  • How does a rapeseed oil press machine work?
  • With the aid of feeder, the roasted rapeseeds enter the canola oil press machine. The worm rotates along with the main shaft to push the materials forward. With the reducing of the volume of the pressing chamber, the pressure within the chamber increases gradually. Rapeseed oil press machine is equipped with the automatic barrel heating system.
  • 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 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 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.
