A Pharmaceutical Auto Coater is an automatic tablet coating apparatus for depositing film or sugar coatings on tablets, capsules, or pellets. It provides a uniform coating, controlled process, and high efficiency, and therefore, it forms an essential tool in contemporary pharmaceutical production.

Technical Specifications of Auto Coater

1. Material of Construction

Stainless Steel (SS 316L for product contact surfaces, SS 304 for non-contact surfaces) – maintains strength and GMP and FDA compliance.

Perforated or Non-Perforated Coating Pan – facilitates the even spread of coating solution.

Mirror/Matte Finish – makes cleaning easy and avoids contamination.

2. Coating Pan & Capacity

Pan Capacity: From 5 kg to 1000 kg per batch.

Pan Speed: Adjustable 3–30 RPM according to coating needs.

Perforation Size: 1–3 mm (for effective drying).

3. Spray System

Gun Type: HVLP (High Volume Low Pressure) Spray Guns for uniform atomization.

Number of Spray Guns: Usually 2–8 guns depending on pan size.

Spray Nozzle Size: 0.5–1.5 mm for accuracy coating.

Pumping System: Peristaltic Pump for precise and controlled liquid flow.

4. Air Handling System

HEPA Filters (H13 or H14) for Air Inlet – eliminates airborne pollutants.

Dehumidification System (Optional) – ensures humidity control for moisture-sensitive formulas.

Exhaust Blower Capacity: 200–2,000 CFM, for effective drying.

5. Drying System

Hot Air Blower: 5–30 kW heat system for fast drying.

Temperature Control Range: 25°C to 80°C, for maximum drying without degradation.

6. Control System

PLC-Based HMI Touchscreen Panel – automates and controls coating parameters.

Real-Time Monitoring: Regulates spray rate, air pressure, pan speed, and temperature.

Recipe Storage: Stores multiple formulations for easy batch processing.

7. Safety Features

Automatic Spray Gun Cleaning System – avoids clogging.

Interlock System – inhibits operation when the door is open.

Explosion-Proof Motor (For Solvent-Based Coating) – provides protection in hazardous environments.

Applications of Auto Coater in the Pharmaceutical Industry

Film Coating of Tablets & Pellets

Improves tablet appearance, taste masking, and enhances stability.

Normal coatings: HPMC, PVA, and Acrylic-based coatings.

Enteric Coating

Preserves tablets from stomach acid and facilitates drug release in the intestine.

Applied to proton pump inhibitors (PPIs) and NSAIDs.

Sugar Coating

Traditional coating for use in taste masking and palatability enhancement.

Used in vitamins, pediatrics, and nutraceutical applications.

Controlled Release & Modified Release Coatings

Contributes extended-release (ER), delayed-release (DR), or sustained-release (SR) functionality.

Moisture & Light Protection

Preserves sensitive drugs from external influences such as humidity, light, and oxidation.

Tablet Branding & Identification

Colorful coatings facilitate brand distinction and counterfeit deterrents.
