The diagram illustrates the process of producing ethanol fuel from corn.
Overall, the ethanol production process involves storing the corn, milling, cooking with water, fermenting for 48 hours, separating into liquid and solid by-product, purifying the liquid into ethanol, and finally storing and transporting the ethanol fuel.
The process starts with harvesting the corn, which is then stored in a suitable place to ensure its quality before further processing.Then milling, which the corn is ground into a fine powder, effectively breaking down the kernels. After that, the milled corn is mixed with water and then cooked for approximately four hours. The cooked mixture is left to ferment for two days.
The following is Separating step, fermented mixture is separated into liquid ethanol and solid by-products. Then, the liquid ethanol is purified for five hours to remove any impurities. The last step, the purified ethanol is then stored for a period of time before being transported to retailers for sale.
