Overview
Large heat area in a small body
The KJG hollow blade dryer indirectly heats or cools paste, granule, powder and slurry. It can complete drying, cooling, heating, sterilizing, reacting and low temperature combustion.
Wedge-shaped hollow blades are densely arranged on a hollow shaft, and the heating or cooling medium flows through them. The wedge surface cleans itself as the material moves across it.
Heat
The medium flows through the hollow shaft and blades. The medium temperature can run from -40 ℃ to 320 ℃.
Stir
The blades push and release the material, so it keeps contact with the heat transfer surface.
Self-clean
The sliding material scrubs the wedge surface, so the heat transfer surface stays clean.

Features
Low energy use, stable operation
Indirect heating needs no carrying air, so little heat is lost.
- 01
Low energy use
Indirect heating needs no large flow of carrying air. With the insulated shell, evaporating 1 kg of water from slurry needs only 1.2 kg of steam.
- 02
Compact
The heat transfer surface per unit volume is large, which shortens the processing time and reduces the size of the equipment.
- 03
Wide range of material
Different heat media suit heat-sensitive material and material that needs high temperature. Common media are steam, thermal oil, hot water and cooling water.
- 04
Continuous or batch
It can run continuously or intermittently.
- 05
Clean running
No carrying air means very little dust is carried out. A closed loop can be used for contaminated material or solvent recovery.
- 06
Low wear
Low wear and low maintenance cost, with stable operation from the compression and expansion stirring of the wedge blades.

Questions
Before you order
01What can the hollow blade dryer do?
It indirectly heats or cools paste, granule, powder and slurry. It dries, cools, heats, sterilizes, reacts and burns at low temperature.
02Why is the energy use low?
Heating is indirect, so no carrying air takes the heat away, and the outer wall is insulated. For slurry, evaporating 1 kg of water needs only 1.2 kg of steam.
03How does the blade stay clean?
The wedge-shaped blade surface cleans itself. The moving material scrubs away anything that sticks.
04Which heat media can I use?
Steam, thermal oil, hot water and cooling water. The medium temperature can run from -40 ℃ to 320 ℃.
05Can it run non-stop?
Yes. It can be operated continuously or intermittently.
