  • 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.
  • Which raw materials do not release oil by expelling?
  • Some raw materials do not release oil by expelling, the most notable being rice bran. To remove oil from commodities that do not respond to expelling or to extract the final traces of oil after expelling, it is necessary to use solvent extraction .
  • 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. [ 2]
