• 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.
  • How does an expeller press work?
  • An expeller press is a screw type machine, which presses oil seeds through a caged barrel-like cavity. This machine uses friction and continuous pressure from the screw drives to move and compress the seed material. The oil seeds through small openings that do not allow seed fiber solids to pass through.
  • Can expellers be used with oilseeds & nuts?
  • Expellers can be used with almost any kind of oilseeds and nuts. The process is relatively simple and not capital-intensive. While the smallest solvent extraction plant would have a processing capacity of 100-200 tons per day, expellers are available for much smaller capacities, from a few tons per day and up.
  • How do you extract oil from seeds?
  • The two most common processes to extract oil for most seeds, beans, and nuts is the Full Press Extraction Process where mechanical screw presses are used to extract the oil by squeezing the oil under high pressure, and the Preparation/Solvent Extraction Process where a solvent is mixed with the material to separate the oil.
  • Who is French oil extraction machine & screw presses?
  • 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.
  • What is the difference between a solvent extraction plant and an expeller?
  • While the smallest solvent extraction plant would have a processing capacity of 100-200 tons per day, expellers are available for much smaller capacities, from a few tons per day and up.There are no solvent (chemical) residues in oil that has been expeller pressed resulting in a cleaner more pure oil, higher in natural colors and flavors.
