[0002] Chemical fertilizers, referred to as fertilizers, are fertilizers made by chemical and physical methods that contain one or more nutrients required for the growth of crops. The macronutrients nitrogen, phosphorus, and potassium in the soil usually cannot meet the needs of crop growth, and chemical fertilizers containing nitrogen, phosphorus, and potassium are needed to supplement them.

[0003] Fertilizer production goes through raw material processing, fertilizer synthesis and then product processing, such as granulation, packaging and labeling. After granulation, the fertilizer still contains a lot of water and steam. If it is packaged directly, the fertilizer particles will condense into blocks or even change color, affecting the quality of the fertilizer. Secondly, the fertilizer may be easily affected by moisture due to the poor storage environment during storage. The problem of moisture or moisture in fertilizers is basically solved through the drying process. However, fertilizers often get damp or contain moisture in large quantities. When the existing drying equipment is used for drying, the drying is not thorough and uneven.

[0004] Therefore, it is necessary to develop a fertilizer drying device to solve the above problems. Utility Model Content
