The illustration highlights the various stages involved in the process of making ethanol fuel from corn.
Overall, it can be seen that the process is divided into nine stages, which are corn harvested and transported. In total, there are several steps in the process, commencing with harvesting the corn and culminating with the distribution of end products.
In the first stage of the process, the corn is harvested, which undergoes storing before being milled with water. Then, the resulting mixture is cooked for four hours by fire power. After cooking, the mixture undergoes a fermentation process, which takes two days and the ethanol is produced after this stage. In the next stage, the liquid ethanol is separated from the fermented mixture, during which some solid by-product is taken out. After that, it takes about five hours for the resulting ethanol to be purified to remove any impurities before being stored. Finally, this ethanol is packaged, they are transported to retailers, ready to be sold.
