[0002] Chemical fertilizers are referred to as chemical fertilizers. They are made by chemical or physical methods and contain one or more nutrients required for the growth of crops. They are also called inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc. In the process of fertilizer production and processing, wet materials need to be blended and then granulated. Since the granulated fertilizer has a certain humidity, a drying device is required to dry the granular fertilizer.

[0003] The patent with publication number CN218155214U proposes a fertilizer drying device for compound fertilizer production. When the cylinder rotates, the fertilizer is constantly turned inside, which makes the drying more uniform and less likely to pile up, thereby improving the drying efficiency. However, the drying device is the same as the existing drying device. It is necessary to add a certain amount of fertilizer into the drying device first, and then discharge the fertilizer after the drying is completed. The fertilizer cannot be dried continuously, and the drying efficiency needs to be further improved. Secondly, the drying device uses electric heating to dry like the existing drying device, and the power consumption is relatively high, which increases the production cost of the enterprise. Therefore, the utility model proposes a drying device for fertilizer production. Utility Model Content
