Air-assisted Electrostatic Sprayer (aaess)
Project Description :

In the process of sustainable agricultural development, pesticides have become as a plant protection agent from many dreadful diseases and insects, for boosting food production to fulfill the basic human needs. almost all the protective pesticides are water based and used as sprays. the pedestal-mounted sprayers, the high pressure spray guns, the hand pressure swirl nozzles and the consecutive high volume spraying are still used in agriculture. the use of pesticides should be performed efficiently and effectively to increase the bio-efficacy, since its application without the appropriate technology and technique can cause contamination of the soil and environment, leaving residues in food and increase the risk of poisoning of farm workers health hazards. appropriate formulation design has been instrumental in bringing about significant improvements in the efficiency of pesticide use. yet there is considerable scope for improvements if the technology challenges can be met. the pedestal-mounted sprayers, the high pressure spray guns, the hand pressure swirl nozzles and the consecutive high volume spraying are still used in agriculture. the use of pesticides should be performed efficiently and effectively to increase the bio-efficacy since its application without the appropriate technology and technique can cause contamination of the soil and environment, leaving residues in food and increase the risk of poisoning of farm workers health hazards. there is a pressing need for new chemical application sprayer in indian agricultural pesticides spraying. a new air-assisted electrostatic nozzle has been designed and developed for small scale farms with a specific focus on indian agricultural and geographical scenario. this nozzle is light weight, highly efficient, reduces pesticide use and human health risks, and eco-friendly. an air-assisted electrostatic nozzle is a combination of an air-assisted nozzle and induction based electrostatic charging system. the technique adopted is based on columbic forces between spray liquid and target plant by applying charge on the droplets; it is handy and safe to use as the induction method was used for charging the output droplets. it covers all the liquid based pesticides with full charging efficiency. it is a good technological innovation in the field of agricultural pesticides spraying. the electrostatic force field application to agricultural spraying, one of the most promising methods to apply the protective liquid based sprays onto the biological surfaces of living crops and orchards, has revolutionized the agricultural pesticide spraying techniques by making advances and developments via off-target pest control to increase the deposition efficiency and surface bio-efficacy. electrostatic spray technology has a cut above performance in getting better droplet size, size distribution, deposition rate, uniformity. it increases transfer efficiency, bio-efficacy, uniform deposition, maximum canopy coverage and reaches the hidden areas underneath of the target. the performance of electrostatic nozzle has been evaluated with optimum position of charging electrode and electrical conductivity of liquid, even fraction of differences in electrode position can change the performance of spraying system significantly. typically, spray droplets are electrified to more than 10 mc/kg charge to mass level by charging voltage less than 2.0 kv and electric power consumption less than 75 mw. the deposition of liquid was enhanced 2-3 fold with electrostatic application under the same conditions with non-electrostatic nozzle. this sprayer, light weighted, highly efficient, reduces pesticide use and human health risks, and is friendly to the environment. the unit is ready for the deployment in field conditions and end user level.
