Quick Answer
What Is a Powder Capsule Filling Machine?
A powder capsule filling machine is automatic pharmaceutical equipment that separates empty hard-gelatin or vegetarian capsules, doses precise amounts of powder into the capsule body using a multi-bore tamping system, then locks and ejects finished capsules. The HIJ NJP-800C fills up to 48,000 capsules per hour with ±3.5% dosing accuracy and a ≥99% capsule qualified rate, handles capsule sizes 00# to 5# plus safety capsules A–E, and is built with 304 stainless steel contact parts in a fully enclosed dosing station. It is manufactured cGMP-ready and CE-marked by HIJ Machinery (Wenzhou Trustar Machinery Technology Co., Ltd), a capsule filling machine factory founded in 2004 in Wenzhou, China. Base configuration starts around USD 17,500 FOB China including one mold set and dust collector.
Output: 800 capsules/minute (48,000/hour) — sized for mid-volume pharma and nutraceutical production lines.
Precision: Multi-bore tamping dosing holds fill-weight variation to ±3.5%, critical for label-claim compliance.
Versatility: Fills pharmaceutical powders, herbal/TCM blends, probiotics, and nutraceutical formulas; pellet and tablet dosing optional.
Compliance: cGMP-ready design, CE-marked, ISO 9001 manufacturing standard; full IQ/OQ documentation support provided for your validation.
Four Powder Encapsulation Problems the NJP-800C Was Engineered to Eliminate
Powder is the most demanding dosage form to encapsulate. Flowability, density, and static behavior change from batch to batch — and most rejected capsule lots trace back to one of these four failure points.
Fill-Weight Variation
Poorly flowing powders cause under- and over-filled capsules that fail weight checks. The NJP-800C's multi-bore tamping dosing compacts powder in progressive stages, holding variation to ±3.5% even with cohesive herbal blends.
Powder Loss & Dust
Open dosing stations bleed expensive API into the room. The NJP-800C uses a fully enclosed dosing station and turret plus an integrated dust collector, recovering powder and protecting operators.
Slow Cleaning & Changeover
Batch changeover downtime kills OEE. Tool-assisted mold changes between capsule sizes 00#–5# and quick-strip 304 stainless contact parts cut cleaning from hours to under 60 minutes for a trained operator.
Audit & Documentation Gaps
Regulators ask for evidence, not promises. Every NJP-800C ships with material certificates, FAT records, and IQ/OQ documentation support so your team can execute validation without chasing paperwork.
How the NJP-800C Powder Capsule Filling Machine Works: 6 Automated Stations
One intermittent-motion turret cycle completes the entire encapsulation process. Every station is cam-driven on Japanese linear bearings for repeatable, sub-millimeter positioning at 800 capsules per minute.
1
Capsule Feeding & Orientation
Empty capsules drop from the hopper into orientation rails that align every capsule body-down before insertion into the segment bores.
2
Vacuum Separation
Calibrated vacuum (-0.02 to -0.06 MPa) pulls the capsule body from the cap. Unseparated capsules are automatically diverted before dosing.
3
Multi-Bore Powder Dosing
Tamping pins compress powder into slugs inside the dosing plate through five progressive stations, then transfer each slug into the capsule body at ±3.5% accuracy.
4
Defect Rejection
Sensors reject unopened or damaged capsules before locking, protecting the ≥99% qualified rate. The machine auto-pauses when powder or capsules run low.
5
Locking & Ejection
Caps and filled bodies are rejoined and locked to the correct closed length, then ejected to the outlet chute or directly into the JFP-110A polisher.
6
Die-Hole Cleaning & Recovery
Compressed air and the integrated dust collector clean every segment bore each cycle, recovering residual powder and preventing cross-contamination between cycles.
Why Manufacturers in 30+ Countries Choose the NJP-800C Automatic Powder Capsule Filler
The NJP-800C was designed opposite to conventional open-station Chinese models: fully enclosed, PLC-controlled, and built with imported precision components for round-the-clock production.
Fully Enclosed Dosing Station
Unlike open-style turrets common in this class, the enclosed dosing station and turret contain dust, stabilize powder bed density, and keep the fill environment consistent shift after shift.
Japanese Linear Bearings & Lubricated Cam
Beeline bearings imported from Japan and a pressure-pulverization oil pump keep the working-station cam fully lubricated — extending component life and holding dosing precision over years of use.
PLC + Touchscreen Control
Stepless frequency-conversion speed control with digital readout. Operators adjust output, monitor counts, and review alarms from one HMI — minimal training required.
±3.5% Multi-Bore Dosing Precision
Progressive tamping across multiple bores delivers a ≥99% capsule qualified rate for both Western pharmaceutical powders and traditional Chinese medicine blends.
Operator & Machine Protection
Safety interlocks guard the operator; automatic pause triggers when powder or empty capsules run out, preventing empty-capsule lots and mechanical stress.
cGMP-Ready 304 Stainless Construction
All powder-contact parts are 304 stainless steel, quick-detachable for wash-down. CE-marked and built to ISO 9001 manufacturing standard, with documentation to support your IQ/OQ/PQ.

Forester's Insight
The Spec Sheet Never Tells You How Your Powder Flows
In more than twenty years of commissioning capsule fillers, the single most common mistake I see buyers make is choosing a machine from a parameter table alone. Two powders with identical particle size can behave completely differently in the dosing station — one flows like sand, the other bridges in the hopper and packs unevenly. That is why we test-run every NJP-800C with the customer's actual powder or a matched placebo before it leaves our factory.
Low bulk-density botanical powders are the classic trap: on gravity-fed machines they produce capsules that pass a visual check but fail weight sorting by ten percent or more. The progressive tamping design of the NJP-800C compacts the powder into a slug in stages, so by the time it transfers into the capsule body, the density is already locked in. Send us 2–3 kg of your formulation — the trial costs you nothing and it removes the biggest unknown in your purchase.

Powder Capsule Filling Machine FAQ
Direct answers from our engineering team to the questions international buyers ask most before purchasing the NJP-800C.
How much does a powder capsule filling machine cost?
The NJP-800C powder capsule filling machine starts around USD 17,500 FOB China in base configuration, including one capsule mold set, dust collector, and PLC touchscreen control. Optional equipment such as extra mold sets, a capsule polishing machine, vacuum powder feeder, or automatic empty capsule loader adds USD 2,000–3,000 each. A complete production-ready setup typically lands between USD 20,000 and 28,000 depending on configuration.
What is the output of the NJP-800C powder capsule filling machine?
The NJP-800C fills up to 48,000 capsules per hour, equivalent to 800 capsules per minute. Real-world sustained output depends on powder flowability and capsule quality; most customers run at 85–95% of maximum speed for stable 24-hour production.
Which capsule sizes can the NJP-800C handle?
The machine fills standard capsule sizes 00#, 0#, 1#, 2#, 3#, 4#, and 5#, as well as Supro/safety capsule sizes A through E. Each size requires its own mold set, and changeover takes under 60 minutes for a trained operator using basic hand tools.
What filling accuracy does a powder capsule filling machine achieve?
The NJP-800C holds fill-weight variation to approximately ±3.5% using multi-bore progressive tamping dosing, with a capsule qualified rate of 99% or higher. Accuracy on your specific formulation is confirmed during the pre-shipment factory test run with your actual powder or a matched placebo.
What types of powder can be filled?
The NJP-800C fills pharmaceutical API powders, nutraceutical and vitamin blends, herbal and traditional Chinese medicine powders, and probiotic formulations. Free-flowing granulated powders give the best accuracy; cohesive or low bulk-density powders are handled by adjusting tamping depth and dosing-disc thickness. Pellet and tablet dosing units are available as options for combination fills.
Is the NJP-800C cGMP compliant?
The NJP-800C is designed cGMP-ready: all powder-contact parts are 304 stainless steel, the dosing station is fully enclosed, and surfaces are quick-detachable for cleaning and inspection. The machine is CE-marked and built to ISO 9001 manufacturing standard. Formal validation (DQ/IQ/OQ/PQ) is executed by your facility, and HIJ Machinery supplies the full documentation package to support it, including material certificates, FAT records, and IQ/OQ templates.
How long do cleaning and changeover take?
A full product changeover — stripping contact parts, wash-down, and installing a different capsule size mold — takes a trained operator under 60 minutes. Routine end-of-batch cleaning is faster because the dosing station, hopper, and segment bores disassemble without special tools, and the integrated dust collector removes residual powder during operation.
What is the difference between a powder and a liquid capsule filling machine?
A powder capsule filling machine like the NJP-800C doses dry powder into capsule bodies using tamping pins and a dosing plate, then locks the capsule mechanically. A liquid capsule filling machine pumps oils or liquid formulations into the capsule and then band-seals the joint to prevent leakage, which requires an additional sealing station and slows output. Choose powder filling for dry actives and liquid filling for oils, essential fatty acids, and liquid herbal extracts.
