  • What is groundnut oil expelling machine?
  • Groundnut oil expelling machine is an important device for oil recovery from groundnut seed in a roller mill, direct firing of barrel and pressing with an engine driven oil expeller. Expeller use a horizontal rotating metal screw, which feeds oil-bearing seeds into a barrel shaped outer casing with perforated walls according to Maul et al (2011).
  • How much groundnut can an expeller process?
  • Expeller are power driven, and are able to process 8 to 300kg of groundnut per hour or even more depending upon the type of expeller used (Khangar and Jaju, 2012). Bigger units which process greater quantities of oil are available for use in larger mills.
  • What is groundnut oil expeller?
  • Groundnut oil expeller has been developed and constructed by some researchers in different sizes, shapes and materials, mostly for industrial uses. Such expellers are expensive, involve high level technology which cannot be afforded by small scale and low income oil millers.
  • How does a groundnut oil extraction machine work?
  • A mechanical means of extracting oil was designed, constructed with locally available materials and tested for groundnut oil extraction. The machine consists of the frame, hopper, gear reduction unit and the power shaft. It was powered by a 1 hp three-phase electric motor.
  • Do small scale oil millers need a groundnut oil expeller?
  • In order to assist the small scale oil millers in the local communities, small scale groundnut oil expellers need to be designed, and constructed with locally sourced materials. The main objective is to design and fabricate of an improved, durable groundnut oil expeller, using local sourced materials.
  • How do oil expellers work?
  • Expeller use a horizontal rotating metal screw, which feeds oil-bearing seeds into a barrel shaped outer casing with perforated walls according to Maul et al (2011). The seeds are continuously fed to the expeller, which grinds, crushes and presses the oil out as it passes through the machine (Khangar and Jaju 2012).
