Capsules Flashcards
Schematic filing of hard gelatine capsules
1) Concentration of gelatin prepared in hot demineralised water
2) Pins mounted on metal pars are dipped in gelatin solution
3) Removed with a film of gelatin
- rotated
- passed through drying kins
- stripped of pins and cut to size
- two halves are joined together
Powder filling : Dependent
Uses the capsule body directly to measure the powder
- slow
- dependent on operating skills and uniformity of dosing
- dependent on powder flow and uniformity of filling
Powder filling : Independent
A plug of material is formed which is transferred to body dose is determined by volume of plug in dosator adjusted by the moving position of the piston
- Uses a dosator
- Tube containg a variable volume chamber at the bottom and piston at the top
- Used in large scale
Powder filling of hard gelatine capsules
Diluents - Aids flow and compression
Glidents - Decrease interparticulate adhesion
Lubricants - Decreased adhesion to metals
