Close revision note
RevisedThe process of producing ethanol fuel from corn.
The word 'corns' is not typically used in the plural form in this context. The word 'corn' is generally used in the singular form when referring to the grain used in ethanol production.

The process begins with corn, It gets stored and is then taken to the mill machiene to start the milling process, which helps us use the corn to obtain as much fuel as possible. After the milling process is over, the cooking process begins. Cooking takes about 4 Hours with the use of Water, and is then fermented for the next 48 Hours to help with the seperation of the fermeted corn into Solid and Liquid. The solid parts are thrown and not put into use, as they are not needed for the making of ethanol fuel. After the liquid parts are aquired we start the purification process of ethanol, which takes around 5 hours to complete. After the purification of ethanol, we start storing the ethanol very carefully to ensure no leakage or oxidization occurs during the process of transportation.
