Abstract:
     The invention relates to the method for culturing alcoholic yeast by enzymolysis of starch. The undecanted wine is cooked and strach hydrolysis enzymeis added, and then they are led continuously into an air lift type inner cyclic yeast culturing tower which already has yeast fungus to carry on starch scacharification and yeast culturing dual side fermentation, the ripe wine yeast is taken out continuously from the tower. The whole culturing course uses the breath ratio to control. A culturing tower of 2 liters can produce the ripe yeast 7.5 g.per hr. When the dilution rate D=0.05-0.35 per hr the concentration of fungus reaches 30 g. (dry fungus ) per liter, the production rate of fungus reaches 5 g. per liter per hr. The technological process is simple and stable, activity of the yeast is high.
