  • How to maximize rapeseed oil yield?
  • In the present study, the optimization aimed to maximize rapeseed oil yield by selecting the suitable screw pressing conditions, i.e., the best nozzle diameter, press head temperature, and screw frequency in the applied experimental domain, by employing the desirability function method.
  • 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 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 factors affect rapeseed oil yield?
  • For a given screw press and seed, the main factors affecting the rapeseed oil yield are nozzle diameter, head press temperature, and screw frequency. Figure 1 shows the nozzle diameter, head press temperature, and screw frequency effects on rapeseed oil yield.
  • 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.
  • What is the oil content of rapeseed seeds?
  • The oil content of the seeds was 40.9?±?0.1%. The rapeseed oil was obtained using an oil screw press (Model SPU 20, Elektromotor-?imon, Senta, Serbia) using various nozzle diameters (8¨C12 mm), temperatures of the press head (40¨C80 °C), and screw frequencies (40¨C60 Hz). A nozzle was set at the exit from the pressing chamber.
