The caking problem of urea-based triple compound fertilizers
Thread Content
A new system uses drum granulation with urea as the main nitrogen source. The products often form lumps during storage shortly after production; although these lumps can be broken up by turning the bags over, how can this problem be controlled at its source? I would appreciate some guidance from experts
Three factors for caking: moisture, temperature, and pile height. Other measures: Add urine-based anti-caking accelerator.
Improve the production process by primarily reducing the moisture content of the products, as well as the temperature during packaging, the storage temperature, and the stacking height. A more effective method is to use anti-caking agents to form a hydrophobic film on the surface of the fertilizer particles.
I’d like to ask the brother upstairs again: what are some of the brands of anti-caking agents that work well at present? Thank you!
Since the production processes and product characteristics vary from one factory to another, and there are many different reasons for caking… the anti-caking agents that work well for some manufacturers may not be effective for others. At present, there are no standards for anti-caking agents, nor is it possible to test them; the best approach is to conduct experiments in actual production. The most widely used anti-caking agents at present are oily coating oils and powdered anti-caking agents. Powdered anti-caking agents are a product that has been developed in recent years, and they are gradually replacing coating oils, as the use of coating oils is more complicated and costly. There are quite a number of manufacturers of anti-caking agents in Beijing, Shanghai, and Shandong.
