Patent ID: 7862992

Claim:
A method for the production of ethanol comprising: receiving a temperature of a simultaneous saccharification and fermentation system; receiving a pH of the simultaneous saccharification and fermentation system; receiving information identifying amounts of components of a fermented mash generated by the simultaneous saccharification and fermentation system; generating, based at least in part on the temperature, the pH, and the information identifying amounts of components of the fermented mash, values for temperature, pH, and enzyme dosage for the simultaneous saccharification and fermentation system; and outputting the values to one or more controllers of the simultaneous saccharification and fermentation system wherein the generating and outputting values are based at least in part on a saccharification model that predicts concentrations of fermented mash or a fermentation model that predicts yeast metabolism, the one or more controllers allowing for the production of ethanol.
