5. Properties of Powder
Definition: A pharmaceutical powder is a mixture of finely divided particle of drugs or
excipients in dry form.
• Particle Size:
Difference in size >> efficient packing via interlocking effects
Particle Size Distribution (PSD) in a powder sample
Affects powder bulk flow
Small size particles Vs. large size particles
• Particle solubility
Affects drugs disintegration and dissolving
• Particle Shape
Isometric: round shape >> best for hard capsule
Anisometric: needle-shaped >> different particle orientation >> irregular fluidity
• Particle Adhesion
Dissimilar particles stick to one another to surfaces.
Therefore, substances break powder uniformity
• Particle wettability
Critical to drug substance release
• Flowability
Ability of powder to flow in an equipment.
Depends on physical properties of powder and the used equipment
i.e. bulk density, friction permeability, forces, porosity.

9. Hard Capsule filling
• Tamp filling system into capsule size one
• Dosator nozzle system into capsule size zero
• Powder in dosator nozzle can be calculated
10. Tamping filling machine
• Three different bed heights used
• Pin setting tested for each bed height and
ranged from no compression to firm
compression
11. Tamping filling machine
Cont’
• Acceptable filling can be achieved and
independent of type of machine
• Tamp filling better for coarser granules
and no solid plug can be formed
• Dosator nozzle filling machine- plug
formed but denser than maximum bulk
density

14. Soft Shell Capsule Processes
Accogel process- process for manufacturing of soft gels with
powders or granules
Measuring roll rotate directly over the die roll and
pockets in the 2 rolls are aligned
Measuring roll powder or granular fill material
under vacuum
Die roll plasticized sheet under vacuum
Sealing roll second gelatin sheet applied to form
other half of capsule
Pressure developed between die roll and sealing
roll seals and cuts out the capsules
Drying process
Capsule need to be dried hard for packaging.
Tumble dryer used for soft capsule about 30 to 40
min remove 25%
transferred to drying room and it takes about 24-
48 hours
