Safe and Efficient Granulation Methods for Heat-Sensitive Food Additives

2026-06-04

1. Industry Challenges

Heat-sensitive food additives such as vitamins, enzyme powders, and flavorings are prone to degradation or evaporation during processing. Traditional wet granulation or high-temperature methods may reduce active components, affecting functionality and flavor.

2. Dry Granulation Technology Principle

Roller Compactor dry granulation mechanically compresses powder into high-density sheets, then cuts them into uniform granules. No water or high-temperature treatment is required, preserving heat-sensitive components. Adjustable roller gaps and hydraulic systems allow precise control of granule density and hardness.

3. Technical Advantages

Activity Preservation: Maximizes retention of heat-sensitive ingredient activity, ensuring functional integrity.
Uniform Granules: Cutting and secondary milling ensure consistent particle size, improving flowability and mixing uniformity.
Energy Efficient: No water or drying needed, reducing energy consumption and production cost.
Operational Safety: Excellent sealing prevents dust leakage, ensuring operator safety.

4. Application Examples

Dry granulation is suitable for nutritional powders, functional beverage premixes, and flavor blends. Optimized granules improve solubility, uniformity, and downstream processing performance, enabling efficient and stable production lines.

5. Conclusion

For food manufacturers, using dry granulation for heat-sensitive additives ensures activity and flavor preservation while increasing production efficiency—a key technique for achieving high-quality, controllable processing in the food industry
