Removing Fiber from DDGS Results in Superior Product for Swine
by Holly Jessen (Ethanol Producer Magazine) Removing fiber from dried distillers grains with solubles using the elusieve process results in an enhanced product with greater nutritional value for growing and finishing pigs, according to a study conducted by researchers at the University of Illinois, Urbana.
The elusieve process separates fiber from DDGS by blowing air through DDGS that has been separated by particle size. “[It’s] similar to separating chaff from wheat,” according to a website about the process. Not yet being used at commercial scale, the elusieve process is being researched at pilot scale at Mississippi State University, which has the equipment to separate fiber from one ton of DDGS an hour, according to Radhakrishnan Srinivasan, assistant research professor at MSU’s department of agricultural and biological engineering.
…By removing the fiber, about 10 percent of the material is removed. The fiber can be used for many things, such as feed for ruminants, a fuel source, feedstock for cellulosic ethanol, polymer composites and corn fiber gum production, he said. The elusieve process can also be used to remove fiber from corn flour before fermentation, Srinivasan added. Doing that would increase ethanol productivity and produce low-fiber DDGS without the need to separate it at the back end.READ MORE and MORE (Elusieve Process) Abstract
