%X The W/O corn oil emulsion is prepared by high electrical voltage electrostatic spray method.In the working ranges of flow rate of 2.8～15 mL/min and applied voltage of -5.2～-11 kV,the dispersed droplet diameters of prepared emulsion are measured using Winner99 particle image analyzer.The results show that the dispersed droplet size distribution of the emulsion prepared by electrostatic spray method is narrower than that of the emulsion prepared by stirring method.Under experimental conditions,the W/O emulsion with an average droplet size of 28 μm and a size distribution range of nearly 20～40 μm is obtained.The stability of emulsion prepared by electrostatic spray is obviously better than that by stirring method.The applied electrical voltage and spray flow rate have significant effects on the size and size distribution of emulsion droplets.With the increase of the voltage,the droplets become fine in size and uniform in size distribution.With the increase of flow rate,the spraying electrical current increases due to more charge transferred by droplets in unit time,whilst the charge density on droplets decreases,this eventually leads to enlargement of droplet size and broadening of droplet diameter distribution.Higher voltage and smaller flow rate will be helpful to obtain the emulsion with better stability.
