The diagram illustrates the manufacture of ethanol fuel from corn. The process of making this fuel requires 9 steps in total. It begins with harvesting corn and ends with delivering products to the gas station.
The first stage involves collecting corn from fields and then delivered to warehouses to store. After that, corn is milled in the grinder and mix with water to be cooked for 4 hours. The mixture after cooking is fermented in 48 hours.
At the next stage of the process, the combination is separated into liquid and solid by-products, a liquid obtained and then be purified in 5 hours to eliminate bacteria before stored in fuel tanks. Finally, ethanol fuel production ends when the product is loaded into containers and moved to the gas station.
