The diagram below shows how ethanol fuel is produced from corn

The diagram details the different steps needed to produce ethanol fuel from corn.
A closer look at the process highlights 9 main steps, beginning with finding corn from producers, and ending with transporting products.
The whole ethanol fuel production process starts when corn are prepared as the main materials. Following this, it will be stored before starting milling. Once this particular stage in the process has been completed, water will be mixed then milled corn are cooked for 4 hours before going to the next step that is fermenting about 48 hours.
After that, it will be divided into two seperate materials including liquid and sold by-products. Next, both of these are put together before going to purify enthanol stafe for 5 hours. Subsiquently, produced corn will be stored again to prepare for transporting in the final step.
