The diagram shows how ethanol produced from corn

This

graph illustrates the process of producing ethanol fuel which is made of

corn

.

Overall

, there are apparently three main parts, starting with storing and milling, followed by dividing into liquid and solid substances, and

then

the final dealing with transporting.

Firstly

,

corn

is milled after storing it for a period, and

then

is cooked with water. Following on, the

corn

was cooked for 4 hours, and put down for fermenting in 48 hours.

Subsequently

, in the separating stage, it is going to be divided into solid and liquid. The former are by-products, but the latter need more steps to deal with. Next in the 7th process, it can be observed that purifying the liquid of

corn

for generating Ethanol expenses 5 hours.

Following

this

, the

corn

is formed as the ultimate product and stored. Moving forward to the final stages, the completed products of ethanol fuel will be transported to use.
