  • 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.
  • Does process factor affect rapeseed oil yield?
  • Multiple nonlinear regression and analysis of variance (ANOVA) were employed to develop a polynomial model, investigate the process factor¡äs effects on the rapeseed oil yield, evaluate the developed model's statistical significance, and determine the optimal conditions for reaching the maximal rapeseed oil yield.
  • 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 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 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.
