Quality of alcohol produced from grains is far better than molasses alcohol and thus fetches higher price. Corn or Sorghum crop cultivation period is about four months and requires comparatively very less irrigation water. New Corn and Sorghum varieties with higher starch content and better yield per acre are also available and, therefore MGDPL use corn and / or sorghum for alcohol production in its distillery.
The net energy value of corn ethanol has been rising due to technological advances in ethanol conversion and increased efficiency in farm production. Corn ethanol is energy efficient as indicated by an energy output:input ratio of 1.34, which means that the energy potential in every liter of ethanol is 34 percent greater than the energy used to produce it.
MGDPL will crush about 80 MT of grains per day in the traditional dry milling process. The milled grain floor will be further subjected to enzymatic liquefaction followed by jet cooking to partly hydrolyze the starch. This slurry will then be further subjected to presaccharifiction with second enzyme and the monosaccharide thus liberated will be fermented with yeast to alcohol. Alcohol present in the fermented mash will then be recovered by distillation. CO 2 produced in the fermentation can be processed to produce food grade compressed CO 2 or dry ice.
This project is envisaged to manufacture following products employing starch hydrolysis, fermentation, distillation and other allied processes. |
