1、 Working principle of XSG series rotary flash evaporation

The XSG series rotary flash dryer is a practical product developed and designed by our company by digesting and absorbing advanced drying technology from abroad and combining it with the actual situation of domestic drying technology and crushing process.

After being heated, the air enters the flash evaporation main tower tangentially through the bottom air inlet of the host, forming a high-speed rotating airflow similar to a tornado inside the main tower. At the same time, the size of the bottom annular gap is adjusted according to different material properties to maintain a relatively suitable wind speed. The material is directly fed into the drying tower through a spiral feeder, and under the impact and driving of high-speed airflow, it quickly disperses and rotates at high speed with the airflow. For relatively large and humid particle clusters, high-speed airflow is not enough to break them and rotate them at high speed, so they gradually fall under the action of gravity. When they fall to the bottom of the host, they are forcibly broken and micronized by the crushing device set at the bottom, and then rotate and rise together with the high-speed airflow to complete the drying process. In order to achieve an extremely low final moisture content of the material without being affected by fluctuations in initial moisture and affecting product quality, cyclone blades are installed in the drying tower to form a relatively stable fluidized bed. At the same time, the cyclone blades also play a role in ensuring the necessary residence time and classification for drying.
