LINDAL unveils new technology for spray performance insight
Aerosol dispensing company LINDAL Group has introduced an advanced spray imaging system to help deliver new levels of spray performance insight for customers.
LINDAL already conducts spray analysis in the form of flow, particle size, spray angle and shape, and spray pattern performance on its standard product range, as well as bespoke solutions developed with its innovation partners.
This new technology not only adds to this but provides a new avenue for in-depth consumer tests, with additional spray characterisations, including the measurement of shape and velocity, also planned for the future utilisation of the technology.
Deployed at LINDAL’s Global Innovation Centre (GIC) in France, the technology uses optical techniques to capture spray behaviour at high speed (around 7,500 images per second). Comprising of front and back radial lighting, camera and suction system hardware, its integrated software produces 30-second videos of spray movement for analysis, equivalent to 0.1 seconds in real-time.
The process provides detailed information on axial plume spray, including the particle distribution, as well as the angle, diameter and length.
“The software’s ability to capture the behaviour of the spray and not simply the size of spray particles, is crucial,” said Eric Lambine, central laboratory manager at LINDAL’s GIC.
“This information allows us to understand so much more about spray patterns and performance, which creates far greater objectivity to our analyses and discussions. We believe it will significantly benefit our customers that we are working with now and in the future.”
LINDAL also believes the spray imaging system will be effective when testing compressed air dispensing solutions. Spray performance can be affected due to a reduction of pressure over the lifecycle of the can, resulting in larger droplet sizes and a ‘wet’ final product, not suitable for hairsprays and deodorants, for example.
“We aim to generate a template incorporating an optimum propellant, valve, and actuator combination, as well as deriving further quantitative data, producing new levels of quality in all our dispensing systems,” added Lambine.
“Our ultimate goal is to give our customers the best opportunity to provide an improved consumer experience.”
