Fluidized Bed Pelletizer

▪ DWY Series Multifunctional Pelletizing Coater is a multifunctional fluid bed equipment that integrates pelletizing and coating with tangent spray, coating with bottom spray and granulating with top spray.

        ▪ High efficiency and reduce the cost of material for coating.

        ▪ Combine multifunctions of pelletizing, granulating, coating ,mixing and drying, reduce steps of techniques,process of contamination, and the degree of labor.

        ▪ Tangent spray technique：pelletizing, covering, coating

        ▪ Top spray technique：granulating

        ▪ Bottom spray technique：coating

        ▪ Tangent spray technique： the material on the fluid bed is pushed upward by the hot air flow, it will do regular spin rolling movement in the specially designed container with the influences of centrifugation of the rotary plate, centripetal force of material container, the air flow back and the gravity. The liquid sprayed at a tangent direction make the material into core of pills, which are coated by powder from tangent sprayer to get required tighten fine pellets.

        ▪ Top spray technique： the material on the fluid bed forms upward. Flowing state pushed by the hot air flow, then combined into granules gradually by the liquid sprayed from upward, and irregular granules will be gotten after drying.

        ▪ Bottom spray technique：the material is pushed upward from the bottom of the flow leading tube by hot air flow and sprayed back, and coating liquid is sprayed from bottom of the flow leading tube ,and coated onto the materials moving in the same direction to achieve the coating purpose.
