Horizontal Capsule Polishing Equipment

In pharmaceutical manufacturing, capsule finishing is a critical step that directly impacts downstream packaging efficiency and product presentation. A capsule polisher is designed to clean and remove residual powder from the surface of filled capsules after encapsulation. This is achieved through a combination of gentle mechanical agitation and vacuum suction, ensuring that capsules are free from dust and debris before they move to inspection or packaging.

Capsule polishers are compatible with a wide range of capsule sizes and types, including gelatin and HPMC-based variants. Constructed from GMP-compliant materials such as stainless steel and FDA-approved polymers, these machines are engineered to meet the rigorous hygiene and validation standards required in pharmaceutical production environments. Modular design and tool-less disassembly facilitate rapid cleaning and reduce changeover times between batches.

Advanced models integrate a weight-based capsule sorting mechanism into the polishing system. This feature allows capsules to be simultaneously polished and sorted by weight as they pass through the equipment. Using precision load cells or other dynamic weighing technologies, capsules are assessed in real time, and those that fall outside pre-set weight thresholds can be automatically diverted.

This type of weight-based sorting is particularly valuable in applications where uniform fill weight is critical to dosage accuracy and regulatory compliance. Unlike visual or structural inspection systems, weight-based sorting ensures that capsules meet mass specifications without the need for manual sampling or offline testing, enabling continuous in-line quality assurance.

The integration of polishing and weight sorting into a single, compact unit optimizes floor space utilization and reduces the need for multiple standalone machines. It also minimizes product handling, which can reduce the risk of contamination or mechanical damage.

For high-throughput manufacturing lines, a capsule polisher with weight-based sorting offers a streamlined, reliable solution for capsule cleaning and in-line mass verification. These systems are typically PLC-controlled, with options for data logging and integration with MES/SCADA platforms, enabling full traceability and process control.

Whether used as part of a continuous processing line or in batch operations, capsule polishers and polishing systems with integrated weight-sorting capability are essential tools for maintaining pharmaceutical product quality, consistency, and regulatory compliance.

Option: This capsule Polisher can be just a polisher or can be ordered with sorting function to reject short of unfilled capsules.

Maximum production capacity: 400 000 capsules/hour.
