Coating Pan for Pharmaceutical Tablet Coating Systems

Product Specifications

Technical details and manufacturing context for Coating Pan

Definition

The coating pan is a critical component within an automated pharmaceutical tablet coating system. It is a rotating vessel that holds tablets and facilitates the application of coating solutions. The pan is typically constructed from stainless steel 316L or food-grade polyurethane, materials chosen for their durability and compliance with pharmaceutical hygiene standards. The pan's internal diameter ranges from 800 to 2000 mm, and its working capacity varies from 50 to 500 liters, depending on the model. The rotation speed is adjustable between 2 and 20 rpm, and the pan can be tilted at an angle of 30 to 45 degrees to optimize tablet movement. The coating process involves loading tablets into the pan, which rotates to create a cascading motion. Coating solutions are atomized and sprayed onto the tumbling tablets at a rate of 0.5 to 5 L/min, while heated air at 40 to 80°C is introduced to facilitate drying. The drying air flow rate ranges from 1000 to 5000 m³/h. The motor power is between 1.5 and 7.5 kW, and the operating pressure for the spray system is 0.4 to 0.6 MPa. The supply voltage is 380 V, three-phase, 50/60 Hz, per IEC 60038. The noise level is ≤75 dB(A) at 1 m distance, measured according to ISO 3746. The machine weight varies from 800 to 3000 kg, depending on size and configuration. These parameters are reference ranges and must be verified for the specific model and application. The coating pan provides a controlled environment for uniform coating application, drying, and polishing of tablets, achieving desired release profiles, protection, and appearance. It is essential to confirm model-specific values and standards with the legal manufacturer or supplier before procurement or use.

Working Principle

Tablets are loaded into the rotating pan, which creates a cascading motion. Coating solutions are atomized and sprayed onto the tumbling tablets while heated air is introduced to facilitate drying. The rotation speed, spray rate, and temperature are precisely controlled to achieve uniform coating thickness. The pan's inclination angle and rotation speed are adjusted to ensure optimal tablet movement and coating distribution. The drying air temperature and flow rate are critical for efficient drying and to prevent over-wetting or sticking. The spray rate controls the coating thickness, and the operating pressure ensures proper atomization. The motor power drives the pan rotation, and the supply voltage must match the facility's electrical system. The noise level is monitored to ensure compliance with workplace safety standards. The coating process is continuous, with tablets tumbling and coating applied in layers until the desired thickness is achieved. The system is designed for batch processing, and the pan's capacity determines the batch size. Proper maintenance of the pan, including cleaning and inspection of the spray nozzles and air handling system, is essential for consistent performance.

Frequently Asked Questions

What materials are used for the coating pan?

The coating pan is typically made of stainless steel 316L or food-grade polyurethane. These materials are chosen for their durability and suitability for pharmaceutical applications. Always confirm the material grade with the manufacturer for your specific model.

What is the working capacity of the coating pan?

The working capacity ranges from 50 to 500 liters, depending on the model. This indicates the maximum volume of tablets the pan can process in a single batch. Verify the exact capacity for the specific pan you are considering.

How is the coating thickness controlled?

Coating thickness is controlled by adjusting the spray rate, which ranges from 0.5 to 5 L/min. The rotation speed and drying air temperature also influence the final coating. Precise control of these parameters ensures uniform coating thickness.

What standards apply to the coating pan?

The supply voltage is referenced to IEC 60038, and the noise level to ISO 3746. These standards are for verification purposes and do not imply certification. Always check compliance with the manufacturer.
