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

The diagram illustrates several steps of how the manufacture of ethanol fuel from corn is carried out in the factory.

It is clear that

there are 8 main stages in

this

process, beginning with collecting corn from the crops and ending with the resulting product as ethanol is delivered to various gas stations. As can be seen, during the first stage, corn is harvested and kept in storage before being conveyed to a machine in order to be milled.

Next,

water is added and the mixture is cooked for 4 hours. The combination

then

undergoes a fermentation process for 2 days to separate the liquid and solid by-products.

Subsequently

, raw liquor is purified carefully to eliminate all the left substances,

this

procedure takes about 5 hours to be conducted. Once the purification is done, finished ethanol is stored and transported to different gas stations by lorries to provide fuel for vehicles.
