The diagram illustrates the process of ethanol fuel production from corn. The process consists of several stages, beginning with the storage of corn and concluding with the transportation of the purified ethanol.
Initially, corn is stored before being sent for milling, where it is ground into smaller particles. After this, water is added, and the mixture undergoes a cooking process that lasts for four hours. Once cooked, the mixture is transferred to fermentation tanks, where it remains for 48 hours. During this phase, microorganisms break down the components, leading to the production of ethanol.
Following fermentation, the mixture is subjected to a separation process. At this stage, the solid by-product is removed, while the remaining liquid undergoes further treatment. The extracted liquid is then purified for five hours to obtain pure ethanol. After purification, the ethanol is stored in appropriate facilities before being transported to its final destination.
Overall, the production of ethanol fuel from corn is a systematic and sequential process involving multiple stages, including storage, milling, cooking, fermentation, separation, purification, and distribution. Each step is crucial to ensuring that the final product meets quality standards and is suitable for use as a biofuel.
