A series of computer models of the ethanol process and production economics have been developed by ARS engineers conducting research to reduce ethanol costs.

Ethanol Production Dry versus Wet Grind Processing

The majority of U.S. ethanol production is from dry-grind technology. The traditional dry-grind process grinds the whole corn kernel and mixes it with water and enzymes. The mash is then cooked to liquefy the starch further. The mash is then cooled and mixed with more enzymes to convert the remaining sugar polymers to glucose before fermenting

A hammer mill is used to grind maize to the desired particle size prior to jet cooking, liquefaction, saccharification, and fermentation. Recently, this process is being referred to by the name “Dry Grind Ethanol” in order to prevent confusion.

Production of ethanol from winter barley by the EDGE

This fact, along with a lower starch content than corn, makes ethanol production at the commercial scale a real challenge. A new fermentation process for ethanol production from Thoroughbred, a winter barley variety with a high starch content, was developed. The new process was designated the EDGE (enhanced dry grind enzymatic) process.
