Description

Technical Field

[0001] The utility model relates to the technical field of raw material drying, and more specifically to a drying device for potassium phosphate salt. Background Art

[0002] Phosphate is one of the natural ingredients of almost all foods and is widely used in food processing as an important food ingredient and functional additive. Phosphates used in food processing are usually sodium salts, calcium salts, potassium salts, and iron salts and zinc salts as nutritional enhancers. There are more than 30 types of commonly used food-grade phosphates, and sodium phosphate is the main type of food phosphate consumed in China.

[0003] In the process of producing phosphate, the raw materials of phosphate need to be dried. Drying of raw materials is an indispensable process. For example, a phosphate drying device with patent announcement number CN206906911U includes a material transfer platform and a main body shell. Fixed legs are welded under the material transfer platform, and a conveyor belt is laid on the upper surface of the material transfer platform. The phosphate drying device passes through the interior of the main body shell through the conveyor belt, so that the device does not need people to specially send phosphate into the drying device, saving manpower. The device is equipped with a heating pipe and a fan at the same time, which can dry the phosphate and blow the humid air out of the device, thereby achieving the purpose of drying the phosphate.

[0004] In actual use, the above drying device uses a conveyor belt to transport the raw materials to the inside of the device for drying. However, phosphates usually form a certain accumulation on the surface of the conveyor belt. Only using a heating fan to ventilate and heat the conveying surface will cause the raw materials accumulated at the bottom to not be fully dried, resulting in uneven drying and affecting the drying effect. Therefore, it is necessary to improve the shortcomings of the above equipment. Utility Model Content
