A newly-developed cascade feed technique using two reactors was applied to the continuous production of a high ethanol solution. Ethanol solution more than 15 vol% was continuously produced for about 50 days. Simulations of the cascade feed technique with the two reactors were carried out, using mathematical equations which approximated the actual distribution of glucose and ethanol in an immobilized yeast bioreactor. The simulated results showed that the first reactor should be operated so as to assimilate most of the charged glucose.
