Our Challenge
At one of our customer’s production site, two spray drying towers producing the same product showed inconsistent performance: one delivered 750 kg of powder per cubic bag, while the other only managed 500 kg. This discrepancy raised efficiency concerns and customer questions.

Our Solution
Our specialist identified the issue: the product from the two towers wasn’t identical, as initially believed. Additionally, one tower operated at an excessively high temperature, causing rapid surface drying of droplets. This resulted in the liquid inside boiling, causing the droplets to burst and form hollow powder particles with low bulk density.

By analyzing the powder under a microscope, the hollow structure was confirmed. We then reduced the drying temperature and tested various nozzle combinations to optimize droplet formation and drying dynamics.  

Results for our customer

• Significant bulk density ensuring consistent bag weight across both towers
  
• Reduced transport costs  
• Improved process efficiency
