  • What is an expeller press?
  • 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. Raw materials enter one side of the press and waste products exit the other side.
  • 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.
  • 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 °F (49 °C). 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.
  • 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.
  • 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 °F (60¨C99 °C).
  • What is the output of an oil expeller machine?
  • After pressing, the oil expeller machine produces crude oil and oil cake. 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.
