The provided diagram illustrates the industrial method for manufacturing ethanol fuel, beginning with corn as the raw material and concluding with its storage and distribution.
Overall, the production process is linear and comprises eight main stages. It starts with the initial preparation of the corn and moves through several processing steps before the final fuel product is ready for transport.
Initially, corn is subjected to milling, which grinds it into a fine powder. Following this, the milled corn undergoes cooking, during which water is added to create a mash. This mash then proceeds to the fermentation stage, where it is converted into ethanol.
Once fermentation is complete, the mixture goes through separation to isolate the ethanol. This is followed by a purification stage to ensure the fuel meets quality standards. Finally, the purified ethanol is moved to storage facilities and subsequently transported for use.
