| Abstract: | The evaporating characteristics of a dimpled vertical plate falling film evaporator in concentrating termamyl liquid was studied compared with a tubular falling film evaporator The experimental connected formula related to the volumetric flow rate per unit wetted width,enzyme concentration,heat transfer temperature difference and vapor temperature was obtained Some factors effected on the heat transfer coefficient were analysed The results indicated that the heat transfer coefficient in the dimpled vertical plate evaporator was higher than that in the tubular falling film evaporator The dimpled vertical plate evaporator was fit for the evaporation of active material |
