Performance of Cone Type Tower Fermentor for Ethanol Production

탑형발효기에 의한 에탄올 생산

A cone type of tower fermentor loaded with flocculating Sacchromyces uvarum was used to study the fermentor performance. The performance of cone type fermentor was compared with those of other fermentors. The maximum yeast concentration in the cone type of tower fermentor was 35.9-43.0g/1.hr and the maximum ethanol productivity was 14.75g/1.hr at the dilution rate 0.26 $hr^{-1}$. The ethanol yield was 0.446-0.472g ETOH/g Glucose. It was concluded that a cone type of tower fermentor might offer better perspectives for continous etanol fermentation.
