Axial Flow Blower for Air Assisted Orchard Sprayer

Uniform distribution and deposition of chemical from top to bottom of plant canopy and on the undersides of leaves is of utmost importance for effective pest control. Incorporation of air assistance in spraying system improves the deposition uniformly in the entire tree canopy. Spray deposition on the lower portion of plant leaves, where most of pests harbor, also improves in the air assisted spray application . The deposition of spray droplets, requirement of air volume in air assisted spraying system and pesticide application rates are mainly influenced by canopy characteristics like leaf area index and leaf area density. The higher leaf area density results in lower droplets density at the canopy. The tractor operated air-assisted sprayer in which high air velocity is generated through axial or centrifugal blower produces smaller size droplets . The air-assisted sprayer produces appropriate size droplets uniformly reducing losses of expensive chemical and environmental pollution. The fine droplets at high pressure during movement mix up thoroughly with air.
