The Problem

Traditionally, research and development units in pharmaceutical companies were constrained by the limitations of existing coating facilities. This forced them to manufacture unnecessarily large quantities of test drugs, resulting in significant waste of effort and resources.

The Solution

The Fluidized Bed Processor is designed to address this specific challenge by offering a unique standard for handling small batches of pellets. It ensures that the quantity of the test batch never exceeds your requirements, reducing waste and improving efficiency.

Key Benefits

  • Versatile Coating: Capable of handling both aqueous and organic film coating systems.
  • Portability: Extremely portable for ease of use and mobility.
  • Advanced Control Panel: Allows for monitoring and recording of all settings for the Fluid Bed Processor.

Components and Features

Coating Cylinder/Container/Bowl

  • Central cylindrical portion made of SS-316 quality material.
  • Glass cylinder for easy viewing during the coating process.


  • Heats the inlet air to the desired temperature required for drying pellets.
  • Temperature can be controlled from ambient to 90°C.

Exhaust Pipe

  • Clears unwanted fumes and dust generated during the coating process.

Spray Gun

  • Designed for top and bottom spray coating.
  • Utilizes SS-316 nozzles and peristaltic pumps for precise dosing.
  • Adjustable for droplet size depending on the viscosity of the solution.

Control Panel

  • 4-inch Touch Screen PLC-based advanced control panel for comprehensive control.

Peristaltic Pump

  • Delivers an exact amount of solution to the spray gun through a silicone pipe.


Bottom-Spray Coating (Wurster Coating)

  • Uses energy to create a pneumatic mass transport, ensuring uniform coating.
  • Ideal for coating small particles with high coating quality.
  • Prevents premature viscosity changes of the coating droplet.

Top-Spray Coating

  • Suitable for both batch and continuous operations.
  • Ensures good spreadability and quality coating.
