Distillers dried grains with solubles (DDGS), a co product of the corn-based fuel ethanol industry, is used widely as an animal feed. Due to increased demand for DDGS in livestock markets it has become essential to transport DDGS over long distances. Flowability problems in DDGS, due to particle caking, often create nuisance in storage and transportation. Materials above the glass transition temperature (Tg) can exist in a “rubbery state,” this condition can often be responsible for structural collapse, particle agglomeration, and caking of materials. This study investigated the effects of varying CDS (10, 15, and 20%, wb), drying (100, 200, …

Demand for alternative fuels and the need to reduce dependence on fossil fuels, have triggered the growth of corn-based ethanol production, and this is expected to rise in future years. Transportation of the co-product distillers dried grains with solubles (DDGS) from this industry occurs under various environmental conditions. It is often problematic, since caking between the particles can lead to flow problems. In this study we have prepared DDGS by combining condensed distillers solubles (CDS) with distillers wet grains (DWG) and then drying. We investigated the effects of CDS (10, 15, and 20% wb), drying temperature (100, 200, and 300°C), …
