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.
