PROCESS FOR CONTINUOUS ALCOHOLIC FERMENTATION USING IMMOBILIZED YEAST

摘要

PURPOSE:To maintain the alcoholic fermentation characteristics of yeast, stably for a long period, in the production of alcohol using fermentation tanks connected in series and filled with immobilized yeast, by changing successively the paths of the sugar syrup used as a raw material. CONSTITUTION:n-Sets of ferrmentation tanks each containing immobilized yeast obtained by immobilizing a yeast having alcoholic fermentation capability to a carrier are arranged in series, and alcohol is produced by passing the raw sugar syrup from the first fermentation tank, successively to the second,... (n-1)th, and the n-th fermentation tank. Thereafter, the flow of the sugar syrup is changed, i.e. from the n-th tank successively to the 1st, 2nd,... (n-th) tank. After the production of alcohol for a proper interval, th raw sugar syrup is introduced to the (n-1)th tank. According to the above rule, the path of the sugar syrup is changed successively to enable the continuous production of alcohol.
