The experience of Maguin-Interis in cereal treatment has been developed from the first "wheat" units working in France in the 1980s and has been enhanced by laboratory studies on other cereals.

Maguin-Interis processes allow the treatment of manioc, wheat, corn, rye, triticale but also new cereals such as grain sorghum, the first studies of which go back to 1996.

Maguin controls all the processing stages from Grinding, supplied by Maguin-Promill, Starch Hydrolysis, Alcoholic Fermentation and Ethanol Separation using Maguin-Interis processes; and stillage (spent wash) treatment with D.D.G.S. production using dryers and granulating presses from Maguin-Promill.

The total command of "key" equipment for the bioethanol plant enables Maguin to develop an internal synergy between the alcohol unit and the D.D.G.S. drying unit, which reduces production costs by reducing steam consumption.
