How does corn oil extraction affect ethanol production?
Most ethanol producers¡¯ corn oil extraction efforts leave roughly 60 percent of the available distillers¡¯ corn oil (DCO) behind. Using Trucent technology and services, it¡¯s not unusual for a plant to add millions of dollars in annual revenue by merely improving their DCO extraction¨Cwithout detracting from your existing DDGS and ethanol production.
How is corn oil extracted?
Almost all corn oil is expeller-pressed, then solvent-extracted using hexane or 2-methylpentane (isohexane). The solvent is evaporated from the corn oil, recovered, and re-used. After extraction, the corn oil is then refined by degumming and/or alkali treatment, both of which remove phosphatides.
Can a high-shear extrusion system extract oil from corn germ?
As technologies continue to advance, high-shear extrusion systems may offer a more efficient alternative for extracting oil from wet processed corn germ. Extrusion systems like the Anderson Dox? Extruder eliminate the need for separate steam heating and drying steps required in traditional stack cooking vessels.
What is corn oil used for?
Corn oil (North American) or maize oil (British) is oil extracted from the germ of corn ( maize ). Its main use is in cooking, where its high smoke point makes refined corn oil a valuable frying oil.
