The diagram below shows how ethanol fuel is produced from corn.

The diagram illustrates the process of producing ethanol from

corn

which

then

was delivered for sale. There are 3 main stages shown in the diagram, beginning with the collection of

corn

from harvesting,

then

culminating with pure ethanol and

finally

ready to be transported and sold. The procedure of producing ethanol from

corn

starts with the collection and storage of

corn

. The

corn

is

then

milled and cooked with water for around 4 hours. Once it has been cooked, it

then

undergoes a progress of fermentation which takes around 48 hours to complete. Afterwards, the fermented product is

then

put through a step which separates the liquid from the solids. The liquid

then

needs to be purified, which takes around 5 hours,

while

the solid material ends up being a useful by-product of the process. After the liquid has been purified, it can

then

be stored before it is shipped to the consumers.
