• What is an oil expeller press?
  • But that¡¯s not our focus today. An expeller press ¨C also referred to as an oil press, oil expeller, or oil expeller machine ¨C is employed when you want to use the mechanical extraction process. This technique is fairly straightforward: it uses pressure to extrude oil from the seeds, nuts or other oil-bearing materials.
  • 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.
  • What is an oil extraction machine?
  • This machine is commonly used in commercial or industrial where there is a need for large-scale oil production. They are engineered to efficiently process significant quantities of oilseeds or nuts, ensuring high productivity and optimal oil extraction yields.
  • How does an expeller press work?
  • This technique is fairly straightforward: it uses pressure to extrude oil from the seeds, nuts or other oil-bearing materials. Generally, an expeller press comprises a screw inside a cylindrical shaft within which the oil-bearing material is crushed (with the friction also generating some heat).
  • What is the difference between expeller pressed oil and solvent-extracted oil?
  • Expeller-pressed oils can also be RBD and/or winterized the same as solvent-extracted oils (physical or chemical). Expeller pressing removes about 87-95% of the oils from the nuts/seeds, making it the second most efficient. Cold-processed oils cannot exceed 122¡ãF during the extraction process.
  • What temperature can an expeller press be used for?
  • In the case of harder nuts (which require higher pressures) the material can exceed temperatures of 120 ¡ãF (49 ¡ãC). An expeller press is a screw-type machine that mainly presses oil seeds through a caged barrel-like cavity. Some other materials used with an expeller press include meat by-products, synthetic rubber and animal feeds.
