• Is a groundnut oil machine suitable for commercial use?
  • At a regulated heater temperature of 100oC the quality of the oil and groundnut cake was pleasant and edible. Based on the efficiency and the quality of the oil produced, this machine was recommended suitable for the production of groundnut oil for commercial use.
  • 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.
  • How to improve the performance of the oil extraction machine?
  • Also the incorporation of sensors in the feed screw in other to avoid the over loading of the machine should be duly considered. As a result of the observation made during the test run, we also recommend that in subsequent design, the oil extraction rate and residual oil in cake should be analyzed to improve on the machine effectiveness.
