Small groundnut oil mill machinery connects a series small oil processing equipment together to achieve continuous oil extraction. Because it is fully mechanical driven, it can accomplish easier operation and high rate of oil yield. By the way, it can deal with almost all kinds of oil seeds.
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 manufacturing process?
Groundnut oil manufacturing process is divided into two methods, the first is mechanical pressing and the second is solvent extraction. Mechanical pressing can extract 85% oil and the remaining oil is extracted by the solvent extraction method.
What is groundnut oil?
Groundnuts are also known as Peanut or Earthnut. The oil content in the peanuts is between 35% and 45% depending on the variety. Groundnut oil extraction involves several processes including groundnut decortication, cleaning, seed conditioning, crushing and filtration.
