Introduction of Softgel Drying Tunnel
Softgel (or soft gelatin) capsules require a controlled secondary drying process to reduce water content in the capsule to levels appropriate for product stability, further treatments including polishing which can be produced by capsule polishing machine, and final packing. After an initial run through a tumble dryer, the most effective way to finalise the drying process is by using a dedicated softgel drying tunnel machine. This ensures the capsules’ water content is reduced to the target levels with a gentle drying that preserves the quality of the capsule shell.
Working Principle of Softgel Drying Tunnel
The qualified soft capsule pressed by the main machine is sent to the rotating cage through the three-way transfer, and the blower is blown into the clean natural wind by the continuous rotation of the rotating cage to dry the capsule pellet. The capsule is left in the cage and when the cage is rotated counter clockwise (the person faces the feed port) by the button on the touch screen of the main unit, the capsule will automatically enter the next section when rotating clockwise. After drying, the capsule can be discharged at the last section of the cage outlet.
Each section of the cage is equipped with three fans. The total air volume is 960m3/h×24, which shortens the setting time. The capsules are shaped and dried when transferring from the beginning to the end, reducing costs and reducing floor space required. The layout can be reasonably extended according to the factory.
