Powder Processing
Dynamic Dryer
Ultimate form of evolution of one-pot process. High volume air supply to High Speed Mixer. Powerful agitator blades for uniform drying of highly viscous wet
FEATURES
- particles
-
- Pharmaceutical and food
One-pot process involving mixing, granulation, and drying (optimum for multiple-product small-lot production) Mixing and spray granulation - Chemical
Agitation, aeration, and drying of highly viscous paste like and caked product Coating of nuclear particulates
- Pharmaceutical and food
- Advantages
- Drying air is supplied from the tangential direction to avoid disturbing the particle flow induced by agitation. Thus, a smooth flow of particles can be obtained.
- Methods of binder feeding
-
- Drop method
Suitable for rapid granulation, but often resulting in broad particle size distribution - Spray method
Time consuming, but with uniform binder dispersion. Combined use with drying air enables flexible particle designing.
