NJP Series Hard Capsule Filling Machine

Professional Hard Capsule Filling Solutions

Designed for pharmaceutical, nutraceutical & herbal manufacturers

The NJP Series automatic capsule filling machines are engineered for pharmaceutical companies, nutraceutical manufacturers, and contract manufacturers requiring high-speed, precision encapsulation with GMP compliance.

Our machines utilize the proven tamping pin dosing system, where powder is compressed into a dosing chamber and then ejected into capsule bodies. This ensures:

Uniform dosing with ±3-5% filling accuracy across all capsule sizes (#000 to #5)
High production speed up to 228,000 capsules/hour for large-scale manufacturing
Flexible filling - powders, granules, pellets, micro-tablets, and combinations
Quick changeover - 20-30 minutes for size change with quick-change tooling

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

Frequently Asked Questions

What capsule sizes does the hard capsule filling machine support?

The machine handles all standard capsule sizes from #000 (largest) to #5 (smallest), including gelatin and HPMC capsules. Custom capsule sizes are available upon request. Size changeover takes 20-30 minutes using quick-change tooling.

Can the NJP hard capsule filler handle both powders and pellets?

Yes. The tamping pin system fills powders, granules, pellets, and micro-tablets reliably. For combination filling (powder plus pellet in the same capsule), YohoAI offers special dosing configurations to ensure uniform content distribution.

How long does it take to change over the NJP capsule machine to a different capsule size?

Standard changeover with quick-change tooling takes 20-30 minutes, and no special tools are required. Operators can perform changeover independently after initial factory training, minimizing downtime between production runs.

What does the installation and training package include for the NJP series?

Installation includes 5-7 days of on-site commissioning and operator training by YohoAI engineers at no extra cost. Customers also receive free process trials at the Shanghai factory to validate their specific formulation before machine acceptance.

What certifications does the NJP hard capsule filling machine carry?

The NJP series is CE certified and designed to cGMP and FDA standards. Documentation includes material certificates, DQ/IQ/OQ/PQ validation protocols, operation manuals, and preventive maintenance schedules for regulatory compliance.

What is the production capacity range of the NJP hard capsule filling machine?

The NJP series covers a capacity range of 30,000-228,000 capsules per hour depending on the model. The NJP-2000 delivers 120,000 caps/h, while the top-tier NJP-3800 reaches 228,000 caps/h, suitable for high-volume pharmaceutical production.

What filling accuracy can operators expect from the NJP capsule filler?

The NJP machine achieves +/- 3-5% filling accuracy, meeting pharmaceutical grade standards. This precision is maintained across all capsule sizes (#000 to #5) and fill types including powder, granules, pellets, and micro-tablets.

How much does an NJP hard capsule filling machine cost?

Pricing varies by model and configuration; typical industry range is USD 25,000-180,000. The NJP-800 starts around USD 25,000-35,000, mid-range NJP-2000 is USD 45,000-75,000, and the high-capacity NJP-3800 reaches USD 120,000-180,000. Request a quote for exact pricing.

Which NJP model is best for small-batch R&D versus large-scale production?

For R&D and small-batch runs, the NJP-800 or NJP-1200 (30,000-60,000 caps/h) offers an affordable entry point. Mid-scale production suits the NJP-2000 at 120,000 caps/h. Large-scale commercial output calls for the NJP-3800 at up to 228,000 caps/h.

What are the physical specifications of the NJP hard capsule filling machine?

The NJP-2000 standard model measures approximately 1,200 x 800 x 1,800 mm and weighs about 1,500-1,800 kg. It operates on a 5.5 kW power supply. The compact footprint fits standard pharmaceutical cleanroom layouts with minimal foundation requirements.
