• What is rapeseed pressing & processing?
  • Rapeseed (Canola) Pressing/Processing, Sunflower Pressing/Processing – 200 Tons of Seeds Per Day. A perfect combination of mechanical and thermal processing. It employs the benefits of extrusion for the subsequent pressing step (increasing oil yield). One-level pressing with extrusion is a technology specially developed for processing soybeans.
  • What is the mass flow rate of pressed rapeseed oil?
  • The temperature of the pressed oil at the exit from the press was 40 ¡ãC. The mass flow rate of the press cake and pressed rapeseed oil under these pressing conditions were 174?¡À?22 g/min and 52.7?¡À?0.1 g/min, respectively. Optimization of screw-pressing process factors can involve the oil recovery yield or quality properties.
  • What is rapeseed oil refining process?
  • Towards this, the crude rapeseed oil needs refining treatments to remove undesirable ingredients and produce higher quality oils [ 5 ¨C 7 ]. Traditional rapeseed oil refining processes generally involve four successive operations: neutralization, degumming, bleaching and deodorization.
  • 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 ¡ãC 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.
  • How is pressed rapeseed oil yield analyzed?
  • Experimentally obtained values of the pressed rapeseed oil yield were analyzed by the RSM, which includes the nonlinear regression method to define the extended quadratic equation and the ANOVA to evaluate the significance of the developed model, the individual factors, interactions, and the goodness of fit at a 95% confidence level.
