The diagram below shows how ethanol fuel is produced from corn

The picture depicts the production of

ethanol

fuel from

corn

.

Overall

, it can be clearly seen that

this

is a production process, which includes nine steps. The diagram begins with the harvesting of

corn

and ends with the delivery of the products. Looking at the process for more detail, the

corn

is harvested as the first step and

then

stored in a warehouse for preservation prior to milling. During the milling stage, the milled

corn

undergoes the mixing step with an appropriate amount of water.

This

mixture is

then

cooked for exactly four hours. From the rest of the picture, the mixture is left to ferment for two days. A

further

process takes place when the

ethanol

liquid is separated from the fermentation mixture, during which some solid by-products are removed.

Subsequently

, it takes five hours for the

ethanol

obtained to be purified to remove all impurities. Coming to the final step, the

ethanol

is stored before being delivered to the place where it is sold to the market.
