The flow chart illustrates the process of making ethanol fuel from corn.
Overall, the process consists of 9 stages, beginning with corn, the raw material ready for processing, and ending with the transportation of the finished product to the customer.
First, the corn at the processing plant is stored, ready for the next stage, which is milling to break down the corn. After the corn has been milled, water is added. The corn is then cooked in the water for 4 hours. Following cooking, the corn is left to ferment for 48 hours.
After this period of fermentation, the next step is the separation of the corn into a solid by-product and a liquid. The liquid then enters the stage of purification to produce ethanol which is completely pure, a process which takes 5 hours. In the final stages of the process, the ethanol is stored, prior to transportation to the customer.
