The corn oil extraction machine, also known as screw oil press machine, is used for the mechanical pressing of corn germ oil. The corn germ oil press machine adopts directional pressure bearing and multi-stage propulsion to realize high oil yield.
What is the process of corn oil machine?
Complete Set of Corn Oil Machine for Small Scale Corn Oil Processing Plant Process Flow : Maize Germ → Screening (sieving machine) → Cooking (Roaster) → Oil Expelling (Corn Oil Press Machine) → Filtering (Filter Press) → Refining (Refinery Machine) → Corn Germ Oil
How is corn oil extracted?
Oil is being pressed from the germ using a heated screw press, which can yield as much as 50 percent of the germ oil. Then the pressed oil should be extracted in the corn oil extraction plant, the remaining oil is stripped from the "press cake" with the solvent hexane, a volatile by-product of gasoline production.
What is the extraction rate of corn oil?
At present, most corn oil companies or factories use screw pressing process, the oil yield is around 65%~70%, while for large oil mills adopting solvent extraction technology, the corn germ oil extraction rate can reach 98%. Complete Corn Oil Extraction Process (Solvent Extraction)
