The diagram illustrates the production of ethanol fuel from corn.

The given picture illustrates shows information about the steps and equipment involved in the process of making ethanol fuel from

corn

. As can be clearly seen from the image, the process has multiple different stages starting from harvesting the

corn

and ending with the delivery

stage

. Looking at the picture more closely, one can see that,

firstly

stage

,

corn

is harvested and

then

stored in a suitable place to ensure safe storage before it is ready for milling. During the milling

stage

,

corn

is crushed into powder and mixed with water.

The next step is

workers will cook them for four hours.

After

this

stage

is complete, the fermentation comes and lasts for 48 hours to turn

corn

and water into an alcoholic mixture. After that, the liquid ethanol is separated from the fermented mixture, during which some solid by-products are taken out. That liquid is

then

purified within 5 hours to get rid of water for an extraction of pure ethanol, which is

then

transferred to fuel storage. Once the final step has been completed being transported to retailers, ready to be sold.
