The indirect contact dryer is suitable for drying or cooling pastes, particles and powders in a slurry state. The special stirring blade features high heat transferring efficiency, providing a self-cleaning function.
Hollow chock shaped blades are fitted on the hollow shaft where the heat media flows through the blade. The temperature range of the blade dryer is -40 ℃ to 320 ℃.
Applications
The large heating area in the drying unit dries the material very fast and it is suitable for a wide variety of different industrial applications.

Features
1. The heat consumption of blade is low: It consumes 1.2 kg of steam to evaporate 1kg of water to dry slurry materials.
2. The cost of the blade dryer is low: Efficiency is high and processing time is shortened.
3. The wide range of materials can be processed: Heat sensitive material and the materials to be processed under high temperature might be processed by applying different heating sources.
4. Low pollution: solvents can be easily collected and recirculated, especially when operating in a closed system.
5. Steady operation: The material particles fully contact the heat transferring surface for uniform drying.
