Dry Fractionation Process

Fractionation is a process that splits the corn kernel into three separate fractions, endosperm, bran and germ. After being split, only the endosperm enters the ethanol production process. This offers benefits in the ethanol production process including increased yield, lower enzyme usage, reduced emissions, less facility maintenance, and decreased natural gas usage. The process also creates three distinct byrpoducts, in addition to ethanol, including:

- High Protein Dried Distillers Grains

- Corn Germ

- Corn Fiber

High Protein Dried Distillers Grains (HPDDGs)

The first byproduct of fractionation is high protein dried distillers grains (HPDDGs). The higher protein content, combined with the lower oil and fiber content, differentiates this product from traditional dried distillers grains. HPDDGs are ideally suited for the dairy and, to a slightly lesser extent, the beef market. This product can also be fed in higher feed rations to the swine and poultry market due to its low fiber and high protein content.

Corn Germ

A second byproduct of the fractionation process is corn germ. The germ contains the majority of the kernel corn oil and is loaded with key limiting amino acids such as lysine that is ideally suited for animal feed markets.

Corn Bran

The final byproduct produced from fractionation is corn bran. Due to the high fiber content of the bran, this product is ideally suited as a feedstock element for the beef and dairy market. Additionally, corn bran represents the first step in cellulosic ethanol, as developing technology will soon allow us to convert the bran into ethanol.
