NJP-400C Automatic Capsule Filling Machine— 24,000 Capsules/Hour
The NJP-400C fills 24,000 capsules an hour. It’s the step up from the 200C when product development turns into steady commercial runs.
1.Output: 24,000 capsules an hour as a sustained rate
2.Fill weight accuracy: ±3% on pharmaceutical powder, ±4% on herbal powder
3.Versatility: Supports capsule sizes #000 to #5 with modular tooling for rapid changeovers.
4.Powder handling: Vibration-assisted butterfly valve hopper — force-feeds sticky herbal powders that jam a screw feeder
Is the NJP-400C the right filler for you?
✓ This is a fit if…
- You need around 24,000 capsules an hour as a sustained rate
- You're running product development, stability batches or small commercial runs
- You're filling powder, granule or pellets
- You run 00# to 5# capsules
- Your room holds 21 °C ± 3 °C and 40–60% humidity
✕ Look elsewhere if…
- You need more than 24,000 an hour → the NJP-800C runs 48,000 for a modest step up
- This is your only machine and you plan to scale within a year → buying the 800C now costs less than buying the 400C twice
- You're doing bench-scale R&D only → a semi-automatic filler costs a fraction of this
- Your powder is very fine and highly potent → an enclosed rotary machine with dust extraction is not the same as a contained or isolator system. Tell us your OEB band first
- You need under 12,000 an hour → the NJP-200C costs less and does the same job at that rate
- You need more than 24,000 → the NJP-800C runs 48,000
- Precision Filling： Tamping pin technology ensures ±1% accuracy.
- Full GMP-Standards： Product-contact parts in 316L stainless steel with EN 10204 3.1 mill certificates
- Modular Tooling： Rapid changeover in less than 20 minutes.

The D suffix is a configuration, not just a speed step. C-type machines use a water-ring vacuum pump and external-groove cam lubrication. The D adds a dry vacuum pump — no water to refill, no scale build-up — plus enclosed internal-groove cams with automatic timed oiling, and a nano anti-corrosion coating over the same pharmaceutical-grade stainless steel. If your formulation is corrosive or your maintenance team is thin, that’s what you’re paying for.
Integrated control cabinet
Featuring a sleek, ultra-compact footprint with a fully integrated Siemens PLC control panel, this system eliminates the bulky external control boxes of traditional machines. It maximizes cleanroom efficiency while providing world-class automation and precision in a simplified, space-conscious structure.
Precision-Engineered Multi-Station Rotary Workflow
Featuring a sophisticated 10 stations indexing system, our workbench synchronizes every stage of the process—from precise capsule separation and multi-stage filling to intelligent waste removal and secure locking. This streamlined, modular workflow maximizes production consistency while offering reserved extension stations for future functional upgrades.
Oil-Free Dry Vacuum System for Superior Cleanliness
Equipped with a high-performance imported dry vacuum pump, our system ensures an ultra-quiet, oil-free operation that aligns with rigorous international cleanroom standards. Designed for maximum uptime, the system simplifies maintenance—requiring only a quick one-minute filter cleaning per shift to keep your production running at peak efficiency.
Keeping Powder Out of the Drive System
The enclosed turntable runs three years without internal maintenance or manual oiling with a dual-lip skeleton dust ring to prevent powder ingress.
How Much API Are You Losing per Batch?
A sophisticated negative-pressure system recycles stray powder, delivering cost savings for high-volume runs.
Running at 24,000/h Without Losing Fill Accuracy
Unlike smaller models, the NJP-400C utilizes a 10-station workflow to ensure more precise capsule separation and locking at higher speeds.
Industrial Applications
Changeover: what you change and how long it takes
What you changed | What gets adjusted | Roughly how long |
Same capsule, different fill weight | Tamping pin depth on the dosing station | 15-30mins |
Fill weight beyond the adjustment range | Swap the dosing disc for a different thickness | 15-30mins |
Different capsule size | Full tooling set: upper and lower modules, tamping pins, capsule tubes, alignment combs, feeding combs, dosing disc, alignment bars | 15-30mins |
Dosing disc thickness is the second lever. When tamping depth reaches its mechanical limit and you still can’t hit your target fill weight, you change the disc rather than fighting the machine. It’s a physical volume change, not a calibration.
The gaps matter more than they sound. Dosing disc to copper ring: 0.08–0.12 mm. Isolation block to disc: 0.05–0.1 mm. Every disc change means resetting the second one. Too tight and the disc binds; too loose and powder leaks and your fill weight scatters.
Cleaning is the long part. Between products, the powder hopper, dosing ring, upper and lower modules, tamping pins and dosing disc all come out. Parts above the machine table are cleaned with alcohol on lint-free cloth — never gasoline, kerosene, hydrogen peroxide or acetone.
What to check before you order — from any supplier
Ask to see the machine running your powder, not a demo powder
Lactose and starch run beautifully on everything. Ask for a video of your own material, or send a 2 kg sample for a trial run. Any factory that won't do this is telling you something.
Ask what the sustained rate is, not the maximum rate
Catalogue output figures are peak numbers. Ask what the machine holds over an eight-hour shift with your fill weight and your capsule size, and what the reject rate looks like at that speed.
Ask for the operating manual before you pay
If the adjustment procedures aren't in it — tamping pin height, dosing disc clearances, vacuum settings — your operators will be calling the factory every time something drifts.
Ask which parts are wear parts and what they cost
On a capsule filler that means seals, tamping pins and the dosing disc. Get the list and the prices in writing with the quotation.
Ask what the electrical supply actually is
Most machines from Asia ship at 380V / 50Hz as standard. Confirm in writing that yours will arrive configured for your plant, and whether the output figure still holds after the change.
Ask who installs it and who trains your operators
"We provide installation support" can mean an engineer on your floor or a PDF. Ask which, ask for how many days, and ask what happens if commissioning takes longer.

Why buy this machine from us
Accuracy you can check Fill weight accuracy is ±3% on pharmaceutical powder, ±4% on herbal powder. We run your material at factory acceptance testing and give you the actual figures for your formulation — not a number off a brochure.
The manual your operator can actually use An English operating and maintenance manual with the adjustment procedures in it — tamping pin height, dosing disc gaps, vacuum pressure. Ask to see it before you order.
Installation and training on site Our engineers install it, dial it in on your powder, and train your operators before they leave.
Factory-direct engineering You buy from the plant that builds the machine. Custom tooling, feeder configurations and change parts are a conversation with our engineers, not a request passed down a chain.
NJP-400C Performance & Technical FAQ
Absolutely. The NJP-400C is engineered with a reinforced drive system and an upgraded Siemens thermal management module. This allows it to maintain a stable, high-speed output for multi-shift operations without the overheating or vibration issues common in entry-level machines.
Efficiency is key for the NJP-400C. Our modular tooling design allows a single operator to perform a complete size changeover in approximately 20 minutes. The Siemens HMI stores up to 100 product recipes, enabling instant recall of filling parameters to minimize downtime between batches.
At 400 capsules per minute, traditional unified movements create excessive friction. Our NJP-400C separates vertical lifting and horizontal stretching planes. This reduces mechanical stress and heat buildup, ensuring that filling precision (±3%/±4%) remains consistent even after hours of high-speed running.
The NJP-400C is designed for a low Total Cost of Ownership (TCO). The enclosed rotary table with the double-lip dust ring protects all internal bearings from powder ingress. This unique design allows the enclosed turntable runs three years without internal maintenance or manual oiling., significantly reducing your annual OPEX (Operating Expenses).
The system utilizes a physical isolation barrier. Recycled powder is collected through a dedicated negative-pressure circuit that is completely separate from the waste capsule discharge station. This ensures that only pure, usable powder is recovered for immediate re-use, maintaining batch purity.
Standard NJP-400C units have a lead time of 6-8 weeks. For the U.S. market, we provide comprehensive remote FAT (Factory Acceptance Testing) via 4K live stream. Upon arrival, we offer step-by-step video installation guides and remote FAT, video installation guidance, and time-zone-based response.
