This invention discloses a supersonic drying system and dehydration method for particles, relating to the field of particle drying technology. The system includes a collection cylinder fitted outside an accelerating cylinder. By guiding thermosensitive polymer particles into a vortex flow field, they are suspended and spirally ascended under the dynamic balance of centrifugal force and airflow drag. The low-pressure environment generated by the vortex flow field lowers the boiling point of water on the particle surface, and combined with a heat-generating unit, moisture evaporation can be achieved at a relatively low temperature. Subsequently, a high-energy electron beam excited by a plasma generator promotes the migration and evaporation of moisture from the particles, enhancing the drying effect. After dehydration, the particles automatically detach from the vortex flow field due to density changes and enter the collection zone, while the nitrogen flow carries the evaporated water vapor into the discharge zone, achieving automatic separation of the particles and the nitrogen flow. This invention, through its unique structural design and particle motion drying process, is suitable for thermosensitive polymer particles, avoiding thermal degradation and achieving highly efficient particle drying.
