Fluidized Bed Spray Granulation Dryer

Product Description

Fluidized bed spray granulation dryer (abbr. as FSDG) ,which combines the technology of fluidized bed drying, spray drying and granulation, specializes in the direct drying and granulation of liquid material to granule products. The commercial set of FSGD features a large capacity, and finds its application usually in large-scale and continuous operation.

The liquid material is atomized by atomization nozzle, and dispersed onto the surface of fluidizing solid particles (which is called “seeds”) in the boiling-bed chamber. The seeds grow gradually in the mechanism of so-called coating or binding together. Through steps of spraying, granulation, drying and cooling, the granule product features with high bulk density, high particle strength, good sphericity, weak moisture absorption, and excellent flowability, which are adaptable for storage, transportation and applying by the downstream process.

The FSGD is the advanced high-tech product with several patent technologies self-developed by our company,so that its overall performance reaches top level of the world. The FSGD was listed into MSE Innovation Fund Project of National Ministry of Science and Technology (MOST, China), and passed the scientific and technological achievements appraisal in provincial and ministerial level. The FSGD was granted the Second Prize of Scientific and Technological Advance of China Petroleum and Chemical Industry Federation (CPCIF, China) in 2013, also listed into National Key New Product Plan Project of National Ministry of Science and Technology (MOST, China)in 2014.

Main Features

1. Specializing in the drying of solvent, suspensoid, paste liquid materials; granulating, drying and cooling in a single step inside fluidized bed, obtaining the dense granule products continuously.

2. Granule product features with high bulk density, high particle strength, good sphericity, weak moisture absorption, and excellent flowability, fulfill the demand of feed additive and fertilizer or other industries in mixing and application together with other material.

3. The single machine features of large production capacity, small size of equipment, excellent continuity and high degree of automatization.

4. The materials keep low temperature during the drying process, which is more suitable for heat sensitive materials, so that the vent will not cause second pollution.

5. Especially suitable for drying of slurry or paste materials featured as stickness, correspondingly the solid products are apt to absorbing moisture and caking.

6. Final products are mostly dense spherical granules with a narrow size distribution and good flowability.

7. The product has no fine powder,so that workplace has no dust flying.

8. With high evaporation intensity, the equipment has rather small size. Compared with the spray dryer, its main body size is only 1/10~1/20 under the same evaporation capacity.
