The spray-dried or frozen-dried powder of Western medicine or traditional Chinese medical extract is featured by non-uniform size and density, poor fluidity and easy layering. To make up for these shortages, granulation should be included as a key process. Only powder after granulation can be pressed, filled into capsules or packed better.
 
It is learned that dry granulator is the new-generation granulating machine after one-step granulating machine. It is pretty friendly to the environment and thus widely applied in pharmaceutical industry to process especially material which might decompose, lose effect or lump in the circumstance of high moisture or temperature.
 
 
During granulation, the dry powdery material (Western medicine or tradition Chinese medical extract) is mixed and then fed into the cone hopper. The material has certain amount of crystal water. An irregular-shape non-isometric conical auger rotates and feed material downwards. In this step, the auger generates pressure to compress the material, exhaust air and press the powder to sheets. Then the sheets are shredded and granulated in granulating system.
Advantage of dry granulation to compare with wet granulation?

Compared with wet granulation, dry granulation can apparently save energy. Its technique is pretty simple to avoid many challenges of GMP. The machine covers small area and thus the production cost is lower. It can be dismantled and cleaned easily and conveniently. The inner and outer sealing structure can prevent its electric box and driving parts from being damaged and contaminated by water during cleaning.
