Introduction
In microbial fertilizer production, preserving the activity of beneficial microorganisms during storage and application is critical. One of the most effective ways to improve the performance and longevity of microbial fertilizers is through granule coating technology. A professional fertilizer coating machine not only enhances product stability but also improves handling, appearance, and shelf life. If you’re looking to improve your biofertilizer quality and stand out in a competitive market, investing in a dedicated coating system is a smart move.
Why Microbial Fertilizers Need Coating
Microbial fertilizers contain living organisms like Bacillus, Azotobacter, or phosphate-solubilizing bacteria. These microbes are sensitive to environmental factors such as:
- Temperature fluctuations
- Moisture exposure
- Oxygen and UV light
Coating offers a protective barrier that helps:
- Prolong microbial viability
- Reduce moisture absorption
- Improve granule flowability and prevent caking
- Enable controlled-release capabilities
What Is a Fertilizer Coating Machine?
A fertilizer filming machine is designed to apply a thin layer of liquid or powder materials over the surface of granulated fertilizer. In microbial formulations, the coating layer often contains:
- Anti-caking agents (e.g. talc, kaolin)
- Moisture barriers (e.g. oil-based coatings)
- Secondary microbial additives (added post-granulation)
The machine typically includes:
- A rotary drum structure for continuous operation
- A liquid spray system for even coating
- Internal lining (often stainless steel) for hygiene and corrosion resistance
