Drying is the important processes in industrial processes and optimization of drying condition can be save time, costs also reduce energy consumption. In this study drying rate of poly(vinyl acetate) latex film under high electric field has been investigated. Experiments were carried out inside the wind tunnel equipped with controllable temperature and air flow rate. Direct electric field with positive and negative polarity between two types of needle electrodes and an electrode plate was applied with different distances. Applied electric field by forming the plasma around the needle electrode caused to ionic wind and by collision to surface polymer latex and creation of turbulence in saturated layer, increased drying rate significantly. The greatest effect was observed in absence of axial air flow. Drying rate in the first stage of drying under 20 kV was 7 times more than that in absence of electric field. Results also showed that by increasing in number of needle electrodes and reduction in distance of the needle and plate electrodes, enhance the drying rate. But changes in polarity did not affect the evaporation rate. To investigate the interactions between the effect of parameters (weight of polymer, air velocity, temperature and voltage) and modeling of the drying process, design expert software was used. Also quality of dried polymer films in presence of high electric field investigated by scanning electron microscope (SEM) and infrared analysis spectrum (IR).
