The flowchart illustrates the production process of ethanol fuel using corn, detailing various stages from storage to transportation.
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.
At the initial stage, the corn is stored and then transferred to the milling process. Subsequently, the corn is mixed with water and cooked for 4 hours. Following this, the cooked mixture undergoes a 48-hour fermentation process. Once the fermentation is complete, the mixture is separated into liquid (ethanol) and solid by-product. The liquid undergoes a 5-hour purification process to produce ethanol. The solid by-product is considered waste. In the penultimate step, the produced ethanol is stored before being transported to its final destination.
The entire process takes place over specific timeframes, with the longest duration being the fermenting process (48 hours), followed by the purification process (5 hours). The diagram also illustrates that the final product, ethanol fuel, undergoes a separate storing and transporting stage to reach its intended location.
