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 are the features of corn germ oil press machine?
The corn germ oil press machine adopts directional pressure bearing and multi-stage propulsion to realize high oil yield. Scientific heating, automatic control of pressing temperature, high quality of pressed corn oil are among the outstanding features.
What is corn germ oil?
Corn germ oil is a by-product of the corn oil milling process. Most corn that is harvested is used as feed but the proportion of the corn that is milled is increasing because of bioethanol production. During the wet milling process, the germ is isolated from the starch using cyclone separators, washed, and dried.
How is corn germ extracted from starch?
During the wet milling process, the germ is isolated from the starch using cyclone separators, washed, and dried. The dried germ contains about 50% oil, in which the oil constitutes about 85% of the total amount of oil present in the corn. The oil is produced by first expelling the germ and then extracting the expeller cake with n -hexane.
