Spray Granulation Fluidized Bed Drying System

  • Spray Granulation Fluidized Bed Drying System

HVD-SGFD-P series spray fluid bed dryer granulator system is equipped with air pres by both the induced draft fan and the blower to make the material in a fluidized state. In the fluid bed granulation process, the material is stratified. The material with large particles is at the bottom of the granulation bed dryer, and the fine particles and dust are at the top of the dryer. The concentrated solution of dry materials is sprayed from the bottom or top and wrapped in fine particles and dust, making its volume and mass become larger. Because of the change in mass, the particles move downward. Driven by the heat energy provided by the hot air and the internal heating coil, the surface temperature of the wet material particles increases and the water evaporates. After evaporation, the particles from the humidity difference in internal and external, and the moisture gradually diffuses outwards, thus drying the material. The evaporated water vapor is mixed with unsaturated hot air and discharged by the cyclone. During the process of the cyclone, part of the fine particles and dust in the air is recovered and continue to participate in the granulation process. The dried material moves forward under the drive of the wind, and the granulation discharged from the discharge rotary valve. The system of spray fluidized bed granulation consists of feeding device, spraying granulation fluidized bed, finned heat exchanger, cooling dehumidifier, cyclone separator, bag dust collector, centrifugal fan, discharging device, crushing and screening device, finished product conveying system, electrical system, and automatic control system, etc.

Application of Spray Granulation Fluidized Bed Drying System

  • Fluid bed dryer granulator has high viscosity solution, such as pharmaceutical industry, fermentation industry, food industry, sewage treatment, environmental protection, etc.


  • Suitable for the mother liquor of amino acid fermentation, waste liquor of fermentation, chemical fertilizer, MSG, and other materials.

  • Used for processing paste, slurry, and other difficult-to-dry materials containing crystal water.

  • Widely used in continuous large-scale industrial production.


Features of Spray Granulation Fluidized Bed Drying System

  • Liquid materials can be coated, evaporated, dried, and cooled in the fluid bed dryer granulator to obtain the dried products.

  • High density, uniform moisture, high strength, good sphericity, not easy to absorb moisture, good fluidity, and other characteristics of dry products.

  • The product made of fluid bed dryer granulator is convenient for packaging, transportation, and storage; It is also easy to mix with other materials.

  • No dust, no peculiar smell, vacuum operation, and clean site environment during granulation and drying process.

  • Energy recycling and utilization, low energy consumption.
