The Quality Of Alcohool Is Very Important To Develop The Perfume

In USA, corn is the most widely used raw material to produce alcohool. There are two different processes: dry or wet grindings. 

The Figure 2 shows the differences.The dry milling technique enables to immediately grinds the grains then undergoes fermentation after liquefaction and saccharification.

The residues that can not be fermented is used as animal feed. In comparison, the Figure 3 shows the wet mill technology.This different process requires a production scale around twice as large as of the one of the dry technology.
