Abstract
A method for pre-clarification of molasses to improve the fermentation efficiency of the molasses and reduce a proportion of the cations in the molasses. The method improves fermentation performance for ethanol production using Saccharomyces cerevisiae. The pre-clarified molasses in accordance with the present invention showed a 2.64% increase in fermentation efficiency.
Claims5
A method for pre-clarification of molasses to improve the fermentation efficiency thereof, the method comprising the steps of:
- diluting the molasses with water in the range of 35 to 40° Brix;
- charging the diluted molasses to a reactor and heating the diluted molasses until temperature reaches 80° C.;
- carbonating the molasses by purging CO2 gas for a predefined period of time at a predefined rate;
- adding polyelectrolyte to the carbonated molasses;
- cooling the polyelectrolyte treated molasses up to 32° C. and settling for 30-100 min;
- diluting the cooled molasses by adding water in the range of 25-30° Brix;
- and
- inoculating the cooled molasses with 5-20% inoculum mixture for fermentation.
