Preparation of Gelatin Solution.
After passing the preliminary quality control tests the Gelatin is released for production
Purified water is added in melter and then Gelatin is transferred by vacuum in the melter, and heated at 70 to 76 degrees centigrade until it reaches the correct viscosity, vacuum removes the air bubbles from solution
Here QA checked the viscosity and Temperature of Gelatin solution, Viscosity should be 25 to 27 inch and Temperature 55 to 58 degree centigrade
Color Mixing.
At this point natural Gelatin Solution is transferred in gelatin feed tanks of 80 & 120 Liter capacity and required colors & titanium di oxide is added for opaque and only colors are added for transparent capsules as per formulation of required shade,
Following Test are performed
Color Film preparation, Viscosity & Temperature of solution Gelatin Feed tanks hanged on Capsule manufacturing machine these machines are PLC controlled and capsule profile is programmed in machines, following manufacturing steps occurred
- Dipping: Dipping of pin bars in gelatin solution. after dipping the pin bars are removed and rotated to distribute the gelatin as uniformly as possible around the pins than Gelatin allowed to set.
- Drying of Capsule: Traveling along the conveyor belt, the bars carrying the pins coated with solidifies gelatin pass through a upper and lower kilns until the moisture content is reduced to required level.
- Stripping, cutting and joining of shell: The machine automatically strips the formed Gelatin shells from the pins bars, Cut it to the correct length and join the cap and body in pre – closed position
- Quality Assurance Capsules are hourly analyzed for physical defects, length, dome, Wall thickness, moisture content, weight, color shades other relevant parameters.
