Whether manufacturing high-end spherical confectionery or pharmaceutical sustained-release pellets (sugar spheres/non-pareils), achieving perfect sphericity and uniform particle size is a massive challenge. Traditional powder-layering methods are notoriously slow, labor-intensive, and prone to inconsistent shapes.
Recently, a manufacturer struggling with their 4mm spherical product line upgraded to JianPai’s JZB-B Centrifugal Granulator & Coater. The results were nothing short of a manufacturing revolution: batch times plummeted from 2 days to just 30 minutes, with the final yield soaring to 98%.
Here is a closer look at how this automated spheronization technology transformed their production.

TogglePrior to adopting JianPai technology, the client utilized a traditional manual dusting and panning process.
The Old Method: Operators had to repeatedly spray syrup and manually sprinkle fine sugar powder onto the core seeds.
The Bottleneck: Achieving a 4mm size required 12 distinct layers of manual powder dusting.
The Time Drain: A single batch took an exhausting 2 full days to complete.
Quality Issues: The yield was extremely low. The final pellets often suffered from irregular shapes, elliptical deformations, and rough, sharp edges rather than a perfect sphere.
To solve these critical inefficiencies, the client installed the JZB-B Centrifugal Granulator and Coating Machine. This advanced system combines five distinct processes into one machine: Seeding, Granule Amplification (Growth), Spheronization, and Coating.
By transitioning from a manual pan to a high-speed centrifugal rotor system, the entire production process became automated and seamlessly continuous.
For the 4mm spherical pellets, the JZB-B executes the following automated recipe:
| Phase | Process Parameters & Machine Action | The Result |
| 1. Seeding | Using fine powder as the raw material, atomized binder/syrup is sprayed while the centrifugal rotor spins at 200-300 RPM. | Generates perfectly uniform 0.5-1mm micro-mother pellets. |
| 2. Amplification | Continuous, automated spraying of liquid and synchronized powder feeding. The rotor speed is adjusted via VFD (Variable Frequency Drive). | Pellets grow rapidly and uniformly to the target 4mm size. |
| 3. Spheronization | High-speed rotor spinning combined with annular slit hot-air drying. | Surfaces become dense and smooth, achieving a Sphericity of ≥98%. |
The JianPai JZB-B is engineered not just for speed, but for absolute precision and compliance with global manufacturing standards (FDA/EU-GMP):
All-in-One Continuous Processing: What previously required 12 manual layers is now completed via a single, pre-programmed PLC recipe.
Absolute Sizing Precision: With independent VFD controls for the rotor, powder feeding pump, and liquid spray pump, the 4mm pellets achieve a strict size deviation of ≤0.1mm.
Visual Monitoring: The vertical, enclosed structure features a transparent observation window, allowing operators to monitor granule growth without stopping the machine or breaking the sterile environment.
Dust-Free & Clean-In-Place (CIP): Fully sealed operation eliminates airborne dust (crucial for operator safety and cross-contamination prevention). The integrated CIP system ensures rapid batch changeovers.
Safety Interlocks: Comprehensive mechanical and software safety interlocks protect both the operator and the batch.
The data from the client’s upgraded production line highlights a massive return on investment:
Production Time: Reduced from 48 hours to 30 minutes per batch.
Yield Rate: Skyrocketed to 98%.
Product Quality: Perfect Sphericity (≥98%), eliminating the rough edges and elliptical shapes of the past.
