High Speed Automatic Capsule Filling Machine

A High Speed Automatic Capsule Filling Machine is an advanced piece of pharmaceutical and nutraceutical equipment designed to fill hard gelatin or vegetarian capsules with powders, pellets, granules, or other materials at high production rates. These machines automate the entire process—orienting, separating, filling, and closing capsules—ensuring precision, consistency, and compliance with standards like GMP, CE, and ISO. They are widely used in industries for producing supplements, medications, and herbal products, significantly reducing labor costs and increasing efficiency compared to manual or semi-automatic fillers.

Unlike semi-automatic models, which require operator intervention and produce 18,000–25,000 capsules per hour, fully automatic high-speed machines operate continuously with minimal supervision, achieving outputs from 54,000 to over 150,000 capsules per hour. They feature tamping mechanisms for accurate dosing, sensors for uninterrupted feeding, and automatic rejection of defective capsules.

Key Features and Benefits

• High Output and Speed: Capable of filling 900–2,500 capsules per minute, depending on model and capsule size. This supports large-scale production and faster time-to-market.

• Versatility: Handles capsule sizes from #000 to #5 and various fill types. Adjustable tamping stations and dosing disks allow precise weight control.

• Ease of Use and Maintenance: Touchscreen interfaces, PLC controls, and stepless frequency converters for simple operation. Low noise, easy cleaning, and quick mold changes minimize downtime.

• Quality and Safety: Stainless steel construction, vacuum ejection of defects, and integrated sensors for hoppers. Many include Process Analytical Technologies (PAT) for real-time monitoring, such as powder height and ejection force detection.

• Efficiency and Cost Savings: Reduces powder spillage, ensures >99.99% capsule loading rate, and supports containment systems for handling potent compounds safely.

• Customization: Options for R&D scalability, integration with other lines, and validation for cGMP compliance.

These machines lower overall production costs by automating tasks, conserving energy, and requiring fewer operators—often just one to monitor multiple units.

How They Work

1. Capsule Feeding: Empty capsules are loaded into hoppers and oriented automatically.

2. vSeparation and Filling: Caps are separated from bodies via vacuum or mechanical means. Powder/granules are dosed using augers or tamping pins for multi-stage compression, ensuring uniform fill weights.

3. Closing and Ejection: Bodies and caps are rejoined, defective units are rejected, and filled capsules are discharged for further processing.

4. Monitoring: Sensors detect issues like low material levels; advanced models use IPC for automated adjustments.

Applications and Considerations

Ideal for pharmaceutical, nutraceutical, and cosmetic production. Ensure compatibility with your materials—some machines excel at sticky powders, others at pellets. Regulatory compliance is key; look for CE/GMP certification.

Salient Features of Automatic Capsule Filling Machine

• Compact cGMP model.

• Programmable Logic Control (PLC) & display of all operations

• All the drive elements and the cabling at the bottom side separate panel

• Crevice free smooth stainless steel pharmaceutical grades

• Automatic intermittent motion Driving Zone completely separate at bottom and production zone at upper side.

• Fill weight can be easily achieved by dosing disk thickness; the weight variation can be maintained ± 3% by accurate dosing disc.

• Powder sensor maintains constant level of powder in the dosing chamber and there will alarm in case of low level of powder in dosing chamber.

• Easy to operation by central control touch screen and easy to change dosing disc, tamping pins, capsule feeding & orientation parts, capsule segments.

• Product contact parts are 316L SS and the other parts non-corrosive material.

• Capsule can fill powder or pellets.

• Non-separated capsule will be ejected automatically.

• Option of attaching Capsule Polisher Line which includes capsule polishing, sorting, metal detection machines.

• IQ/OQ documentation can be provided.

• Sampling system can be provided on demand.

Process Operation of Automatic Capsule Filler Machine

After starting up the machine, the empty capsules in hopper will be fed into the slot of magazine vertically. With each stroke of machine, the fingers of magazine will release one row of capsules into rectifier raceway. The horizontal fingers rectify the direction of capsules and vertical fingers push the capsules into hole of segment with all caps on the up position. The capsules in the holes are sent to each working station along with the intermittent rotation of the turn table.

• At the 1^st & 2^nd station, the vacuum system separates the capsules in position.

• At 3^rd station, the lower segment with capsule body extends out ready for the filling.

• 4^th station uses to fill pellets.

• At the 5^th station, the tamping pins push the pressed powder slug into capsule body.

• 6^th station to re-joint cap & body segments.

• At 7^th station non-separated capsule get eject.

• At 8^th station vertical pins pushing body of capsule into the cap for re-join and close the filled capsules.

• The 9^th station is to eject the finished capsules.

• At the 10^th station the holes of segments are cleaned by vacuum cleaner and compressed air. Then the segments are ready for next cycle of operation.

The powder from a SS hopper entered to a chamber of dosing plate & temping pins for dosing, the height of the powder is controlled at chamber by a material level sensor. Tamping device is work by a 6-working station of intermittent mechanism, there are 6 groups of standard holes on dosing disc. The powder filled in holes was made of a slug that reaches the weight of dose after 5 tamped. At the 6th working station the slug pushed by tamping pin into capsule body. Adjusting the height of tamping pin holder can be changed the filling weight of powder.
