Hard Gelatin Capsule Filling Machine Made in China

Capsule filler is an essential piece of equipment in the pharmaceutical and health product manufacturing industries. Capsule filling machine is a specialized equipment that automatically transfers, spreads, fills and locks capsules. Not only is it widely used in the field of pharmaceutical production, it can also meet the needs of large-scale production of enterprises, greatly saving financial resources and manpower investment.

Types of Hard Capsule Filling Machines

Fully automatic capsule filling machines have become the most economical and practical equipment for filling capsule-form medicines in the pharmaceutical industry. Based on their mode of motion, fully automatic capsule filling machines are mainly divided into intermittent-motion and continuous-motion types; according to their structural design, they can be classified as either dosing-disk style or syringe style. Currently, in large-scale production, the dosing-disk type is predominantly used.

On the market today, capsule filling machines are generally available in three variants: manual, semi-automatic, and fully automatic. Among these, fully automatic capsule filling machines—owing to their greater professionalism and safety—are increasingly becoming the cost-effective choice for filling capsule products in the pharmaceutical and nutraceutical industries, and their market sales are showing a strong upward trend.

How to Improve the Filling Quality of Capsule Filler?

In addition to the quality of the equipment itself, the equipment environment, transportation process, and various stations will all have an impact on the filling quality. Users need to pay special attention to several positions of the equipment when operating, including the following parts:

Capsule Positioning and Separation Station

This station ensures precise separation of the capsule cap from the body prior to powder filling, preparing for subsequent processes. Common issues include capsule scattering and incomplete separation, which reduce efficiency and may damage equipment or compromise product quality. Technicians emphasize the importance of accurate vacuum pressure calibration and using high-quality capsules from certified manufacturers to enhance separation stability and consistency.

Powder Filling Station

Responsible for filling measured amounts of powder into capsule bodies, this station is critical for dose uniformity. Uneven filling weights, often caused by mechanical misalignment or uneven powder distribution, are common challenges. Solutions include ensuring precise alignment of the metering disc with the lower module, maintaining a gap of 0.05–0.1 mm between the metering disc and spacer, and continuously monitoring powder distribution on the disc to achieve consistent filling.

Defective Capsule Removal Station

This station identifies and removes improperly separated or defective capsules to ensure only qualified capsules proceed. Issues include incomplete removal or excessive suction of intact capsule caps. Adjusting the negative pressure suction to a level sufficient for removing defective capsules—while avoiding excessive force that could damage intact capsules—is essential.

Capsule Locking Mechanism

This mechanism securely re-locks capsule caps and bodies to form the final product. Common problems include capsule cracking, improper locking, or damage. Precise alignment of upper and lower modules and optimizing the locking stroke length are crucial to ensure firm yet non-destructive closure.
