The diagram shows how ethanol fuel is made from corn. It describes the main steps from the beginning to the end of the process.
Overall, the process starts with storing corn and finishes with transporting the ethanol fuel. There are several stages, including milling, cooking, fermenting, separating, and purifying.
First, corn is stored and then milled into small pieces. After this, the corn is cooked for four hours, and water is added during this stage. Cooking helps prepare the mixture for the next step. Then, the cooked corn is fermented for 48 hours so that ethanol can be produced.
Next, the mixture is separated into two parts: a solid by-product and a liquid. The solid part is removed, while the liquid continues in the process. After that, the liquid is purified for five hours to produce ethanol fuel. Finally, the ethanol is stored and transported to be used.
