Case Study: How a Water-Soluble Fertilizer Manufacturer Tackles the Problem of Caking
2025-11-04
A high-end potassium nitrate fertilizer produced by a certain water-soluble fertilizer company often experiences severe caking during summer storage, leading to a sharp increase in customer complaints. After analysis by the technical team, it was found that the original anti-caking agent was unable to withstand the high-temperature and high-humidity conditions. The solution involves two key steps: First, optimizing the cooling process to ensure that the fertilizer temperature is sufficiently low before packaging. Second, replacing the original conventional mineral-oil-based anti-caking agent with a specialized polyether-siloxane composite anti-caking agent specifically designed for water-soluble fertilizers with high salt indices. This new product forms an ultra-thin yet highly durable hydrophobic film on the surface of the granules. Following implementation of these measures, the product demonstrated outstanding performance in both accelerated testing and actual storage conditions, with a significant reduction in the caking rate. 95% As a result, customer satisfaction has significantly improved, and the brand image has been further strengthened.
