The diagram illustrates the process of ethanol production from corn, detailing each stage involved in this transformation.
Overall,the process encompasses nine distinct steps, commencing with the storage of corn and culminating in the purification and transportation of ethanol.
In detail, harvested corn is stored before proceeding to milling. The milled corn is subsequently cooked with water for four hours, facilitating the preparation for fermentation. This fermentation stage, lasting 48 hours, results in the separation of the mixture into liquid and solid by-products. The liquid component undergoes a purification process lasting five hours to extract ethanol, which is the desired product.
After purification, the ethanol is stored before it is transported. Notably, the process highlights the significant time allocated to fermentation, accounting for the majority of the production period, while cooking and purification are relatively brief in comparison. This structured production method emphasizes the efficiency of converting corn into ethanol fuel.
