The diagram below shows the production of ethanol oil from grain. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

The diagram illustrates the process of producing ethanol oil from

grain

. There are 12 main stages in the manufacturing process, beginning with

grain

being kept in storage and ending with two types of products provided to the feed or fuel market. The first step involves the storage of

grain

in the warehouse,

then

millling and cooking respectively. After that, the

grain

experiences the stage of liquefaction. The solution

that is

the result of

this

stage

then

ferments in the tank with specialized instruments. The fuel ethanol is obtained by experiencing the course of distillation. Fuel ethanol which is a liquid can be put in big cans, after that it directly accesses the energy market.

Whereas

, the residual of the distillation process called “wet distillers

grain

” is dried by means of an electric heater to become the solid substance known as “dry distillers

grain

”.

Finally

, it will come to the feed market as a product catering to nutritional needs.
