[0002] Urea, also known as carbamide, is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal. As a neutral fertilizer, urea is suitable for all kinds of soils and plants. It is easy to store, easy to use, and has little destructive effect on the soil. It is a chemical nitrogen fertilizer with a large usage and the highest nitrogen content.

[0003] At present, in the production process of urea, the urea melted into a slurry, i.e., urea liquid, needs to be sprayed and cooled into fertilizer granules. That is, the slurry is sprayed downward from the top of the granulator, and then cooled into granules after falling naturally. In order to prevent urea from agglomerating, the urea needs to be dried and purged later. However, since the urea granules are light in weight, they are easily scattered everywhere during drying and purging, which is not convenient for drying. At the same time, the temperature of the dried urea granules is high. In order to avoid burns to workers, they need to be bagged after they have cooled naturally, which reduces work efficiency.
