• 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 does an expeller press work?
  • An expeller press or ¡°screw press,¡± is a machine that presses seeds and nuts through a cavity and uses intense friction and pressure to extract oil. During this process, there isn¡¯t any added heat but since the seeds are pressed using friction, heat is created (around 140-210? F). Once the seeds are pressed, the oil is removed.
  • What is castor oil press machine?
  • Castor oil press machine is used for pressing castor bean for oil. There are semi-automatic castor oil press and automatic castor oil press. The castor oil produced is used for industrial applications and the residual oil rate is 6-8%. Castor oil machine features convenient operation, easy maintenance, and stable performance.
  • Can an expeller press be a hot press or cold press?
  • An expeller press can become a hot press or a cold press, depending on the steps you take upstream before extraction. Equating an expeller with hot pressing isn¡¯t quite accurate because the screw press has nothing to do with the processing temperature.
  • What is expeller pressed oil?
  • Expeller-pressed oils are basically oils extracted by a fancy method called expeller pressing. It¡¯s like a giant mechanical press, squishing seeds or nuts to get the oil out. This method doesn¡¯t involve the use of chemicals or heat, but, yes, natural heat is evolved when machinery takes action.
  • Why is expeller pressing so expensive?
  • When expeller pressing, it takes a large number of nuts or seeds to create a high yield ¨C which means more money. This is one of the biggest reasons why oil manufacturers aren¡¯t keen on using this method of extraction and instead use methods that include chemicals and high heat.
