• What is an oil expeller press?
  • French custom designs, manufactures and supports oilseed preparation equipment and screw presses, sometimes referred to as oil expeller presses. These oil extraction machines gather vegetable oil from oil-bearing seeds and nuts for food and industrial uses, including biodiesel and other fuels.
  • 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.

  • Today, French stands as a leading supplier and innovator of oil extraction machines and mechanical oilseed screw presses. French has provided thousands of roller mill and mechanical screw presses around the world, processing all major oilseeds with customers in more than 80 countries.
  • How does expeller pressing work?
  • The oil seeps through small openings that do not allow seed fiber solids to pass. Afterward, the seeds are formed into a hardened press cake, which is removed from the machine. Pressure involved in expeller pressing creates heat in the range of 140¨C210 ¡ãF (60¨C99 ¡ãC).
  • When did expeller presses start?
  • The earliest expeller presses utilized a continuous screw design. The compression screws were much like the screws of a screw conveyor ¡ªthat is, the helicoid flighting started at one end and ended at the other. Valerius Anderson invented the interrupted screw design and patented it in the year 1900.
