Abstract

The paper describes a method for charging spray droplets for pesticide application in agriculture. An induction based electrostatic charging system was developed with optimized parameter namely flow rate, electrode voltage and distance of electrode from nozzle tip. A high voltage charging module was fabricated to supply the voltage up to 10 kV. The experiments were conducted in division of agricultural engineering, IARI, New Delhi during 2017. A faraday cylinder test rig was used to optimize the flow rate, electrode voltage and distance of electrode from nozzle tip. The highest charge to mass of 1.543 mC/kg was obtained at a flow rate of 450 ml/min, applied voltage of 4.0 kV and electrode distance of 40 mm respectively. The results of CMR established the relationship between CMR and selected design parameters. The statistical analysis revealed that the individual effect of selected parameter had significant effect on CMR at 1% level of significance, whereas the interaction effect of voltage, flow rate and electrode position from nozzle tip had no significant effect on CMR.
