cretical point in granulation section
how to calculate capacity of RMG and FBD
Critical point in Wet granulation are:
- Binder addition time
- Kneading time
3.Impeller and chopper mixing Time and RPM
4.Impeller power (Ampearage reading-End point estimation)
5.Total granulation Time
Mr asifvexpkaind well in addition
Wet mill speed
dry sieving particle size
lubrication mixing time is very critical n b 3 -5 min
sir it is necessary to use separate filter bags for each product in drier of wet mixer???
In advanve FBDs SS filters are fitted wich are washed after product changeover.
In conventional FBD where fingr bag is used it is difficult to manage 200 filterbags if u hav 200 products.
So filter are are used acordingc to drug classes e.g
general products,quinolones,psychotrophic etc.
Frequency of filter bag change is determined by validating the processes n bag condition.e.g 3 mnth ,6 mnth 1 yrs etc
Its is not neceessery to use seprate Bags for each product.
