New Technology for the Spray Industry
Kansas State University Biological and Agricultural Engineering Department
Nozzle is still an important part of the application process!
Determines the application rate
Determines the uniformity Determines the coverage Determines the drift potential
Kansas State University Biological and Agricultural Engineering Department
What’s new in nozzle technology? Nozzles designed to reduce drift Improved drop size control
Kansas State University Biological and Agricultural Engineering Department
Air-Induction/Venturi NozzlesWhere air is drawn into the nozzle
cavity and exits with the fluid.

Results and Discussion

Findings for Part #3: DropletScan does appear to be a
software program that will provide quick and useful information regarding drift for various nozzle types.
Data supports that drift potential is less with the venturi nozzles compared to the conventional nozzles.
The collection technique needs to be fine-tuned to make better use of the data collection possibilities.

May be advantages to analyzing the spray droplet at the target site rather than as it leaves the spray tip.
Will measure stains as small as 50 microns.
Good analysis of lower application rates and driftable size fines.
Important to note that:

Important to note that:
Humid/moist conditions currently will not allow system to be effective.
Even though the wind confused the data in this study, wind does have a major affect on deposition and drift and must be factored in for each application scenario.
