Abstract
The application discloses a production method of expanded potassium dihydrogen phosphate, relates to the technical field of potassium dihydrogen phosphate production, and uses a production process of "neutralization-spray drying-secondary drying" to process, under the premise that energy consumption is controllable, produces expanded potassium dihydrogen phosphate products which can be quickly and completely dissolved in water, the water-soluble solution is clear, nozzles are not blocked, and the spraying efficiency is improved, through controlling the drying temperature, the generation of by-products (potassium polyphosphate) can be effectively prevented, therefore, the application has the advantages of simple production process, short process, suitability for large-scale use, green environmental protection, stable product quality, and the like, in addition, the obtained product is completely dissolved in water, has high clarity, is beneficial to spraying or unmanned aerial vehicle flying seeding, and thus the application efficiency is greatly improved.
