Characteristics of Hollow Blade Dryer:
1. It is low in energy consumption. Air and heat is not carried away in big volume due to indirect heating.
2.The outer wall of the hollow blade dryer is provided with a thermal insulation coat. Only a little heat is needed for evaporating 1kg water of slurry materials.
3. The blade dryer system is low in cost. It has huge heat transmission area within unit effective volume, thus shortening processing time. Equipment varies little in size, thus greatly reducing building area and building space.

4. Wide scope of application: With adoption of different heat media, both thermo-sensitive materials and high-temperature materials can be treated. Common media include: water steam, heat conduction oil, hot water and cooling water, etc. It can be operated either continually or intermittently, and can be applied in many fields.
5. Small environmental pollution: Carried air is not used so little powder material is entrained. Material
solvent evaporation is small so it is easily treated. Close loop circulation may be adopted for polluted material or recyclable solvent.
Low operation cost: Only 1h/day*person is needed for normal operation. Low-speed mixing and reasonable structure. Small wear and low maintenance cost.
Stable operation: Under special compression-expansion mixing of wedge blade, the material particle contacts with the heat transmission surface sufficiently. Within an axial interval, the gradient in temperature, humidity and degree of mixing is small, thus guaranteeing stability.
