Coating Pan for Pharmaceutical Tablet Coating


A coating pan, often referred to as a conventional coating pan, is a widely used machine in pharmaceutical manufacturing for applying sugar, film, and protective coatings to tablets and pellets. As described in standard pharmaceutical engineering texts, the conventional system consists of a rotating stainless steel pan mounted at an angle, which allows tablets to tumble continuously while the coating solution is applied and dried.

The machine is built on a rigid MS structure with stainless steel cladding to ensure durability, hygiene, and compliance with cGMP requirements. The SS coating pan is enclosed within a cleanable housing and supported on vibration-damping mounts so that no foundation is required. The airflow system includes filters and controlled heating, ensuring uniform drying—an essential principle noted in tablet coating technology.

In accordance with typical safety features mentioned in pharmaceutical equipment manuals, the electrical system includes an interlock that allows the heaters to operate only when the blower is running, preventing overheating. The mouth ring of the pan is seamlessly soldered to avoid dead spaces and contamination risks. High-quality components such as helical gear drives, induction motors, and branded electrical controls are used for reliable operation. Optional features such as thermostat temperature control and flameproof or explosion-proof assemblies are available when required.

Coating pans are used across pharmaceutical, nutraceutical, confectionery, and food industries. They are available in a wide range of sizes—from 8-inch laboratory coating pans to 48-inch industrial coating pans—making them suitable for both R&D and production-scale operations. Their simple construction, ease of cleaning, and adherence to coating principles make them one of the most dependable machines for conventional coating applications.

Salient Features of Coating Pan

  • cGMP-Compliant Mechanical Design: The coating pan assembly adheres to Current Good Manufacturing Practices, with hygienic construction and smooth finishes to ensure safe pharmaceutical processing.
  • High-Grade Stainless Steel Construction (AISI 316/304): All product-contact components are manufactured from AISI 316 stainless steel for corrosion resistance, while non-contact parts use AISI 304 as recommended in pharmaceutical equipment standards.
  • Rigid Fabricated Structure with SS Enclosure: The machine is built on a robust MS frame covered with stainless steel cladding, providing a cleanable exterior surface and structural stability during continuous operation.
  • Vibration-Free Operation Using Anti-Vibration Mounts: The pan and drive assembly are mounted on industrial-grade anti-vibration pads, eliminating the need for fixed foundation and reducing mechanical stress.
  • Hot Air System with Controlled Heating: Equipped with a movable hot-air blowing arrangement using electric heaters to ensure uniform drying—an essential requirement highlighted in standard coating process literature.
  • Optimized Tablet Movement and Mixing: Welded baffles inside the pan enhance tablet cascading and rolling motion, promoting uniform distribution of coating material.
  • Efficient and Uniform Coating Performance: The design allows complete wetting, spreading, and drying cycles, achieving consistent coating quality across different batch sizes.
  • Adjustable Pan Angle for Process Flexibility: The inclination of the pan can be varied to suit coating requirements, improving bed movement and drying efficiency as discussed in tablet coating principles.
  • Interchangeable Pans for Variable Capacities: Multiple pan sizes can be fitted on the same drive assembly, enabling both laboratory-scale and production-scale operations with a single machine.
  • Documentation Support (IQ/OQ): Installation and Operational Qualification documentation can be provided to support regulatory validation and compliance with pharmaceutical quality systems.

Optional Accessories of Coating Pan

  • Interchange different size Pan
  • Atomized Spraying system with Spray Gun, Peristaltic Pump and Solution tank
  • Quick dismantle & adjustment of spray guns
