The flowchart illustrates an overview of the steps involved in generating ethanol fuel from corn.
Overall, the process consists of eight main stages, starting with the cultivation of corn, followed by the separation into liquid and solid by-products, and ending with the distribution of ethanol fuel to gas stations.
Initially, corn crops are harvested manually and stored in containers. The corn is then broken in a milling machine in order to become cornmeal. Following that, this cornmeal is cooked with water for four hours, after which this cooked corn undergoes a fermentation process for 48 hours. Over two days, chemical reactions occur so that it can be ready for the separating stage. Once this step is complete, liquids are separated from solids, and then the ethanol is purified for five hours so as to remove impurities.
In the final step, these materials are loaded onto trucks in order to transport them to gas stations for commercial and industrial use.
