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. Srinivasan studied the process at the University of Illinois while completing his doctorate and now works at MSU.
