• What are expeller pressed oils?
  • Consumers are more worried than ever about the origin and the ingredients of the foods they consume but what are expeller pressed oils and why are these considered healthier oils? Expeller pressing is the mechanical method for extracting oil from seeds and nuts.
  • Is expeller pressing better than solvent expelled?
  • Expeller pressing gets 87-95% of the oil out of the seed, so there is some oil still left over after pressing (though some claim as little as 65% is removed, so this is debated). Therefore, this option is not the cheapest, which can make this oil more expensive than the solvent expelled standard.
  • What is the difference between expander and expeller?
  • The expander is a unit assigned to seed or product preparation, whereas the expeller is the machine for mechanical oil separation from plant material or similar solid-liquid separation tasks.
  • What is expeller press & how does it work?
  • Expeller pressing is the mechanical method for extracting oil from seeds and nuts. It involves crushing the raw material, such as soybeans, sunflower seeds, or olives using a mechanical press without the use of chemicals or excessive heat.
  • How does a nut oil expeller work?
  • An expeller is a big screw that is tightened until it crushes the nut/seed and causes the oil to run. This method provides yields of only 65-70% of the oil. Many companies then try to extract the rest of the oil using the chemical solvent. Mechanical pressing may create high temperatures, especially when squeezing hard nuts.
  • What is the difference between expeller pressed and cold pressed oil extraction?
  • The difference between expeller pressed vs cold pressed oil extraction is that during the latter process, the fruit/nuts/seeds are pressed using either a bladder press (used with softer fruits), hydraulic press, or low resistance expeller pressing so as not to exceed the 122¡ãF temperature requirement.
