The provided diagram illustrates the various stages involved in the industrial production of ethanol fuel using corn as the primary raw material. Overall, the process is linear and comprises nine distinct steps, beginning with the preparation of raw corn and concluding with the distribution of the final fuel product.
Initially, corn is stored and then milled before being cooked for four hours with the addition of water. Following this, the mixture undergoes a fermentation process, which is the most time-consuming stage, lasting 48 hours. Once fermented, the substance is separated into a solid by-product and a liquid component.
In the subsequent phase, the liquid is directed to a purification stage, which requires five hours to complete. After the ethanol has been purified, it is stored in a designated facility. The final stage of the operation involves the transportation of the ethanol fuel to its intended destination. Throughout this sequence, the process transforms raw agricultural input into a refined energy source, with specific time allocations noted for the cooking, fermentation, and purification phases, ensuring the efficiency of the ethanol manufacturing cycle.
