Increasing ethanol yield through fiber conversion in corn
2018-12-1 Conversion of corn fiber to ethanol in the dry grind process could increase ethanol yields, reduce downstream processing costs and improve overall process profitability. This work investigates the in-situ conversion of corn fiber into ethanol (cellulase addition during simultaneous saccharification and fermentation) during dry grind process.

Corn-to-ethanol process - Chemical Engineering News
2006-10-23 It is the 25% energy gain from corn to ethanol cited in this paper that Lester warns us about. To the authors, even this positive balance is moot, since ultimately, cellulose from energy crops such as switch grass, not cornstarch, will serve as the raw material for ethanol-producing biorefineries.

Dry-grind process for fuel ethanol by continuous
Conversion of a high-solids saccharified corn mash to ethanol by continuous fermentation and stripping was successfully demonstrated in a pilot plant consuming 25 kg of corn per day. A mathematical model based on previous pilot plant results accurately predicts the specific growth rate obtained from these latest results.

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 ...

Effect of corn preparation methods on dry-grind ethanol
2022-3-1 The mean particle diameter d (50) for preparations varied with set-ups and ranged between 210 and 340 μm for ground corn, and 1180-1267 μm for flaked corn. The ethanol concentrations in beer were similar (18-19% v/v) for ground and flaked preparations, however, ethanol productivity increased with reduced particle size.
