The provided flowchart illustrates the multi-stage process of manufacturing ethanol fuel, beginning with the raw material corn and culminating in its final distribution.
This mainly linear process consists of nine stages that altogether unlock the production of ethanol fuel from corn, in approximately 57 hours, with the production of solid by-products that are extracted during the separation process stage.
For this production to begin, the corn is first stored until eventually being milled. Adding water to this previously milled corn enables the cooking of this mixture. After 4 hours of cooking it, the mixture rests for 48 hours, letting the fermenting process occur.
In order to get the solid by-product out of the already fermented mixture, a separation process proceeds, leaving only the liquid and excluding the solid by-product. Subsequently, this liquid enters a 5-hour-long purifying stage. Once this stage is completed, the pure ethanol is stored and eventually transported in the ninth and final stage of this process.
