[0002] Spray drying is a method of applying systematic technology to material drying. In the drying chamber, after the dilute material is atomized, in contact with hot air, the moisture is quickly vaporized to obtain a dried product. This method can directly dry solutions and emulsions into powdery or granular products, and can omit processes such as evaporation and crushing.
[0003] At present, during the use of the spray drying device, large-particle materials in the feed liquid are likely to block at the atomizing nozzle, often requiring cleaning. At the same time, it will also cause greater wear on the atomizing nozzle, affecting the service life of the atomizing nozzle. For this reason, we propose a spray drying device with a filtering device. Content of the Utility Model

It solves the problem that during the use of the current spray drying device, large-particle materials in the feed liquid are likely to block at the atomizing nozzle, often requiring cleaning, and at the same time, it will also cause greater wear on the atomizing nozzle, affecting the service life of the atomizing nozzle.
