The Process of Industrial Alcohol Production

A primary industrial alcohol is ethanol, or ethyl alcohol (C2H5OH). The process of alcoholic fermentation is one of the oldest processes and is known as the most important of the industrial fermentations. The alcohol fermentation process has ethyl alcohol being produced from carbohydrate materials by the addition of yeasts. The process is extra cellular. 
The yeasts have an ability to convert sugars into alcohol and in the process; there is also a production of other end products which are of great value. These products are used by brewers, bakers and distillers, chemical manufacturers and wine makers etc.

The manufacture of Ethyl Alcohol is done using the raw materials as well as the Micro-organisms used. The process involves several steps that include:

Raw Materials: Molasses is one of the commonly used raw materials in the industrial alcohol production. Molasses is also available at a low cost and is very easily available.     

Micro-organisms: Yeast Saccharomyces cerevisiae are commonly used for fermentation. The reasons for their use are their rigorous growth, their tolerance for alcohol and their capacity for producing a high yield of alcohol. 

The other kinds of media which is put into use for the alcohol production includes the black strap molasses, grains, Whey, Potatoes, Sulfite waste liquor and also some wood wastes. 

Steps involved in the process     

The industrial alcohol production can be termed as a large scale biotechnological process which requires large scale tubular tower fermenters (bio-reactors) and involves the following steps:
