[0001] The utility model relates to the technical field of powder airflow drying, in particular to an airflow drying device. Background Art

[0002] Airflow drying is a method of drying granular solid materials by suspending them in an airflow and pneumatically conveying them. Currently, most airflow drying devices on the market heat and then accelerate the air flow inside the device to dry powder products. An existing airflow drying device for powder products (Announcement No.: CN221724844U) has at least the following drawbacks:

[0003] In practice, the drying process of materials in pneumatic drying equipment is primarily accomplished by the drying tube. The drying effect is determined by the hot air temperature and duration. The drying tube consists of a straight section and a pulse tube. Given a constant air volume, the drying time is determined by the length of the straight section and the pulse tube. To achieve optimal drying results, conventional pneumatic drying systems used a long drying tube, which increased the height of the drying workshop and capital investment. Utility Model Content
