Build-up may be due to dryer configuration, use of wider spray angles and powder formulation, but in many cases, it’s the nozzle design. Product build-up drips on the chamber and becomes scorched particle deposits that compromise powder quality.
Solution: Flat Cap Profile
Click&DryTM flat cap design provides a lower outer face profile that greatly reduces build-up. Click&DryTM technology produce powders with 20% less build-up than any other spray dry nozzle. This is achieved by moving the O-rings into the disc orifice.
Cause of Problem: Wear Part Misalignments
Traditional nozzle designs have misalignments between swirl chamber and orifice. Decentralised parts create inconsistent spray performance and affect the powder quality through all drying operations.
Solution: Concentric Clasp Technology
Click&Dry™ nozzles align wear parts to produce a uniform spray pattern across all lance sets. Achieving a better performance and powder consistency. Pressure – flow is consistent – outcome predictable
2. Low Productivity
Cause of Problem: Nozzle Bearding
Bearding may be due to dryer configuration, use of wider spray angles and powder formulation, but it is mostly due to deficient nozzle design. This increases the cleaning frequency, which delays production. Stopping production for cleaning and short run times plays a big part in dryers’ low productivity.
Solution: Flat Cap Profile
Click&Dry flat cap design provides a lower outer face profile, which greatly reduces bearding. This means fewer dryers shut down for clean-up and, therefore, higher productivity. If we reduce build-up, we slow the bearding process and then nozzles can run longer. The Click&Dry system offers longer run times. Moving the O-rings into the wear part helps achieve this result.
Cleaning traditional spray nozzles is difficult due to the o-ring groove inside the cap. Conventional cap chamber designs have tight and out-of-reach corners that harbour unreachable contaminants.
Solution: Hygiene and Clean Easy Nozzle
Click&Dry™ caps are designed to be easy to clean and produce higher hygienic results. With a smooth internal profile, the spray dry industry can now reach the new level of hygiene with increased ease. Click&Dry™ Smooth bore design improves cleaning and hygiene.
Cause of Problem: Thread Damage and Unprotected Sealing Faces
Ordinary thread systems are too fine to resist normal impact damage. Additionally, unprotected sealing faces can be easily damaged during handling, resulting in cutting and re-welding nozzle bodies.
Solution: Heavy Duty Threads and Robust Cap Protection Skirts
Click&Dry™ nozzles were designed with heavy-duty threads with a special form that is highly resistant to normal impact damage during lance handling. Click&Dry™ nozzles also come with a seal face protection skirt. This robust cap protection skirt is designed for protection against o-ring seal groove damage.
5. Safety Issues
Cause of Problem: Radial o-ring tearing due to assembly
Conventional radial seal systems can suffer from o-ring drag and tearing during assembly, compromising critical sealing.
