Bioethanol production dry-mill mash preparation


The main fuel used as gasoline substitute for road transport vehicles is bioethanol. Ethanol or ethyl alcohol (C2H5OH) fuel is mainly produced by the sugar fermentation process.

The Dry Mill process of producing Motor Fuel Grade Ethanol (MFGE) using corn as the feedstock consists of six steps: 

  1. Grinding
  2. Cooking
  3. Fermentation
  4. Distillation
  5. Dehydration
  6. Non-fermentables separation

Vaisala K-PATENTS® Process Refractometer PR-43-G is installed directly in the main line or in a by-pass. The refractometer provides continuous indication of the concentration throughout the process with excellent repeatability.
