Rapeseed Oil Pretreatment Machine with Rapeseed Oil

  • 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 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 is rapeseed oil obtained?
  • Rapeseed oil was obtained by cold pressing in a laboratory hydraulic press (Sirio, Mikodental, 10-ton strength, 40 MPa maximum pressure) at room temperature. The procedure was done in triplicate. Upon pressing, oil samples were immediately analyzed.
  • 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-Šimon, Senta, Serbia) using various nozzle diameters (8–12 mm), temperatures of the press head (40–80 °C), and screw frequencies (40–60 Hz). A nozzle was set at the exit from the pressing chamber.
