Automatic filling machine NJP-3800D

capsulefor tabletspowder

Product overview
NJP-3800D automatic capsule filling machine is engineered for high-speed filling of empty hard capsules with powders, granules or small tablets for pharmaceutical and nutraceutical production. The unit integrates automated capsule feeding, separation, precise dosing, filling, locking and discharge to support continuous production.

How it works

• Capsule separation: divides capsules into body and cap for dosing.
• Dosator/piston filling: metered powder delivery into capsule bodies.
• Locking/sealing: mechanical or pneumatic closure to prevent leakage.
• Inspection and rejection: real-time detection and automatic ejection of defective capsules.
• Output: filled capsules discharged for downstream packaging.

Specification (summary)

• Production capacity: up to 228,000 pcs/h.
• Capsule sizes supported: 000, 00, 0, 1, 2, 3, 4, 5.
• Suitable materials: powder, granule, pellet, tablet.
• Power supply: 380/220V 50Hz (customizable).
• Noise level: <72 dB(A).

Main Features

• Continuous operation with integrated feeding, sorting, dosing, locking and discharge for long production runs.
• Automatic defect detection and rejection with high accuracy (compliant with cGMP/ALCOA+ practices).
• Quick mold/metering plate change via modular design (≤15 minutes).
• Multi-station configuration to separate functions and optimize throughput.

Main Parts

• Capsule feeding/sorting unit (double-feed handling).
• Dosator/powder filling station.
• Rejection/inspection station.
• Capsule locking/sealing station.
• Discharge/output station and transfer interfaces.
• Inspection systems: visual/weight/optical sensors.

Advantages

• High throughput suitable for large-scale pharmaceutical or nutraceutical production.
• High equipment utilization and extended continuous run capability.
• Integrated inspection and automatic rejection to secure product quality.
• Fast tooling change for flexible production across capsule sizes.

Technical guidance: powder leakage reduction & filling accuracy (key measures)

• Powder formulation: use flow aids, control humidity (approx. 35–45%), optimize particle size (target 50–150 μm) and apply antistatic measures.
• Feeding system: variable-frequency vibratory feeders, anti-bridging hopper design, flexible agitators and micro-negative-pressure dust collection above the metering plate.
• Filling control: multi-stage compression, slow punch withdrawal and local vacuum/seal around the metering area.
• Metering plate precision: tight machining tolerances (clearance ≤10 μm), mirror finish and wear-resistant coatings (DLC/TiN); use online calibration where available.
• System control: closed-loop feedback (visual AI inspection, piezo sensors) and automatic adjustment routines.
• Validation and environment: follow IQ/OQ/PQ, maintain controlled temperature/humidity and implement dust management.
