摘要
A prototype of an inclined parallel plate sedimenter was tested for continuous separation of yeast cells (Saccharomyces cerevisiae) from alcoholic fermentation media. For overflow rates in the range of 15 to 30 ml/min, it was possible to obtain a stable flow of the clarified effluent with average cell contents of 0.2 to 1.0% and residence times of 17 to 77 minutes. Thus, the feasibility of the exclusive utilization of a gravitational sedimenter for cellular recycling in continuous alcoholic fermentation, with an efficiency equivalent to much more sophisticated and expensive systems. was demonstrated.
