• 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).
  • What is groundnut oil processing process?
  • Groundnut oil processing process, based on mechanical pressing technology, is generally grouped into three stages: groundnut seeds preparation, groundnut pressing and rude groundnut oil refining. First of all, the groundnut seeds need a thorough cleaning process to remove sand, stalk, plant debris and any other impurities.
  • How does a groundnut oil machine work?
  • The machine’s screw warm pressed the groundnut seeds as it moves to advance where the space is smaller and smaller. Due to strong frication and high pressure, groundnut oil is pressed out. Besides, as the temperature in the machine’s pressing chamber rises, the output rate of groundnut oil also increases.
  • How groundnut oil is produced?
  • Second, the well prepared seeds are conveyed to the screw pressing machine, which is the most popular method of groundnut oil production. The machine’s screw warm pressed the groundnut seeds as it moves to advance where the space is smaller and smaller. Due to strong frication and high pressure, groundnut oil is pressed out.
