The diagram illustrates how ethanol fuel (1) from corn. Overall, the process (2) several stages, beginning with storage and (3) in transport of the finished product.

First, harvested corn (4) and subsequently (5) milling to produce a fine powder. The milled material (6) with water for about four hours; during this time the mash (7) continuously.

After cooking the mixture (8) and (9) to fermentation tanks where yeast (10) and the mash (11) for approximately 48 hours.

The mixture (12) into solid by-products and liquid ethanol. The liquid (13) distillation, which (14) around five hours.

After purification, ethanol (15) in tanks and then (16) to fuel stations. The production line (17) both mechanical and chemical operations.

Quality control (18) at several stages to ensure the fuel (19) regulatory standards. Overall, the diagram (20) a clear step-by-step production procedure.
