DDGS
(Dry Distillers Grain Soluble:_________________________________________
DDGS is obtained as a bi-product from a grain distillery.
Slops from distillation column are concentrated in multiple
effect evaporators and the concentrated slope is added on the
decanted residue obtained from the fermentation process, which
are mainly proteins and the fibrous material of the grain.
This mixture of the concentrated slope and the residue is dried
in indirectly heated rotary dryer or steam tube dryer to obtain
DDGS which is used as cattle feed and the distillery truly
becomes zero discharge.
