Process Principles  

 
 

 

  Spray granulation is the drying of liquids (solutions, suspensions, melts) while simultaneously building up granulates.
Germs can be provided for granulates (foreign germs) or can form in the fluid bed due to abrasion and fracture (inherent germs). The spray liquid coats the germs and is then dried.
Spray granulates are denser and harder in comparison with agglomerates.

(-> Fluid Bed Granulation/Spray Granulation)
For particles difficult to fluidize we have developed the Glatt Spouted Bed Technology.
