• How to cold press rapeseed?
  • To cold press rapeseed using a canola oil press, put the rapeseed into the barrel and press it with the hydraulic oil. The process does not cause high temperatures.
  • What is hot pressed rapeseed oil?
  • Hot-pressed rapeseed oil is obtained through the hot press method, which has a high extraction rate and efficiency. After roasting the canola seeds, the materials are put into the screw oil press. During the pressing process, the canola screw press drives the rotation of the screw shaft, causing the rapeseed in the bale chamber to move forward continuously.
  • What is the rapeseed oil content?
  • The rapeseed oil content in the extracted oil is between 37.5% and 46.3%. Our canola oil extraction machine has two types: canola screw press and canola oil cold press machine, which can achieve both hot pressing and cold pressing.
  • How to press rapeseed in canola oil press?
  • To press rapeseed for canola oil using a press, put the rapeseed into the barrel. Press it with hydraulic oil without causing high temperature. After pressing, take out the cake or press it again.
  • 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.
  • 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.
