Name: Hard Capsule Filling Machine
Brand: YohoAI

Product Overview

High-speed automatic capsule filling for industrial-scale production

The NJP-3800 Fully Automatic Hard Capsule Filling Machine is designed for high-volume production of filled hard capsules in pharmaceutical, nutraceutical, and herbal medicine manufacturing. With a maximum output of 228,000 capsules per hour, it delivers industry-leading speed without compromising dosing accuracy.

Built with a servo-driven dosing system and CNC-machined dosing discs, the machine achieves filling accuracy of ±2% for powder formulations. The modular tamping mechanism ensures uniform capsule weight, while the quick-change mold system allows format changes between capsule sizes (000–0) in under 30 minutes.

The machine features product standardization and serialized production: the universal interchangeability of manufacturing parts reaches more than 98%. Each spare part has a fixed code, and the positioning-hole design of replacement mold parts ensures high repeated positioning accuracy. Mold replacement is fast, operation is simple, and cleaning is convenient.

How It Works

8-step automatic capsule filling process

Empty Capsule Feeding

Empty hard capsules (gelatin or HPMC) are loaded into the capsule hopper. A vacuum-driven separator splits each capsule into body and cap halves, orienting them into the dosing stations of the rotating turret.

Capsule Separation

The capsule bodies are seated in the lower bores while the caps are held in the upper bores. A vacuum system ensures reliable separation with a success rate exceeding 99.9% for standard capsules.

Power Dosing – Tamping

Powder from the feed hopper is drawn into the dosing disc cavities. A series of tamping pins (5-stroke) progressively compress the powder into uniform plugs. The tamping force and depth are servo-adjustable for each formulation.

Plug Ejection into Capsule Body

The tamped powder plugs are ejected from the dosing disc and deposited into the capsule bodies. The ejection pins ensure clean transfer without powder loss or cross-contamination.

Excess Powder Removal

Any residual powder around the capsule body rim is removed by a vacuum suction system. This ensures clean sealing surfaces and prevents powder leakage from finished capsules.

Capsule Closing

The upper bores carrying the caps are aligned with the lower bores containing filled bodies. Closing pins push the caps onto the bodies, applying controlled pressure to lock the capsules without damaging the shell.

Ejection & Collection

Finished capsules are ejected from the turret bores and directed into the output chute. An automatic counting and collection system sorts the capsules into containers for downstream processing.

In-Line Quality Check

An optional in-line weight checker or visual inspection system monitors capsule weight, integrity, and appearance in real time. Reject capsules are automatically diverted to a separate bin for review.
