From Powder to Granules: A Guide to Dry Granulation in the Chemical and Food Industries

2026-06-04

1. Industry Needs

The chemical and food industries have increasingly strict requirements for powder granulation. Uniform granules impact mixing performance, flowability, product quality, production efficiency, and downstream reaction stability.

2. Dry Granulation Principle

Dry granulation (Roller Compactor) mechanically compresses powder into high-density sheets, then cuts and mills them into granules. No water or high-temperature treatment is needed, protecting heat-sensitive materials. It is suitable for heat-sensitive chemicals, food additives, and functional nutrition powders.

3. Technical Advantages

Material Activity Preservation: Mechanical compaction prevents thermal degradation and loss of chemical components.
High Productivity: Suitable for large-scale production, with granule yield exceeding 85%.
Ease of Operation: Compact design, easy assembly and maintenance.
Granule Control: Adjustable roller gaps and hydraulic systems ensure uniform density and hardness.

4. Application Scenarios

Chemical raw materials: catalysts, fillers, composite additives
Food raw materials: functional nutrition powders, heat-sensitive flavor powders, seasoning powders
Optimized granules improve flowability and mixing uniformity, enabling stable operation of production lines.

5. Conclusion

Dry granulation technology offers an efficient, controllable, and safe solution for chemical and food industries, making it a key method to enhance productivity and quality in modern powder processing
