The picture illustrates the production of ethanol fuel from corn. Overall, there are three main stages in the process of using corn to produce ethanol fuel, beginning with the harvesting of corn and concluding with the transportation of ethanol to gas stations. Additionally, this process relies heavily on machinery and takes a significant amount of time.
The initial step involves harvesting corn, which is then stored for the subsequent stage. After storage, the corn is crushed using a milling machine. The resulting corn powder is cooked for four hours in a mixture with water.
Following the cooking stage, the mixture undergoes fermentation for two days. After fermentation, the mixture is separated into liquid and solid products. The liquid then goes through a purification process, which takes five hours to complete to create the final product.
In the final stage, the purified ethanol is stored and is later transported to gas stations.
