• 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.
  • 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.
  • 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).
  • How oil expeller Machine Works?
  • The working principle of the oil expeller machine is to forcefully push the oilseeds and nuts through the barrel by the action of the revolving worm. Due to increased pressure of worms, the oil squeezed out from the seeds and turns out through holes. After pressing, the crude oil and oil cake are obtained.
  • 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.
  • What are the parts of oil expeller machine?
  • This includes body, kettle, main shaft, gears, worms, bearings, barrel, cutter, cone and collar. To rotate the cage, the screw shaft is provided with the gear assembly. The following are the parts involved in the manufacture of oil expeller machine.
