Raw material should be filtrated and then put into liquid tank in front of screw pump. One unit of three sides connector should be equipped before screw pump. One side of connector is connected with liquid tank, another side of connector is connected with cleaning water tank, in order to reduce exhaust air temperature when start heating the spray tower, and wash pump, pipes and atomizer after spray drying. Afterbeen filtered and heated(by steam heat exchanger and electrical heater) the air enters into the air distrbutor on the top of the dryer. The hot air enters into the drying room in the spiral form and uniformly. Passing through the high-speed centrifugal atomizer on top of the tower, the material liquid will rotate and be sprayed into the extremely fine mist liquid beads. Through the very short time of contacting the heated air, the materials can be dried into the final products. The final products will be discharged continuously from the bottom of the drying tower and from the cyclones. The waste gas will be discharged from blower before deep filtrating by bag filter. All of the powder from spray tower , cyclone and bag filter is collected and transferred by dehumidified air through air transfer system. Final powder is collected by small cyclone.
