  • 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 an expelling machine for extracting oil from groundnut seeds?
  • An expelling machine for extracting oil from groundnut seeds was designed and fabricated for market oriented production. The procedures employed the design stage, construction and testing. The machine components are: the speed reduction gear, expellant unit, drains collector, driving and driven pulleys, and the hopper.
  • 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 much oil can be extracted from groundnut?
  • Oil extracted from groundnut by traditional means can produce about 20-30% from the groundnut whereas the mechanical methods will yield a higher percentage. A mechanical means of extracting oil was designed, constructed with locally available materials and tested for groundnut oil extraction.
  • How does a groundnut expeller work?
  • The expeller is driven by a 3hp electric motor via a reduction gear. The expelling unit consists of a screw expellant shaft, shown in Fig. 1 below. The heating of groundnut seeds is achieved by generated heat, which heats the surrounding of seeds passage. Fig. 1 Lathe machining of Screw Expellant Shaft.
