Alternative to tank cleaning spray ball

23 January 2017

Because traditional spray balls are static the majority of the tank cleaning energy comes from water cascading down the tank wall and requires large amounts of time, water and energy to compensate for poor cleaning performance. Compared to a static spray ball, the Alfa Laval Rotary Jet Head is said to offer a lower operating cost giving a short payback time - often less than a year. 

Its design ensures that the first – of eight – cleaning cycles hits the tank wall at an evenly dense cleaning pattern throughout the tank surface. The distance between the footprint tracks is relatively wide, but if the product is easy to clean off (for example milk or syrup) it requires little wall shear stress to be removed. This means the pre-rinse cleaning of the tank is done using only one cleaning cycle saving time, water and energy.

When the water jet, coming from a rotary jet head cleaning device, hits the tank wall, it generates a force of impact (N). After impact, the jet spreads out and creates a cleaning footprint with high wall sheer stress force (Pa). As the cleaning machine is rotating in a 3D motion, the footprint is moving around inside the tank in a predefined pattern cleaning the entire tank surface with high wall shear stress. The further away from the impact point the less wall shear stress (mechanical action) is achieved.

One cleaning cycle typically takes between 1-3 minutes and now the product is effectively removed from the tank wall, the jet will offset the second cleaning cycle, minimising the distances between the jets. More cleaning cycles are needed for products that are harder to clean.
