DDGS DRIED DISTILLER GRAINS WITH SOLUBLES In for example beer or whiskey, production grains, such as corn, wheat, rice are ground to a coarse consistency and added to hot water. After cooling, yeast is added and the mixture ferments for several days to one week. The solids remaining after fermentation are the distillers grains. Distillers Grains are a cereal byproduct of the distillation process. There are two main sources of these grains. The traditional sources were from brewers. More recently, ethanol plants are a growing source. It is created in distilleries by drying mash, and is subsequently sold for a variety of purposes, usually as fodder for livestock. Corn based distillers grains from the ethanol industry are commonly sold as a high protein livestock feed that increases efficiency and lowers the risk of subacute acidosis in beef cattle. Wet and dry distillers grains There are two common types of distillers grains. Wet Distillers Grains (WDG) contain primarily unfermented grain residues (protein, fibre, fat and up to 70% moisture. DDGS Plant WDG has a shelf life of four to five days. Due to the water content, WDG transport is usually economically viable within 200 km of the ethanol production facility. Ensures high energy, protein and digesta- Dried Distillers Grains with Solubles (DDGS) is WDG that has been dried with the concentrated thin stillage to 10-12 per cent moisture. DDGS have an almost indefinite shelf life and may be shipped to any market regardless of its proximity to an ethanol plant. Drying is costly, as it requires further energy input. It is packaged and traded as a commodity product. Physical and chemical properties of DDGS vary among sources and can influence its feeding value, handling, and storage characteristics. These include color, smell, particle size, bulk density, pH, color, thermal properties, flowability, shelf life stability, and hygroscopicity.

The water and solids remaining after distillation of ethanol is called whole stillage, comprised primarily of water, fiber, protein and fat. This mixture is centrifuged to separate coarse solids from liquid. The coarse solids are also called wet cake and contain about 35% dry matter. Wet cake can be sold to local cattle feeders without drying, or dried to produce dried distiller’s grains (DDG). The liquid, now called as thin stillage, goes through an evaporator to remove additional moisture and the resulting co-product is called condensed distiller’s solubles which contains approximately 30%...

The back-mix flow principle With the back-mix flow principle the feed product is mixed with partly dried product. It is used for feed products which need a degree of drying in order to fluidize properly. The back-mix flow provides a relatively wide product residence time distribution. DDGS The wet cake from the filter press will be mixed with condensed distiller’s solubles and dried to produce distiller’s dried grains with solubles. The product temperature and moisture content remains uniform throughout the fluidized layer. By controlling the powder layer in the Back Mix Fluid Bed, residence...
