The diagram below shows how ethanol fuel is produced from corn.
The diagram illustrates the process of producing ethanol fuel from corn. Overall, corn passes through 8 stages before being ethanol fuel and ready to use in the gas station. There is a process that grinds corn into flour and ferments it before purifying it into ethanol.
Look at the first stage of making ethanol gas, after harvesting, the corn has stored in the storehouse. Once the corn has milled into flour, it is then added water and cooked in four hours. Following this, this mixture has fermented for 48 hours before moving to the next step.
In the subsequent step, the fermented mixture has separated into solid by-product and liquid. Once this step has completed, the liquid has passed through a purifying ethanol stage in 5 hours. After that, ethanol fuel is canned and trucked to the gas station to finish the process.
