Professional Softgel Encapsulation Solutions

Designed for pharmaceutical, nutraceutical & cosmetic manufacturers

The NJP Series rotary die softgel encapsulation machines are engineered for pharmaceutical companies, contract manufacturers, and nutraceutical producers requiring high-precision capsule production with consistent quality and GMP compliance.

Our encapsulation systems utilize the proven rotary die process, where two continuous gelatin ribbons are formed, filled with your formulation, and sealed simultaneously between rotating dies. This method ensures:

  • Consistent capsule weight with ±1-2% filling accuracy via servo-controlled dosing pumps
  • Uniform sealing for leak-proof capsules even with sensitive formulations (probiotics, omega-3, essential oils)
  • Flexible production with quick-change die system (15-30 min changeover)
  • Material versatility - gelatin, HPMC, and pullulan capsule shells

All contact parts are fabricated from 316L stainless steel with pharmaceutical-grade surface finish (Ra ≤ 0.4 μm). The machines are designed for CIP (Clean-in-Place) compatibility and meet cGMP, FDA 21 CFR Part 11, and EU GMP requirements.

Rotary Die Encapsulation Process

Industry-standard technology for consistent capsule quality

1

Gelatin Preparation & Spreading

Medical-grade gelatin or HPMC solution is prepared at 55-65°C in a thermostatic tank. The molten gelatin is spread onto a cooling drum to form two continuous ribbons (thickness: 0.6-1.2mm, adjustable).

2

Ribbon Formation & Lubrication

Gelatin ribbons pass through a lubrication system (food-grade mineral oil) to prevent sticking. Ribbon temperature is maintained at 35-40°C for optimal forming properties.

3

Encapsulation & Filling

The two ribbons converge between the rotating die rolls. As die pockets form, the precision dosing pump injects the fill material (oil, suspension, or paste) at ±1-2% accuracy.

4

Sealing & Cutting

Hydraulic pressure (0.3-0.8 MPa) seals the capsule edges as the die rolls rotate. Individual capsules are cut from the ribbon by the die pockets.

5

Capsule Ejection & Collection

Formed capsules are ejected onto a conveyor and transferred to the initial drying tumbler. Wet capsules contain 20-30% moisture at this stage.

6

Drying & Quality Control

Capsules are dried in a controlled environment (25°C, 30% RH) for 4-8 hours to reach final moisture content (6-10%). Weight variation, sealing integrity, and appearance are inspected per USP/EP standards.
