For pharmaceutical and nutraceutical manufacturers, selecting the right capsule filling machine directly affects throughput, fill accuracy and long-term operating cost. The NJP-1200D automatic capsule filling machine is a third-generation, high-speed capsule filler engineered to meet GMP production requirements while handling even difficult-to-flow powders, including herbal and Chinese patent medicines. Reaching up to 72,000 capsules per hour with a filling accuracy of ±3% for Western medicine, this machine combines patented mechanical design, premium international components and a sealed, maintenance-light construction to support stable, round-the-clock production.

What Is the NJP-1200D Automatic Capsule Filling Machine?

The NJP-1200D is an automatic capsule filling machine designed for medium-to-large scale production lines in pharmaceutical, herbal and health-supplement plants. It fills empty and filled hard-shell capsules across sizes 00, 0, 1, 2, 3, 4 and 5, and is suitable for powder, granule, pellet and tablet materials. As an upgraded third-generation model, it retains all the core functions of comparable domestic capsule filling machines while introducing six structural and mechanical innovations—two of which were granted utility-model patents by the China National Intellectual Property Administration on 11 May 2016. The result is higher production efficiency, greater fill consistency and a longer service life compared with earlier-generation capsule filling equipment.

Key Technical Specifications of the NJP-1200D

The table below summarises the main technical specifications of the NJP-1200D automatic capsule filling machine.

Table 1. Main technical specifications of the NJP-1200D automatic capsule filling machine.

What Materials and Capsule Sizes Can the NJP-1200D Fill?

The NJP-1200D capsule filling machine is built for versatility. Its filling station handles a wide range of dry formulations:

• Powder — including Western pharmaceutical powders and herbal medicine powders
• Granules — free-flowing and lightly cohesive granulations
• Pellets — small spherical dosage forms and micro-pellets
• Tablets — capsule filling applications that require tablet payloads

It supports hard-shell capsule sizes 00, 0, 1, 2, 3, 4 and 5, giving production teams the flexibility to run multiple product formats on a single automatic capsule filler. The machine reports a filling rate of 99.9% for empty capsules and 99.8% for filled capsules, with a filling accuracy of ±3% for Western medicines and ±4% for Chinese medicines.

Six Core Innovations That Set the NJP-1200D Apart

The NJP-1200D automatic capsule filling machine was developed as an innovative third-generation product. It covers all the functions and effects of domestic capsule filling machines of the same model while adding six areas of innovation, two of which have been issued utility-model patent certificates by the China National Intellectual Property Administration. The improvements below are what make it a reliable high speed capsule filling machine for demanding production schedules.

1. Butterfly-Valve Powder Hopper for Poor-Flow Materials

A common problem in traditional capsule filling is powder bridging in screw-type feeding devices, especially with materials of poor liquidity. The NJP-1200D solves this with a new hopper that adopts butterfly-valve type powder feeding. An integrated vibration unit forces the powder to run down continuously, making the machine highly suitable for herbal medicine, Chinese patent drugs and other powders with poor flowability. The result is consistent, uninterrupted powder feed and fewer stoppages on the production line.

2. One-Piece, Fully Sealed Turntable (Patented)

The turntable frame of the NJP-1200D is formed by one-piece machining, giving a compact structure with no splicing gap, good sealing and easy disassembly. Individual modules move up and down independently—the lower die performs horizontal telescopic movement while the module moves vertically for lifting—and the fixed bracket shaft uses an oil-sealed, dust-proof lip skeleton shield. This fully enclosed turntable achieves low noise, small volume, low load and high precision, and is designed for three years of no maintenance, no refuelling and no powder leakage. This innovation is protected under utility-model patent no. ZL 2015 2 1021530.0.

3. New Internal-Groove Cam Transmission System

Instead of the traditional external cam, the NJP-1200D uses the latest CAM drive system with an internal groove cam for all running cams. The transmission bracket is designed to move up and down through this system, enabling precise, accurate, stable and noiseless operation even at high filling speeds. This upgrade reduces wear and vibration while improving the long-term reliability of the capsule filling equipment.

4. First-to-Market 100DS High-Precision Cam Indexing Box

Many domestic NJP-1200D-style machines rely on an 83DS cam indexing box, which limits practical filling speed to around 900 capsules per minute and risks input/output shaft breakage if pushed to roughly 1,000 capsules per minute. The NJP-1200D is the first in the domestic industry to use the 100DS high-precision cam indexing box (input shaft diameter 24 cm, output shaft diameter 30 cm). This configuration delivers larger torque, better stability and a longer service life, and raises the practical filling speed to approximately 1,100 capsules per minute. Although it increases production cost, it significantly enhances both production efficiency and equipment longevity, and has been widely accepted by customers at home and abroad.

5. Higher Production Efficiency and Longer Service Life

Taken together, the enlarged machine frame (main dimensions 1200 × 1000 × 2150 mm), the high-capacity cam indexing system and the sealed turntable design give the NJP-1200D a clear edge in output and durability. For pharmaceutical capsule filling lines that run continuous shifts, fewer moving-part failures and reduced maintenance translate directly into lower total cost of ownership.

6. Premium Electrical and Drive Components

The NJP-1200D is equipped with internationally recognised automation and drive components to support reliable, repeatable operation. Its main electrical accessories include a Siemens SMART 1000 IE V3 touch screen, Siemens PLC and contactors, a Schneider variable-frequency speed governor, a German SEW main motor, and high-precision cam indexing boxes from Daojin (Taiwan). Motion components include a Japanese dry vacuum pump, a self-manufactured dust collector, and linear and needle roller bearings from SAMICK, IKO and NSK. This bill of materials supports stable speed control, gentle capsule handling and dependable long-run performance.

Quality, Compliance and Standards

The NJP-1200D automatic capsule filling machine is manufactured to documented quality standards and is suitable for GMP-oriented production environments. According to the manufacturer’s quality guarantee, the machine:
