The hot air tangentially enters the bottom of the dryer and is driven by the agitator to form a powerful rotating wind field. The chlortetracycline material enters the dryer by the screw feeder. Under the strong action of the high-speed rotating stirring paddle, the material is dispersed under the action of impact, friction and shearing force, and the bulk material is rapidly pulverized and fully contacted with hot air. Heated and dried. The dehydrated dry material rises with the hot gas flow, and the classification ring intercepts the large particles. The small particles are discharged from the center of the ring to the outside of the dryer, and are recovered by the cyclone separator and the dust collector. The dry particles or the bulk material are subjected to centrifugal force to the wall. , fell to the bottom and was crushed and dried.
