JLB Series Fluid Bed Granulator & Coater (Top, Bottom & Tangential Spray)

The JLB Series Fluid Bed Granulator & Coating Machine is an advanced, multi-functional micro-particle processing system developed by Jianpai Tech. Featuring highly interchangeable process inserts, it seamlessly performs Top Spray (Granulation), Bottom Spray (Wurster Coating), and Tangential Spray (Pelleting) within a single machine.

Designed specifically for the pharmaceutical and food industries, this system is the ultimate solution for applying sustained-release, controlled-release, and enteric coatings onto powders, granules, matrix capsules, and micro-pellets.

Core Advantages & ROI

Precision Coating with Zero Material Loss

• Advanced Bottom Spray (Wurster) Technology: The material follows a highly controlled, fountain-like specific running trajectory. This ensures every single particle receives a perfectly uniform and continuous film coating, making it ideal for precision drug release profiles.

• Multi-Gun Constant Pressure Spraying: Equipped with a unique constant-pressure linear liquid spraying system (using 3 or more spray guns). This guarantees an ultra-stable flow rate, preventing droplet fluctuation and ensuring premium film quality.

• Short Spray Route & High Efficiency: The atomized mist particles have an incredibly short travel distance to the material bed. This maximizes coating efficiency, practically eliminates coating material loss, and significantly lowers your production costs.

• Excellent Dispersion (Zero Adhesion): Engineered with optimized aerodynamics (cylindrical acceleration and inverted-cone deceleration containers). The materials fluidize flawlessly without sticking, agglomerating, or adhering to the chamber walls.

• Ultimate Versatility: Whether you are processing highly porous instant granules, dense micro-pellets, or large particles, the JLB series adapts effortlessly to your formulation needs.

Working Principle

How Fluid Bed Granulation & Coating Works
The JLB Series transforms random powder fluidization into a highly regulated, cyclical flow.
Driven by a powerful, purified bottom-up airflow and gravitational forces, the materials inside the chamber form a continuous circulating loop—rising through the center and falling along the outer ring. Simultaneously, the binder or coating liquid is atomized and sprayed in the same direction as the airflow (co-current). This precise thermodynamic environment instantly dries the droplets upon contact, building a dense, flawless coating film or granulate structure layer by layer.

Application:

This equipment is suitable for multi-variety granulation, pellet coating, granulation of large particles, dense particles, porous instant granules, multi-component sustained-release controlled-release coating, spray drying and drying of powdered, granular, and agglomerated materials in the pharmaceutical and food industries.
