Abstract

A method for continuous fermentation in which the carbohydrate solution is fed continuously into the fermentation zone with homogeneous dispersed carbohydrate solutions and yasts. Carbohydrates are fermented into ethanol. Part of the liquid continuously flows through the separator tank under pressure. Liquid with yast drop is pulled from the top of the knit, separates it. The additional yeast-containing liquid was removed from the bottom of the tank and returned to the fermentation zone. Part of the yeast was removed without being brought back into the fermentation zone. The proportions were so large that the yeast concentration in the fermentation zone was constant. And the pressure inside the septic tank is sufficient to prevent the generation of carbon dioxide gas. The encapsulation method allows for a fast, continuous fermentation using a high concentration of yeast. The machine for performing this method has been described.
