Yacheng / PILOTECH YC-610 Laboratory High-Efficiency Film Coating Machine for Tablets, Capsules, Film Coats, and Enteric Coats

Overview

The Yacheng / PILOTECH YC-610 is a precision-engineered laboratory-scale film coating machine designed for R&D, formulation optimization, and small-batch GMP-compliant coating trials of solid oral dosage forms. It operates on the principle of fluidized-bed-assisted pan coating—combining controlled rotational motion of a perforated, baffled drum with precisely metered atomized spray application and regulated negative-pressure hot-air drying. This integrated process ensures uniform deposition of aqueous or organic polymer solutions (e.g., HPMC, Eudragit® series, cellulose acetate phthalate) onto tablets, capsules, mini-tablets, and multiparticulates—enabling reproducible development of immediate-release film coats, functional barrier layers, and pH-dependent enteric coatings. The system is engineered for scalability from lab to pilot scale, supporting critical early-phase pharmaceutical process understanding per ICH Q5A and Q8(R2) guidelines.

Key Features

• 7-inch color touchscreen HMI with intuitive PLC-based interface for real-time monitoring and adjustment of all critical process parameters—including inlet air temperature, pan surface temperature, fan frequency, atomization pressure, nozzle needle stroke timing, pan rotation speed, and peristaltic feed rate.
• Modular, customizable coating pan design (standard φ210 mm; optional diameters available) with Z-pattern baffle configuration to enforce extended, laminar tumbling trajectories—enhancing particle exposure homogeneity and reducing segregation risks.
• Advanced dual-function spray nozzle with adjustable fan-angle pneumatic actuation, integrated anti-clogging needle mechanism (stroke frequency programmable via HMI), and closed-loop atomization pressure control: automatic peristaltic pump shutdown triggers if pressure falls outside user-defined limits—preventing drips and ensuring coating consistency.
• Optimized airflow architecture featuring conical inlet and outlet ducts (wind hoods) to maximize thermal exchange efficiency across the bed layer while maintaining stable negative-pressure conditions (−15 to −25 Pa typical)—critical for solvent evaporation kinetics and film integrity.
• Dedicated micro-tablet coating kit option (optional accessory) with reduced-diameter pan and high-sensitivity airflow calibration—validated for sub-3 mm cores where conventional tumbling dynamics risk attrition or incomplete coverage.
• Low-slip, hydrodynamic impeller geometry prevents tablet adhesion to pan walls during rotation—minimizing mechanical stress and preserving core integrity throughout coating cycles.

Sample Compatibility & Compliance

The YC-610 accommodates a broad spectrum of solid dosage forms: standard and scored tablets (4–12 mm), hard gelatin and HPMC capsules (size 00–5), sugar-coated pellets, and mini-tablets (≥1.5 mm). Its sealed, stainless-steel (316L contact surfaces) construction meets ISO 14644-1 Class 7 cleanroom compatibility requirements. Process data logging—including timestamped parameter histories, alarm events, and operator actions—is compliant with ALCOA+ principles. When configured with audit-trail-enabled firmware and electronic signature modules, the system supports FDA 21 CFR Part 11 readiness and GLP/GMP documentation workflows. All materials contacting product conform to USP <661.1> and EP 3.1.1 standards.

Software & Data Management

The embedded PLC controller logs all operational variables at 1-second intervals to internal non-volatile memory (≥10,000-cycle retention). Export is supported via USB port in CSV format for integration with LIMS or statistical process control (SPC) platforms such as JMP or Minitab. Optional Ethernet/IP or Modbus TCP communication enables remote supervision and centralized data aggregation in multi-unit laboratories. Batch reports include full parameter traceability, deviation flags (e.g., pressure excursions, temperature drift >±2°C), and digital signatures for QA sign-off—fully aligned with Annex 11 and EU GMP Annex 15 expectations.

Applications

• Formulation screening of film-coating polymers, plasticizers, and opacifiers under controlled humidity and thermal profiles.
• Enteric coating development using pH-responsive resins (e.g., Eudragit L100/S100), including dissolution profile correlation studies per USP <711>.
• Stability-indicating process validation for coating thickness uniformity (measured via cross-sectional SEM or near-infrared chemical imaging).
• Scale-down modeling for commercial pan coaters—leveraging dimensionless numbers (Froude, Reynolds) to maintain dynamic similarity in particle motion and heat/mass transfer.
• Regulatory filing support: generation of representative batches for ANDA, DMF, or CMC sections requiring demonstration of coating robustness and reproducibility.

FAQ

What batch sizes does the YC-610 support?

Standard operation ranges from 100 g to 400 g of tablets or capsules per batch, with validated performance across this span. Custom pan configurations extend lower-range capability to 50 g for high-value APIs.

Is the system suitable for organic solvent-based coatings?

Yes—equipped with explosion-proof motor options and ATEX-compliant ventilation routing (optional), it supports ethanol-, acetone-, or isopropanol-based systems when paired with appropriate exhaust scrubbing.

Can process parameters be exported for regulatory submission?

All raw sensor data, setpoints, alarms, and operator inputs are time-stamped and exportable in CSV or PDF report formats—with optional digital signature and audit trail activation for Part 11 compliance.

Does the YC-610 meet GMP requirements for preclinical batch production?

When operated with documented SOPs, calibrated instruments, and qualified cleaning procedures, it fulfills GMP expectations for non-commercial clinical trial material manufacturing per ICH GCP and WHO TRS 986 Annex 2.

How is coating uniformity verified on this system?

Uniformity is assessed post-coating via weight gain distribution (RSD ≤3.0%), content uniformity testing (USP <905>), and optional in-line NIR monitoring (add-on module) for real-time spectral mapping of coating thickness gradients.
