The given diagram reveals the procedures that result in ethanol fuel products made from corn.
Overall, there are nine stages involving ethanol making, starting with the harvest of corn and coming to an end with ethanol fuel being transported.
The first stage commences with the corn-picking process. Once collected, corn is selected and stored in a favorable room which helps preserve and maintain the quality of corn. Afterward, corn is moved to the specialized machine and milled. Then, being milled, corn powder is cooked over direct heat for 4 hours. This step involves the removal of water. When finished, the cooked corn powder is fermented for 48 hours, and following, workers need to separate and take the solid waste apart from the liquid ones. This liquid product needs to be purified for 5 hours to dispose of any impurities before being stored and transported to the consumption plant.
