The diagram illustrates the process of producing ethanol fuel from corn.
Overall, it is a linear process consisting of several stages, starting from storing corn and ending with transporting the final product. Notably, fermentation and purification are key stages in this procedure.
Firstly, corn is stored and then milled to produce smaller particles. After that, water is added and the mixture is cooked for about four hours. Following this, the cooked mixture is left to ferment for 48 hours.
Next, the fermented material is separated into two parts: a solid product and a liquid. The liquid part is then purified for five hours to produce ethanol fuel. Finally, the ethanol is stored and transported to its destination.
