Bioethanol production

The bioethanol production involves three steps: liquefaction, saccharification, fermentation and distillation.

The reactors loaded with reagents are heated by means of the double envelope. The stirring systems ensure

the homogeneity of the mixture and promotes heat transfer to the wall. The vapors rise in column are then condensed.

A reflux head allows you to choose to work at total reflux or total withdrawal. The condensate is cooled.

The touch screen allows one to record pH and temperatures in order to study their influences on the process.

Pretreatment

Reduction

Liquefaction: reduction dextrins

Saccharification: production of glucose and maltose

 

Fermentation

 

Distillation: separation of bioethanol
