Flexible Tablet Coating Solution for Mid-Scale Pharmaceutical Production

High-Precision Tablet Coating Solution for Mid-Scale Pharmaceutical Production

The PTK PC-C Series Tablet Coater is a high-precision coating solution designed for mid-scale pharmaceutical production, featuring a flexible interchangeable coating pan system ranging from 4.0 liters to 28 liters. This modular design allows seamless scalability from R&D to small-batch production while minimizing equipment changes and process downtime.
Built on a chamber-type architecture, the PC-C Series integrates automated coating cycles, an integrated WIP cleaning system, a Watson-Marlow peristaltic pump, and a 21 CFR Part 11–compliant HMI. These features ensure consistent coating quality, efficient maintenance, and reliable process control in regulated pharmaceutical environments.

Optimized Design for Uniform Coating Performance

The PC-C Series is engineered to deliver uniform and reproducible coating results. A fully perforated side exhaust fan system optimizes airflow distribution throughout the coating chamber, contributing to reduced coating time and stable process conditions.

Anti-bearding Schlick spray nozzles provide consistent spray patterns and reliable atomization, while a unique baffle design promotes smooth tablet movement and uniform rotation inside the drum. This configuration minimizes tablet damage and enhances coating homogeneity.

One Platform from R&D to Mid-Scale Production

A key advantage of the PC-C Series is its interchangeable coating pan concept. Users can conduct formulation development and process optimization using smaller drums, then scale up production by simply changing the coating pan—without replacing the entire system.

The dedicated Coating Pan Change Device enables fast and safe pan replacement, significantly reducing downtime during capacity changes. This flexibility improves equipment utilization and supports a wide range of tablet coating requirements.

Advanced Control System for Regulatory Compliance

The PC-C Series is equipped with a 21 CFR Part 11–compliant HMI featuring recipe-driven software for real-time monitoring and control of critical process parameters. The system supports batch report generation, liquid volume prediction, and fully automated coating cycles, along with manual and automatic operation modes.

This advanced control architecture ensures process repeatability, data integrity, and effective compliance with pharmaceutical regulatory requirements.

Efficient Cleaning System and Optional Configurations

The integrated automatic and manual WIP cleaning system supports fast drying and efficient turnaround between batches. An air-operated liquid tank combined with the Watson-Marlow peristaltic pump ensures precise and stable coating solution delivery.

Optional configurations include HEPA-filtered inlet heat exchangers, inlet air dehumidifiers, and exhaust air dust extraction with HEPA filtration, helping maintain a clean and controlled production environment. The chamber-type design emphasizes ease of access and maintenance for long-term operational reliability.

Conclusion

The PTK PC-C Series Tablet Coater combines a flexible interchangeable pan system, automated and compliant control architecture, and a maintenance-focused chamber design into a single, scalable coating platform. It provides pharmaceutical manufacturers with a reliable solution for achieving consistent coating quality while supporting efficient scale-up and long-term productivity.
