ProCepT 4M8-TriX Coater for Pharmaceutical R&D

Overview

The ProCepT 4M8-TriX Coater is a precision-engineered laboratory-scale film coating system designed specifically for pharmaceutical formulation development and early-phase clinical batch manufacturing. It operates on the principle of pan coating—rotating a perforated drum to fluidize and uniformly expose solid dosage forms (tablets, capsules, or pellets) to atomized coating solutions while controlling temperature, airflow, and spray dynamics. Engineered for reproducibility and scalability, the system bridges the gap between benchtop feasibility studies and pilot-scale process transfer. Its modular architecture supports both aqueous and organic solvent-based formulations, with integrated thermal management, real-time process monitoring interfaces, and compliance-ready design elements essential for GLP- and GMP-aligned R&D environments.

Key Features

• Three-tiered drum volume configuration: 350 mL (R&D micro-batch), 1 L and 2 L (formulation optimization), plus optional 2 L / 5 L / 10 L drums for lab-scale scale-up studies.
• Adjustable drum rotation speed from 2 to 40 RPM, enabling precise control over particle motion, residence time, and film formation kinetics.
• Heated inlet air system with maximum temperature setpoint of 120 °C, supporting rapid solvent evaporation and thermally sensitive polymer curing protocols.
• Standard dual-fluid nozzle (0.7 mm orifice) delivering consistent atomization across variable viscosities; optional Schlick ABC anti-clogging nozzle available for suspensions containing insoluble excipients or high-solids content.
• Integrated wing-type baffles optimized for low-volume batches—ensuring uniform tablet tumbling, minimal attrition, and homogeneous coating distribution without over-mixing.
• Dedicated exhaust fan maintains negative pressure inside the drum chamber during operation, minimizing cross-contamination risk and improving operator safety.
• Removable fine-pore stainless-steel sieve insert (optional) enables reliable coating of mini-tablets and sub-2 mm multiparticulates with reduced loss through perforations.
• Multi-stage filtration system includes primary particulate filter and secondary activated carbon or HEPA-grade filter (solvent-specific), meeting occupational exposure limits (OELs) and environmental discharge requirements.

Sample Compatibility & Compliance

The 4M8-TriX Coater accommodates tablets (3–25 mm diameter), hard gelatin capsules (size 00–5), and multiparticulate systems (e.g., pellets, granules, beads ≥0.5 mm). Its construction adheres to ISO 9001-certified manufacturing standards, and all wetted parts are electropolished 316L stainless steel compliant with USP . The system supports audit trails, user access levels, and electronic signature functionality when integrated with validated third-party SCADA or MES platforms—facilitating alignment with FDA 21 CFR Part 11, EU Annex 11, and ICH Q5C/Q5D documentation expectations. Process parameters (RPM, inlet/outlet temperature, spray rate, airflow) are logged at ≤1-second intervals for full traceability.

Software & Data Management

While the base unit features analog/manual controls, the optional ProCepT Control Suite v3.2 provides PC-based supervisory control via Ethernet-connected PLC. It offers real-time graphing of critical process variables, automated recipe storage (with version history), deviation alerts, and CSV/Excel export of raw time-series data. All parameter changes are timestamped and attributed to user ID, satisfying ALCOA+ data integrity principles. Optional integration with LIMS or ERP systems enables seamless batch record generation and regulatory submission-ready reporting.

Applications

• Development and optimization of immediate-release, sustained-release, and enteric-coated formulations.
• Excipient compatibility screening under controlled thermal and mechanical stress conditions.
• Stability-indicating process validation for coating uniformity (assessed via content uniformity testing per USP or NIR mapping).
• Scale-down modeling for commercial coater qualification (e.g., correlating 2 L drum data with 600 L production equipment using dimensionless numbers such as Froude and Reynolds).
• Support for QbD initiatives—enabling DoE-driven studies on spray rate vs. film thickness, drum speed vs. weight gain variability, and inlet temperature vs. residual solvent profiles.

FAQ

What is the minimum batch size supported by the 350 mL drum?
The 350 mL drum is rated for batches as low as 50 g—ideal for high-value API screening where material conservation is critical.
Can the system handle ethanol-based coating solutions?
Yes—when equipped with explosion-proof motor options, solvent-rated seals, and activated carbon exhaust filtration, it complies with ATEX Zone 2 and OSHA 1910.107 requirements.
Is calibration documentation provided upon delivery?
Each unit ships with factory calibration certificates for temperature sensors (±0.5 °C accuracy), airflow meters (±3% FS), and rotational encoder (traceable to NIST standards).
How is cleaning validation supported?
The drum, baffles, and nozzle assembly are fully dismountable and compatible with standard CIP/SIP protocols; surface roughness (Ra ≤ 0.4 µm) ensures residue detectability per ICH Q5A.
Does ProCepT offer technical support for process troubleshooting?
Yes—remote diagnostics, on-site commissioning, and formulation consulting services are available through authorized regional application laboratories in Europe, North America, and APAC.
