The flowchart illustrates the steps of producing ethanol fuel from corn. Overall, it is a long process that requires many hours of preparation to reach the final product.
The process starts after the harvested corn is stored properly in containers. It will then pass through a milling machine to cut the outer layers. Afterward, it is mixed with water and cooked for four hours. The resulting mixture is fermented for another two days.
This material is machinery separated into liquid and solid substances. After this step, the liquid is purified for 5 hours to remove the impurities. The purified ethanol is then stored and is ready for transportation and usage.
In summary, the diagram explains the eight steps required to transform corn into fuel. Corn is used as the primary raw material, which undergoes several phases of cooking, fermentation, purification, storage, and finally distribution for consumption.
