Extrusion trials were conducted with varying levels of DDGS along with soy flour, corn flour, fish meal, vitamin mix, mineral mix and net protein content adjusted to 28% in a Wenger TX-52 twin screw extruder. The properties of extrudates obtained with experiments conducted in full factorial design with 3 levels of DDGS content, 2 levels of moisture content and 2 levels of screw speed were studied. Increasing the DDGS content from 20% to 60%, resulted in 36.7% decrease in the radial expansion leading to 159%, 61.4% increase in the unit density and bulk density of the extrudates. Increasing the DDGS …

The goal of this study was to investigate the effect of die nozzle dimensions, barrel temperature profile, and moisture content on DDGS-based extrudate properties and extruder processing parameters. An ingredient blend containing 40% distillers dried grains with solubles (DDGS), along with soy flour, corn flour, fish meal, whey, mineral and vitamin mix, with a net protein content adjusted to 28% was extruded in a single-screw laboratory extruder using seven different die nozzles. Increasing moisture content of the ingredient mix from 15 to 25% resulted in a 2.0, 16.0, 16.3, 22.9, 18.5, 32.5, and 63.7% decrease, respectively, in bulk density, water-solubility …
