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

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, however, these coproduct streams are increasingly being 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, …

Methodology To Determine Soluble Content In Dry Grind Ethanol Coproduct Streams, Vykundeshwari Ganesan, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan Jan 2006

Methodology To Determine Soluble Content In Dry Grind Ethanol Coproduct Streams, Vykundeshwari Ganesan, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan

Distillers grains and syrup are coproducts from fuel ethanol dry grind processing. Ethanol manufacturing is dramatically increasing in the United States, primarily in Midwestern states, and thus the availability of these feed products is also growing. Confusion currently exists in industrial nomenclature regarding "solubles" in these streams because no standards are in place. In our study, dissolved materials were considered soluble matter. We developed a methodology to determine the dry basis soluble content in condensed distillers solubles (CDS) and distillers dried grains with solubles (DDGS). A mass balance analytical approach was initially used, but results were not in good agreement …
