corn oil extraction process

We are one of the world leading companies in corn oil extraction. KMEC enjoys good reputation all over the world.

Corn oil not only can be used as cooking oils but is also a feedstock used for biodiesel. Other industrial uses for corn oil include soap, salve, paint, rustproofing for metal surfaces, inks, textiles, nitroglycerin, and insecticides. It is sometimes used as a carrier for drug molecules in pharmaceutical preparations.

Inedible corn oil is an emerging co-product for the ethanol industry. Today, about 1/3 of all ethanol plants in production are producing some type of inedible corn oil.

Corn Oil Extraction Process

Oil is expelled from the germ using a heated screw press, which can yield as much as 50 percent of the germ oil. And the remaining oil is stripped from the "press cake" with the solvent hexane, a volatile by-product of gasoline production. (Hexane is introduced to the cake bed with an exposure time as brief as possible so that hexane residual in the oil will be limited.) The corn oil in the hexane solution is heated to vaporize the volatile solvent, which is captured as a condensate and used again. Then the heat expelled and hexane extracted oils are combined as crude corn oil; the remaining cake is processed for livestock feed.

We have rich and pratical experience in manufacturing and exporting a wide range of corn oil processing machinery. We also design complete corn oil processing plant. Write to to get more info.
