The diagram illustrates the step-by-step process of producing ethanol fuel from corn. Overall, the procedure involves a series of stages starting from storing corn and ending with transporting the purified ethanol fuel, with both chemical and physical changes taking place during the process.
The process begins with corn being collected and stored. After that, the stored corn undergoes milling, where it is ground into smaller particles. Water is then added during the cooking stage, which lasts for about four hours. Following this, the mixture is transferred into a fermentation tank, where it remains for 48 hours to undergo fermentation.
Once the fermentation process is completed, the mixture is separated into two components: a liquid and a solid by-product. The solid part is removed, while the liquid continues to the next stage. The liquid is then purified for five hours to produce ethanol.
After purification, the ethanol fuel is stored carefully before being transported to different destinations for use.
In summary, ethanol fuel production from corn is a multi-stage process involving physical preparation, chemical fermentation, separation, and purification, ultimately resulting in a usable biofuel.
