• What is expeller pressed castor oil?
  • This method ensures a purer, more beneficial oil, particularly suited for hair and skin applications, thanks to its unaltered nutrient profile. Expeller-pressed (often referred to as regular castor oil) is obtained by mechanically pressing castor seeds, generating high heat through friction.
  • How to Mill castor oil?
  • It is usually done using a high pressure, which uses continuous screw press with the help of a seed oil press machine. The extracted castor oil is sprinkled. The material that is extracted from the press is called castor cake. Just feel free to inquiry for customized oil milling plant and cost.
  • What is the difference between expeller pressing & cold pressing castor oil?
  • Expeller pressing can expose the oil to temperatures up to 210¡ãF, while cold pressing exposes the oil to up to 122¡ãF ¨C so neither method comes close to damaging the oil. But when it comes to heat and extraction methods, it appears that Castor Oil¡¯s nutrients stay intact.
  • How is castor oil extracted?
  • In this process, the oil is extracted using methods such as bladder pressing (for softer fruits), hydraulic pressing, or low-resistance expeller pressing to ensure the temperature stays below 122¡ãF. Sometimes cold water may be run through the machine to keep temperatures cooler. Castor Oil is rich and viscous.
  • What is the expeller pressing method?
  • The expeller pressing method involves physically pressing castor beans to extract the oils, avoiding the use of chemicals. While this technique employs pressure for oil extraction, the pressure itself can generate temperatures between 140-210¡ãF, so it is not considered a true ¡°cold processed¡± method.
  • Can castor oil withstand high temperatures?
  • Castor Oil has a high stability level that makes it able to withstand high temperatures. Castor Oil¡¯s nutrients do not begin to break down until the oil is exposed to 302¡ãF (150¡ãC). Expeller pressing only exposes the oil to 140-210¡ãF (60-99¡ãC).
