• 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 is a French screw press?
  • French screw presses, sometimes referred to as oil expeller press machines, are well known throughout the oilseed industry for their rugged construction and outstanding durability. We pride ourselves in partnering with customers to design and supply oil extraction machines and preparation equipment that best meet their needs.
  • 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.
  • Who invented the oil expeller press?
  • The original oil expeller press was invented in the late 1800s by Anderson International¡¯s founder, Valerius D. Anderson. This patented mechanical screw press design was a radical departure from hydraulic presses used at the time.
  • 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).
  • What were the advantages of a mechanical screw press?
  • This patented mechanical screw press design was a radical departure from hydraulic presses used at the time. The Anderson expeller¡¯s primary advantage was that it allowed for continuous oil extraction and the processing of large quantities of materials with minimal labor.
