Capsule Manufacturing Process
1. Once raw materials have been received and released by Quality Control, the gelatin and hot demineralized water are mixed under vacuum in R&J Engineering's Stainless Steel Gelatin Melting System. |
2. After aging in stainless steel receiving tanks, the gelatin solution is transferred to stainless steel feed tanks. |
3. Dyes, opacifants, and any needed water are added to the gelatin in the feed tanks to complete the gelatin preparation procedure. The feed tanks are then used to gravity-feed gelatin into the R&J Capsule Machine. |
4. From the feed tank, the gelatin is gravity fed to R&J's specially engineered Dipper section. Here, the capsules are moulded onto stainless steel Pin Bars which are dipped into the gelatin solution. |
5. Once dipped, the Pin Bars rise to the upper deck allowing the cap and body to set on the Pins. |
6. The Pin Bars pass through the upper and lower kilns of R&J Engineering's Capsule Machine Drying System. Here gently moving air which is precisely controlled for volume, temperature, and humidity, removes the exact amount of moisture from the capsule halves. |
7. Precision controls constantly monitor humidity, temperature, and gelatin viscosity throughout the production process. |
8. Once drying is complete, the Pin Bars enter the Table section which positions the capsule halves for stripping from the Pins in the Automatic section. |
9. In the Automatic section, capsule halves are individually stripped from the Pins. |
10. The cap and body lengths are precisely trimmed to a ±0.15 mm tolerance. |
11. The capsule bodies and caps are joined automatically in the joiner blocks. |
12. Finished capsules are pushed onto a conveyer belt which carries them out to a container. |
13. Capsule quality is monitored throughout the production process including size, moisture content, single wall thickness, and colour. |
14. Capsules are sorted and visually inspected on specially designed R&J Inspection Stations. |
15. Perfect capsules are imprinted with the client logo on high-speed capsule printing machines. Capsules are now ready to be sterilized and packaged. |
