JZB-B Series Centrifugal Granulating Coating Machine

Model

The JZB-380 is our highly precise lab-scale centrifugal granulator, designed for a batch capacity of 0.5kg to 5kg. It is the perfect R&D instrument for formulation scientists to develop and test seed generation, spheronization, and coating parameters before scaling up to commercial production.

With a production capacity of 10kg to 20kg per batch, the JZB-700 serves as an excellent pilot-scale rotor granulator. It provides pharmaceutical facilities with a reliable platform for small-batch clinical manufacturing and seamless process scale-up, ensuring perfectly spherical pellets every time.

The JZB-1000 is a robust commercial-scale centrifugal coater and granulator, capable of processing 30kg to 50kg per batch. Driven by a 5.5Kw turntable motor and precise VFD controls, it is the standard workhorse for mid-sized pharmaceutical plants requiring continuous, dust-free pellet production.

Engineered for high-throughput manufacturing, the JZB-1200 handles an impressive 60kg to 90kg per batch. This heavy-duty spheronizer maximizes daily output for large pharmaceutical operations, delivering rapid granulation speeds and highly uniform pellet sizes with zero material loss.

As the flagship mega-capacity model of the series, the JZB-1500 boasts a massive production capacity of 100kg to 140kg per batch. Equipped with a powerful 15Kw main motor, it is tailor-made for global pharmaceutical conglomerates demanding maximum pelletizing throughput, ultimate reliability, and strict cGMP compliance.

The JZB-B Series Centrifugal Granulating & Coating Machine (also known as a Rotor Granulator or Spheronizer) is a highly advanced, all-in-one system designed for the pharmaceutical and food industries.

It ingeniously integrates three core functions into a single machine: Seed Core Generation, Spheronization (Granulation), and Film/Powder Coating. Driven by centrifugal force, friction, and airflow, this equipment is the ultimate solution for producing perfectly spherical, dense, and uniform pellets (micro-pills) with zero dust emission.

Core Advantages & ROI

3-in-1 Functionality for Perfect Spherical Pellets

Extremely High Sphericity: Achieves a perfectly round, dense, and smooth surface for every pellet. The granule size is highly uniform, ensuring excellent product stability and a near 100% qualified rate.
True 3-in-1 Process: Eliminates the need to transfer materials between different machines. From making the initial seed core to building the pellet size and applying the final coating, everything is done in one enclosed rotor system.
Smart VFD Control: The turntable speed, powder dosing, and liquid spray rate are all controlled by Variable Frequency Drives (VFD) via a user-friendly HMI touch screen, allowing for precise and flexible recipe management.
Zero Dust & cGMP Compliant: Features a fully enclosed operation. The optimized airflow system ensures dust-free processing, prevents material loss, and allows for automatic cleaning and drying, fully meeting strict cGMP standards.

Working Principle

The Centrifugal Tumbling & Layering Process
The magic of the JZB-B lies in its unique rotor dynamics:

Tumbling & Fluidization: Powder or seed cores are placed on the spinning centrifugal turntable. The combination of centrifugal force, friction, and a controlled slit-airflow creates a highly efficient “spiral-rope” tumbling motion.
Layer-by-Layer Growth (Spheronization): As the particles tumble, the spray gun atomizes the liquid binder while the feeder synchronously supplies fine powder. The powder adheres to the wet surface of the tumbling cores, building up the pellet diameter layer by layer in a highly spherical shape.
Simultaneous Drying & Coating: Hot air is continuously blown through the annular gap, drying the pellets as they form. Finally, atomized coating liquids can be applied to the same tumbling bed to create a solid, smooth, and controlled-release film.
