8% of the rapeseed oil yield obtained by the Soxhlet method.
