Distillers grains

Andrew Mark Cuomo ( KWOH-moh; born December 6, 1957) is an American politician, author, and lawyer serving since 2011 as the 56th governor of New York. A member of the Democratic Party, he was elected to the same position his father, Mario Cuomo, held for three terms. Born in New York City, Cuomo is a graduate of Fordham University and Albany Law School of Union University, New York. He began his career working as the campaign manager for his father, then as an assistant district attorney in New York City before entering private law practice. He founded Housing Enterprise for

There are two main sources of these grains. The traditional sources were from brewers. More recently, ethanol biofuel plants are a growing source. It is created in distilleries by drying mash, and is subsequently sold for a variety of purposes, usually as fodder for livestock (especially ruminants). Corn-based distillers grains from the ethanol industry are commonly sold as a high protein livestock feed that increases efficiency and lowers the risk of subacute acidosis in beef cattle.Recently, studies indicate that dried distillers grains with solubles (DDGS) as a food source for human consumption may have some benefit in reducing heart disease risk.

Dried distillers grains with solubles (DDGS) is WDG that has been dried with the concentrated thin stillage to 10–12% moisture. DDGS have an almost indefinite shelf life and may be shipped to any market regardless of its proximity to an ethanol plant. Drying is costly, as it requires further energy input. In the US, it is packaged and traded as a commodity product.

Distillers grains are a cereal byproduct of the distillation process. Brewer's spent grain usually refers to barley produced as a byproduct of brewing, while distillers grains are a mix of corn, rice and other grains.

In beer or whiskey production, grains, such as corn, are put through a mashing process, where grain is ground and added to hot water. The starch in the grains undergoes saccharification by enzymes, turning the starch into sugars that are released into the water. The water is removed from the grain, and becomes wort for brewing. The remaining grain, called "spent grain" for the removal of simple sugars and starch, can then be sold as a by-product.

The conversion rate of grains to ethanol and distillers grains varies with the different types of grains and the process used. The details are outlined below:

The conversion rate of corn to distillers grains is: One tonne of corn produces 378 L of ethanol and 479 kg WDG (70% moisture content), or 309 kg of DDGS (10% moisture content).

The conversion rate of wheat to distillers grains is: One tonne of wheat produces 372 L of ethanol and 457 kg WDG (70% moisture content), or 295 kg of DDGS (10% moisture content).

Wet distillers grains (WDG) contain primarily unfermented grain residues (protein, fibre, fat and up to 70% moisture). WDG has a shelf life of four to five days. Due to the water content, WDG transport is usually economically viable within 200 km of the ethanol production facility.
