The D.D.G.S. (Distillers Dried Grains with Soluble) production unit aims to reclaim cellulosic fibres coming from the stillage clarification stage (separation / settling) and syrups obtained from the stillage concentration stage.

Both products obtained from the previous stages are treated in a Drying unit supplied by Maguin-Promill. This unit includes Mixture of incoming products, Drying and Granulation.

Mixers, of Maguin-Promill conception, are developed to ensure a perfect mixture of the wet grain, the stillage syrup and the recycled product from drying. The Maguin-Promill dryer has a 3 pass drum, working at low temperature with a short residence time, allowing the preservation of the nutritional qualities of the D.D.G.S. produced.

The dry product is then passed to the Granulation stage, which produces a product suitable for animal feed commercialization.

Recovery of vapours from the dryer also enables energy consumption optimization, due to energy coupling with the distillation unit.
