What is a Capsule Polisher?
A capsule polisher is a machine designed to clean, polish and de-dust hard capsules or tablets after filling or compression — removing residual powder, restoring a smooth surface, and improving the final appearance and cleanliness of pharmaceutical and nutraceutical capsules or tablets. These machines offer a critical finishing step before packaging, ensuring capsules are free from powder, look professional, and meet hygiene and quality standards.
Key Features & Working Principles
How It Works
Capsules or tablets are fed into a stainless-steel polishing chamber.
A revolving spiral nylon brush (or double-brush system in some versions) gently rolls the capsules while filter cloth and airflow extract loose powder and dust.
Clean, polished capsules emerge at the outlet, often with an integrated dust-collector or connection to a dust-extraction system, ensuring minimal contamination or dust exposure.
Major Advantages
Improved Appearance & Cleanliness: Removes powder residues, dust, or granule fragments — giving capsules a clean, glossy, sale-ready finish.
Quality Compliance: Built from stainless steel, designed to meet GMP / pharmaceutical hygiene standards; ideal for hard gelatin, HPMC, or vegetable capsules.
Flexible Compatibility: Suitable for various capsule sizes (e.g. 00, 0, 1, 2, 3, 4, 5) and compatible with capsules filled with powders, granules or pellets.
Seamless Integration: Capsule polishers can be integrated into semi-automatic or fully automatic capsule filling lines, or operate as standalone finishing machines in existing workflows.
Applications & Industry Use Cases
Capsule polishers are widely used in:
Pharmaceutical manufacturing lines — for cleaning and finishing hard capsules before packaging.
Nutraceutical, supplement, and herbal product production — especially where capsule appearance and hygiene are critical.
Contract manufacturing and third-party packaging services — polishing capsules after filling to meet client or regulatory standards.
Health, wellness, and herbal product factories producing medium-to-large batches, where automated cleaning greatly improves throughput and reduces manual labor.
Available Versions & Configurations
Depending on production needs, capsule polishing machines come in several configurations:
Single-Brush Vertical Capsule Polisher — compact and cost-effective, suitable for small to medium output; ideal for supplement or small-batch pharmaceutical production.
Double-Brush / High-Efficiency Polisher — higher throughput and more thorough polishing, better for medium to large scale production or continuous capsule filling lines.
Polisher with Integrated Sorter / Dust Collector — advanced versions including dust extraction, capsule sorting, or compatible modules for full automation workflows.
Each version can be tailored to support different capsule sizes, output volumes, and cleanliness standards, depending on client requirements.
