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.

Hard Capsule filling

• Tamp filling system into capsule size one
• Dosator nozzle system into capsule size zero
• Powder in dosator nozzle can be calculated
Tamping filling machine

• Three different bed heights used
• Pin setting tested for each bed height and
  ranged from no compression to firm
  compression
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
Tamping filling machine

Disadvantage: the large variety of possible
 machine settings.

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

  • 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
  • 12. Tamping filling machine Disadvantage: the large variety of possible machine settings.

  • 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 http://kinam.com/Lectures/363/3.Capsules %20Text.pdf
