  • How much crude oil is extracted by cold pressing rapeseed oil?
  • As a result, the crude oil extraction degree achieved by cold pressing was 60.8% compared to the Soxhlet method. This extraction degree is lower than previously reported for screw pressing of rapeseed [ 16, 17 ]. The obtained pressed rapeseed oil contained about 88.5% of crude rapeseed oil and 11.5% of solid residue.
  • 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 is rapeseed oil extracted?
  • The extraction of the seed oil was done in triplicate. 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).
  • Can mechanical pressing be used for rapeseed oil extraction?
  • The investigation of mechanical pressing for rapeseed oil extraction has been limited. In one study, a screw-pressing method achieved an extraction degree of 72% [ 16 ]. Another study using a 'duo' screw press demonstrated a higher extraction degree of 82.6% [ 17 ].
