Starch based Ethanol

A variety of starch rich material can be used for ethanol production by fermentation (Barley, Cassava roots, Corn/Maize, Potato, Rice, Sorghum Grain, Sweet Potato, Wheat, Rye…). Selection of the appropriate feedstock depends on a number of factors, not the least of which is the geographical / climatic environment of the intended production site.

On top of the sugar-based process here above, DSEC takes particular care to DDGS drying (and possibly pelletizing).

The process proposed by DSEC generally includes:

  • Milling
  • Mashing
  • Enzymatic break down of starch
  • Fermentation with standard yeast (batch or continuous)
  • Distillation
  • Rectification (if applicable)
  • Ethanol dehydration (molecular sieve)
  • Decantation
  • Evaporation
  • DDGS drying (and possibly pelletizing)
