According to the requirements of material drying to be selected KJ-150-type hollow blade dryer 1 Taiwan
Paper sludge dryer works:
The hollow shaft is densely arranged with wedge-shaped hollow blades. The heat medium steam flows through the hollow shaft through the blades, and the heat transfer area in the effective volume of the unit is large. The heat transfer medium flows through the shell jacket and the hollow stirring shaft through the rotating joint, and the hollow stirring shaft has a different internal structure according to the type of the heat medium to ensure the best heat transfer effect.
In the blade and jacket heat medium access at the same time, the upper part of the discharge port at the same time dehumidification, which greatly increased the drying strength of the equipment. Evaporated moisture by the dehumidifier fan out of the dryer.
Equipment Features:
Blade dryer low energy consumption: As a result of indirect heating, do not carry a lot of air to carry heat, drying wall and set the insulation layer, so the heat loss is small.
Blade dryer low system cost: unit effective volume has a huge heat transfer surface, it shortens the processing time. Equipment size smaller, reducing the footprint.
Processing a wide range of materials: The use of different heat medium, both heat-sensitive materials, materials can be processed at high temperature.
Environmental pollution is small: carry the amount of air is very small, dust material entrainment rarely.
Low operating costs.
Stable operation: Due to the special compression-expansion stirring action of the wedge blade, the particles of the material fully contact with the heat transfer area. In the axial section, the temperature, humidity, mixing temperature and gradient of the material are very small, Stability.
