Paddle dryer with honeycomb jacket shell, inside the pairs of hollow low-speed rotary shaft, the shaft is installed with wedge-type hollow heat transfer paddle, because of the wedge-shaped paddle on the material's strong extrusion and mixing effect, so that the paddle dryer has a higher than any other conduction dryer heat transfer efficiency, while the heat transfer surface has a very good self-cleaning effect, no scarring.
The residence time of the material can be adjusted by adjusting the feed rate speed, motor speed and so on, which can meet the adjustment range within a few hours. The material in the dryer is basically an overall unidirectional movement, no back mixing.
The heating medium of paddle dryer can be water vapor, thermal oil, hot water, molten salt and so on.
Product characteristics
Heat conduction drying mode, the thermal efficiency can reach more than 90%.
Because the shaft and paddle are hollow and can be passed into the heat source, the equipment unit volume heat transfer area is large.
The wedge-shaped structure of the stirring paddle has self-cleaning function, no fear of high viscous materials.
Less drying dust entrainment, exhaust gas can be condensed to recover solvents. Compact equipment, small volume, small footprint.
Compose double-stage drying with disk dryer to achieve better energy-saving effect and lower investment requirements.
Scope of application
Paddle dryer can be used for drying slurry, paste, granule, powder and other materials, especially for drying paste, high viscosity materials can get not bad drying effect.
