The flow picture illustrates sequantial steps involved in the production of ethanol fuel from corn. Overall, the procedure encompasses several stages, commencing with storing raw ingredients and concluding with the distribution of fresh alcohol for different uses.
To begin with, corn is harvested and carefully stored in some large barns on the farms. It then undergoes a milling process, where it is grounded into smaller particles. Following this, the milled corn is cooked for four hours, with a sufficient amount of water added during the ongoing phase. After cooking, the mixture is left to ferment for another two days under proper observation.
The process continues with the fermented substance being seperated into liquid ethanol component and solid by-products. Next, the liquid goes over the stage of purified, lasting five hours, where fresh ethanol is collected and ensured to reach the adequate level of purity for fuel use. In the final steps, the purified ethanol is stored in containers and tanks before being transported to petroleum stations or other facilities in need.
