Abstract
AbstractLosses of volatile acetates have been measured in the vicinity of pressure nozzles during spraying of sucrose and maltodextrin solutions. Large losses occur very near the atomizer, where only a small portion of the water has evaporated. The effects of atomizer design, nozzle pressure, sucrose concentration, air flow rate, air temperature and liquid feed temperature have all been measured. Correlation of volatiles loss vs. percent water evaporation accounts for most of the effects of changes in spray pattern and drop size distribution. Individual contributions of gas and liquid phase mass transfer are determined from the relative retentions of acetates of different molecular weight and from the effect of sucrose concentration. In the expanding film at the nozzle, both gas and liquid phase resistances are important, but the losses become entirely liquid phase controlled once drops are formed.
