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

The given chart illustrates the

process

of producing ethanol from

corn

.

Overall

, it can be seen that there are approximately 9 steps in the

process

, starting from the collection of

corn

from the field, and culminating with pure ethanol, ready to be transported and sold. The

process

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

process

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

then

put through a

process

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.
