The diagram demonstrates the sequential process by which ethanol fuel is derived from corn.
Overall, the procedure encompasses ten distinct stages, initiating with the storage of corn and culminating in the transportation of the finalized ethanol fuel.
The process commences with the storage of corn, which is subsequently subjected to milling. This milling phase necessitates the addition of water, following which the resultant mixture undergoes cooking for a duration of four hours. This heating phase is crucial for preparing the corn for fermentation. After cooking, the mixture proceeds to the fermentation stage, lasting 48 hours, during which the necessary biochemical reactions occur to convert sugars into ethanol.
Upon completion of fermentation, the subsequent step involves the separation of the mixture into liquid ethanol and solid byproducts. This separation results in two distinct components, which are integral to the production of ethanol. The liquid component is then purified over a five-hour period to enhance its quality. Following purification, the ethanol is stored in readiness for distribution, with the final stage being the transportation of the fuel to its requisite destinations, thereby completing the ethanol production process.
