In the production process of solid dosage hard capsules, capsule polishing machines are a critical link between the preceding and following stages. After the capsule filling process, some powder often remains on the surface due to factors such as powder fluidity and the encapsulation process. Some capsules may also have encapsulation defects. If these issues are not addressed before the packaging process begins, not only will the drug’s appearance appear rough and unprofessional, reducing consumer trust, but more seriously, substandard capsules may leak and deteriorate in subsequent processes, affecting the drug’s effectiveness and safety. The emergence of capsule polishing machines perfectly addresses these pain points. Through an integrated “polishing + sorting” process, it comprehensively cleans and screens capsules, ensuring that every capsule leaving the factory is pristine and meets quality standards.
In practice, automatic capsule polishing machine serves a wide range of pharmaceutical companies, from large multinationals to small and medium-sized enterprises focused on the research and development and production of specialty drugs. In the field of health product production, capsule polishing machines can help manufacturers improve the appearance and quality of their products, making them more in line with consumer expectations for high-quality health products. In the production of biologics, such as vaccines and bioactive factor capsules, the requirements for environmental and product quality are almost stringent. With their superior purification and sorting capabilities, capsule polishing machines have become a vital piece of equipment for ensuring the consistent quality of biologics, ensuring that every batch of biologic capsules meets stringent quality standards.
The reason why the pharmaceutical capsule polishing machine can efficiently complete the purification and sorting tasks is due to its exquisite structural design. Each component performs its own function and works together to build a sophisticated processing system.
The polishing cylinder is made of high-quality stainless steel and features a flexible spiral brush installed on its inner wall . When the capsule polisher machine is turned on, the capsule, driven by the rotating brush, moves in a circular spiral motion along a spiral path . This unique motion ensures full contact between the capsule and the cylinder wall and the brush. The finely divided openings on the cylinder wall allow impurities such as powder and debris to be drawn in immediately, preventing secondary contamination within the polishing cylinder.
Flexible Brush : Driven by a powerful motor, the high-speed rotating brush rotates at a precisely controlled speed, creating friction with the capsule surface. This gently yet effectively removes tiny particles adhering to the capsule surface, gradually restoring the capsule to a pristine, like-new appearance.
Rejection system : Using the principle of negative pressure airflow, light unqualified capsules, such as empty shells and fragments, are sucked into the collection box; while heavy qualified capsules fall steadily by their own weight and continue to enter the subsequent process.
Dust collector : The vacuum cleaner in capsule polisher uses powerful suction to collect dust and waste materials in the sealed cylinder for centralized treatment. The unqualified capsules screened out by the collector are not worthless. After proper treatment, some of the raw materials can be put back into production, which not only reduces production costs but also maximizes the use of resources.
Compliant design : In the pharmaceutical industry, Current Good Manufacturing Practice (cGMP) is a crucial guideline for ensuring drug quality, and the automatic capsule polisher is designed to strictly adhere to this principle. The main body of the equipment is constructed entirely of stainless steel, which is not only durable and corrosion-resistant, but more importantly, does not chemically react with drugs or release any harmful substances into the drug, ensuring the safety of the drug production process. The polishing cylinder has a unique structural design with no blind spots, facilitating thorough cleaning between production runs.
Furthermore, the equipment supports 10- minute quick disassembly and cleaning, allowing operators to easily disassemble each component for comprehensive cleaning and disinfection, ensuring that the equipment consistently meets the strict hygiene standards of cGMP.
Low maintenance cost : The polishing capsule machine was designed with ease of maintenance and cost control in mind. The wear-resistant brushes used in the machine have a service life of ≥2000 hours, which reduces the frequency of brush replacement and reduces maintenance costs.
Post-capsule processing after filling :
In pharmaceutical production , after the capsule filling process is completed, a thin layer of drug powder often adheres to the surface of the capsule, which may become a “hidden danger” in subsequent production links. The capsule polishing machine uses a high-speed rotating brush to closely contact the capsule surface, and with precisely controlled friction, it removes these residual drug powders one by one. During the polishing process, the sealing cylinder inside the equipment works in conjunction with the dust collection system, using the principle of negative pressure to quickly suck the stripped drug powder into the collection device.
This efficient treatment process not only makes the capsule surface look brand new and significantly improves the smoothness, but more importantly, it effectively prevents drug powder from causing capsule adhesion , inaccurate counting, and loose blister sealing in the subsequent production links of capsule counting and bottle filling machines and capsule blister packaging machines , thereby ensuring the efficiency and integrity of drug packaging.
Rejection :
In the pursuit of zero-defect pharmaceutical quality, the high speed capsule polisher’s rejection function is a solid line of defense. During the capsule polishing process, it uses an advanced waste remover, negative pressure airflow, and intelligent recognition technology to rigorously screen each capsule. Upon detecting unqualified capsules—empty, damaged, or with detached caps—the automated capsule polishing and screening machine precisely removes these “problem capsules,” preventing them from being mixed with qualified products.
This real-time screening mechanism effectively prevents unqualified capsules from impacting the entire batch , significantly reducing rework during subsequent quality inspections and saving the company significant manpower, material, and time costs.
Improved production line efficiency :
On modern pharmaceutical production lines, high speed capsule polishing machines are no longer isolated entities; they are closely integrated with other equipment. They seamlessly integrate with fully automatic capsule fillers. As filled capsules emerge from the filler’s outlet, they quickly enter the capsule polisher’s hopper, starting the polishing process. After polishing, they are smoothly transported to the inspection machine, preparing for further capsule packaging production.
This integrated production model automates the entire “filling-polishing-sorting-packaging” process, significantly shortening the single-batch production cycle by over 20% compared to traditional production methods. For example, after introducing a capsule polisher and optimizing the production line layout, a large pharmaceutical company reduced its single-batch capsule production time from 8 hours to less than 6 hours, significantly improving production efficiency.
Small and medium-sized production capacity (< 200,000 capsules/day) :
For smaller production companies, cost control and production flexibility are key considerations. Small horizontal capsule polisher, with their relatively simple structure and affordable price, can effectively reduce a company’s equipment procurement costs. They also offer high operational flexibility, allowing operators to manually adjust parameters such as brush speed and rack tilt angle to meet the production process requirements of different capsule products. In small-batch, high-variety production models, semi-automatic basic polishers can quickly switch production parameters, enabling alternating production of different products, providing small and medium-sized enterprises with efficient and flexible production solutions within a limited budget.
Large-scale production (>500,000 capsules/day) :
As companies move toward large-scale production, the requirements for production efficiency and product quality consistency increase significantly. At this stage, fully automatic vertical double-head capsule polishing and sorting machines become the preferred choice. This type of equipment offers efficient capsule processing, reducing the time and labor costs associated with manual loading. Its advanced sorting system accurately identifies and rejects substandard capsules while operating at high speed, ensuring that every capsule entering the packaging process meets high-quality standards. Furthermore, fully automatic sorting machines can be seamlessly integrated with other production equipment, such as capsule filling machines, high-speed capsule counters, and pharmaceutical capsule blister packaging machines , creating a fully automated production line. This significantly improves production efficiency and meets the demanding requirements of large-scale production.
Throughout the lifecycle of a capsule polishing machine, a comprehensive service guarantee system is crucial for ensuring stable equipment operation and smooth production. Prioritize suppliers that can provide certification documents such as CE, ISO, RoHS, and cGMP , as this strongly demonstrates the equipment’s compliance and quality reliability. Verify that the supplier has extensive experience in overseas on-site commissioning, including equipment installation, commissioning, and personnel training. Also, ensure they provide comprehensive technical documentation, including user manuals, detailed machine operation guides, technical white papers, machine operation videos, and videos on routine maintenance and cleaning. These are key criteria for verifying the professionalism of a high-speed capsule polisher manufacturer.
From surface polishing to intelligent sorting, capsule polishing machines are reshaping pharmaceutical capsule production with innovative technology, transcending mere quality control. With the increasing application of automation and intelligent technologies, this capsules polisher automatic will play an even more critical role in future pharmaceutical production.
