On The Physical Properties Of Distillers Dried Grains With Solubles (Ddgs), Klein Ileleji, Kurt A. Rosentrater Jul 2008

On The Physical Properties Of Distillers Dried Grains With Solubles (Ddgs), Klein Ileleji, Kurt A. Rosentrater

Kurt A. Rosentrater

Distillers dried grains with solubles (DDGS) is a complex heterogeneous granular solid that exhibit a wide range of physical and chemical properties. This fact is one of the major reasons that livestock nutritionists often find it difficult to include it in their feed rations. The rapid growth of the corn ethanol industry, the primary generator of DDGS, has resulted in a huge influx of this product into the marketplace. Unfortunately, the lack of standard methods for product quality determination and reporting is becoming a bottleneck to expanding the market for this product. Challenges in the logistics of moving DDGS through ...


Surface Characteristics And Flowability Of Distillers Dried Grains With Solubles, Rumela Bhadra, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan Jun 2008

With an annual production of approximately 6.5 billion gallons of fuel ethanol, and projected growth for the foreseeable future, supplies of coproducts such distillers dried grain with solubles (DDGS) are anticipated to continue to grow as well. DDGS is used primarily as livestock feed. Much of the DDGS must be shipped, often over large distances throughout the country, as much of the livestock (especially large dairies and feedlots) are outside the Corn Belt, where most of the ethanol plants are currently located. “Caking”, or stickiness, among particles is an important issue related to DDGS, especially when it leads to ...


Understanding And Modeling Flowability Of Ddgs, Rumela Bhadra, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan Jun 2008

Understanding And Modeling Flowability Of Ddgs, Rumela Bhadra, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan

Distillers dried grains with solubles (DDGS), the major coproduct from the corn-based fuel ethanol industry, is primarily used as livestock feed. Due to high protein, fiber, and energy contents, there is a high demand for DDGS. Flowability of DDGS is often hindered due the phenomenon of “caking”. Shipping and handling of DDGS has thus become a major issue due to bridge formation between the DDGS particles. The objective of this investigation was to measure flowability characteristics of DDGS samples from five ethanol plants in the north central region of the U.S. Carr and Jenike tests were performed, and the ...


Effect Of Flow Agent Addition On The Physical Properties Of Ddgs With Varying Moisture Content And Soluble Levels, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan, Vykundeshwari Ganesan Jan 2008

Effect Of Flow Agent Addition On The Physical Properties Of Ddgs With Varying Moisture Content And Soluble Levels, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan, Vykundeshwari Ganesan

Distillers Dried Grains with Solubles (DDGS) is widely recognized as a highly nutritious animal feed ingredient. With the exponential growth of the fuel ethanol industry in the past several years, significant quantities of distillers grains are now being produced. To effectively utilize these feeds in the domestic market, these coproduct streams have to be transported greater distances, and must be stored in various structures until final use. Unfortunately, DDGS flow is often problematic, as it frequently becomes restricted by caking and bridging during storage and transport. This issue may arise from a number of factors, including storage moisture, temperature, relative ...


Potential Bleaching Techniques For Corn Distillers Grains, Jessica A. Saunders, Kurt A. Rosentrater, P. G. Krishnan Jan 2008

Potential Bleaching Techniques For Corn Distillers Grains, Jessica A. Saunders, Kurt A. Rosentrater, P. G. Krishnan

The ethanol industry is booming and extensive research is now being pursued to develop alternative uses for Distillers Dried Grains (DDG) and Distillers Dried Grains with Solubles (DDGS), coproducts of the ethanol production process. Currently, DDG and DDGS are used exclusively as livestock feed. The low starch, high protein and high fiber coproducts appear to be ideally suited for diets treating medical conditions such as diabetes and Celiac’s disease by virtue of their chemical composition. Processing methods need to be investigated to create flours that can be used effectively. Modifying aspects such as color, odor and baking functionality may ...
