FAQ

  • 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.
  • 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.
  • What is the mass flow rate of pressed rapeseed oil?
  • The temperature of the pressed oil at the exit from the press was 40 °C. The mass flow rate of the press cake and pressed rapeseed oil under these pressing conditions were 174 ± 22 g/min and 52.7 ± 0.1 g/min, respectively. Optimization of screw-pressing process factors can involve the oil recovery yield or quality properties.
  • How rapeseed oil is extracted by cold pressing compared to Soxhlet Method?
  • The crude oil extraction degree achieved by cold pressing was 60.8% compared to the Soxhlet method. The rapeseed oil contains predominantly oleic, linoleic, linolenic, and palmitic acids, agreeing with other reported rapeseed oils.
  • Does soaking time affect rapeseed oleosome extraction?
  • Rapeseed water absorption reaches a plateau at 8 h. Water diffusion is negatively associated to the mechanical strength of the seeds. The mechanical properties of rapeseeds after 8 h soaking time are ideal for oleosome extraction. The extraction yields are not affected by the soaking time when using a twin-screw press.
