The diagram depicts the stages of ethanol production from corn, commencing with corn harvesting and ending with distribution to gas stations.
Overall, this is a linear, multi-stage procedure that involves major steps: harvesting, storing, milling, cooking, fermenting, separating, purifying, storing, and distributing.
Initially, corn is harvested then brought to factories for storage. Then, the crop is milled, which is later transported on a conveyor belt. Subsequently, water is added into the corn then cooked for four hours using a system of devices. Once that is done, the cooked substance is fermented for a total of 48 hours, which bolsters the quality of the material. The corn is later separated into two contents, where the liquid is kept and the solid by-product is discarded. Afterwards, the liquid is brought to another site, where it purifies ethanol for five hours. Ultimately, the fuel is stored in trucks, ready to be distributed to gas stations. From there, customers can purchase and fuel their vehicles for usage.
