Ingredient blends containing 28% protein with distillers dried grains with solubles, soy flour, corn flour, fish meal, mineral mix and vitamin mix was extruded in a C.W. Brabender single screw laboratory extruder using 7 different die nozzles. The die nozzle diameter (D), length (L) and L/D ratio of the dies were in the range of 2.0 mm to 6.0 mm, 10.0 mm to 30.0 mm and 3.33 to 10.00, respectively. The moisture content of the ingredient mix was varied from 15% to 25% and the temperature of the transition zone and die section were varied from 100° C to 140°C. …

With the rapid growth in the fuel ethanol industry in recent years, considerable research is being devoted to determining distillers dried grains with solubles (DDGS) nutritional properties and to optimizing their inclusion in livestock diets; physical properties of these materials, however, have been largely ignored. Using standard laboratory methods, several physical properties for typical DDGS streams were determined, including moisture content, water activity, thermal properties (conductivity, resistivity, and diffusivity), bulk density, angle of repose, and color. The DDGS samples in this study were golden-brown in color and exhibited physical properties similar to other dry feed ingredients, such as hominy feed, …
