Elusieve process was invented by Radhakrishnan Srinivasan and Professor Vijay Singh (University of Illinois) in 2004 for separating fiber from distillers dried grains with solubles (DDGS). DDGS is the coproduct of the corn-to-ethanol dry grind process. It is analogous to Brewers Spent Grains (BSG). DDGS is a solid ranging from golden yellow to brown in color. It is usually particulate matter and powdery. In the dry grind process, starch in the corn is converted to ethanol and the remaining corn components (protein, fiber, fat and ash) end up as the coproduct, DDGS. DDGS is currently used mainly as cattle feed. Due to high fiber content, DDGS utilization in poultry and swine diets has been limited. Separation of fiber from DDGS opens up new markets, increases nutritional value of DDGS by increasing protein and fat contents, and produces fiber as an additional coproduct.
Elusieve process is the combination of sieving and air classification. As elutriation (upward air flow) was the air classification method that was used in process development, the term “Elusieve” was coined. Elusieve process is simple and needs low investment because it uses standard equipments (sifters and aspirators). Elusieve process has been effective in separating fiber not just from DDGS alone, but corn flour as well. Research is underway to evaluate its effectiveness in barley, wheat and sorghum processing.
