- Heating or Hardening
Clean castor seeds then are heated or cooked to remove the moisture, which is very important process before oil extraction since it helps to improve the oil yield.
- Oil Pressing
Screw oil press is adopted to press the castor seeds and the oil is released out. The castor oil press machine expeller is a high-pressure continuous screw press to extract the oil.
