[0003] At present, the existing drying devices mostly use the form of drying machines blowing hot air to dry the raw materials. However, the hot air blown out will cause the temperature of the surface of the raw materials to rise rapidly, while the inside is still moist. This temperature difference between the inside and the outside will affect the drying effect and the drying will be uneven. In addition, when the dried materials are unloaded, they are easy to accumulate at the unloading port, which makes the unloading difficult and inconvenient to use, causing many troubles for people. Therefore, based on the above shortcomings, a chemical drug raw material drying device is now introduced to improve this. Utility Model Content
