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

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

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 ...
