Process Principles
|
|
| |
|
| |
| |
In solid processes, various individual products of different density and
concentration and in different amounts are often admixed to form a homogeneous
mixture. ( -> Container Blending)
In
the pharmaceutical area, very different quantities and proportions of active and
auxiliary ingredients (corn starch, lactose, PVP, etc.) are mixed
together.
Specific auxilliary materials such as lubricants or flavourings may
also be added.
Mixing may be necessary in different process sections. For
instance, compression aids, flow controlling media and external phases are added
following the granulation process and before compression.

Different blending optionsFor this process, Glatt offers drum and container blenders for container
sizes from 10l to 3000l/batch.
Blending processes can also be carried out before the process step Agglomeration/Granulation directly in the
vertical granulator or in the fluid bed system.
