4.OPACIFIER:
Used in shell has to be darker than colour of encapsulating material colours may be natural or synthetic. 4.OPACIFIER: Usually titanium dioxide, may be added to produce an opaque shell ,when the fill formulation is a suspension or to prevent photo degradation of light sensitive fill ingredients. Concentration of opacifier may be up to 0.5% 5.Chelating Agents:
Iron is always present in raw gelatin, & should not contain iron more than 15 ppm. Additionally chelating agent may be used for preventing the reaction of iron with materials or colours.

Plate Process
Plate Process A warm sheet of gelatin is placed on the bottom plate of the mold. The liquid medication is poured on it. Then the second sheet of the prepared gelatin is carefully laid in place on top of the medication,and the top plate of the mold is put in place. The entire mold is then subjected to a press where pressure is applied to form fill and seal the capsules simultaneously. Then the capsule is removed.
Rotary Die process
Rotary Die process Rotary machine In rotary die machine ,the soft gelatin capsules are prepared and then filled immediately with the liquid medicaments.
Rotary die press:
Rotary die press: In this process, the die cavities are machined into the outer surface of the two rollers. Gelatin is properly weighed & dispensed in melting tank under vacuum of 93ºc. Two plasticized gelatin ribbons are continuously and simultaneously fed with the liquid or paste fill between the rollers of the rotary die mechanism.
As the die rolls rotate, the convergence of the matching die pockets seals and cuts out the filled capsules.
Accogel Capsule Machine:
Accogel Capsule Machine: It consists of mainly 3 parts: Measuring roll Sealing roll As the measuring roll and die rolls rotate, the measured doses are transferred to the gelatin-linked pockets of the die roll. The continued rotation of the filled die converges with the rotating sealing roll where a second gelatin sheet is applied to form the other half of the capsule.
Pressure developed between the die roll and sealing roll seals and cuts out the capsules.
