Spray Drying (logo filling)


  • Suspension solids concentration too high Decrease suspension solids concentration (if possible)
  • Atomization air pressure too high Decrease atomization air pressure
  • Drying air temperature too high Decrease drying air temperature
  • Spray guns too far from tablet bed Decrease gun-to-bed distance
  • Poor spray gun design or maintenance Replace or service gun
  • Turbulent airflow Minimize pan negative pressure
  • Aeration of coating suspension Optimize suspension preparation to avoid aeration
