Dry Grind Ethanol Biorefinery ABQ. Dry-grind ethanol industry was very profitable in the past. However, due to the sharp decline in crude oil price, the profits from ethanol in 2015 fell sharply (Irwin and Good, 2015; Wisner, 2015). Since the ethanol plants are still in the low margin time for ethanol

Most recently built ethanol plants are the dry grind type. This is due to the reduced initial cost of the processing facility and the increased ethanol produced per bushel of (Bothast and Schlicher, 2005).

What is Dry Grinding?

Ethanol production also uses dry grinding, but it has a longer process that has many steps in common with wet grinding. After the is broken down, often through machine force in a hammer مطحنة , it goes into a storage chamber where it is kept wet. This allows the material to ferment and eventually become ethanol.
