A New Type of Draft Tube, Spout Fluid Bed Particle Coater

RPI ID: 2007-017-601

Innovation Summary:
This invention introduces a method for coating particulate materials using a fluidized bed system combined with a controlled spray mechanism. The process ensures uniform coating thickness while minimizing particle agglomeration. It supports scalable, continuous operation and is compatible with a wide range of materials. The technology is particularly suited for pharmaceutical, agricultural, and advanced materials applications.

Challenges / Opportunities:
Achieving consistent, uniform coatings on fine particles is a persistent challenge across multiple industries. Traditional coating methods often result in uneven distribution or clumping. This invention addresses these limitations through a precisely controlled fluidized bed process. It opens new opportunities in drug delivery systems, seed treatment technologies, and functional material development.

Key Benefits / Advantages:
✔ Uniform coating distribution
✔ Reduced agglomeration
✔ Scalable and continuous processing
✔ Compatible with diverse particulate materials

Applications:
• Pharmaceuticals
• Agriculture (e.g., seed coatings)
• Catalysts
• Functional powders
