Soda ash paddle dryer
FEATURES
1. Low energy consumption of paddle dryer: high thermal efficiency due to indirect heating
2. The paddle dryer has large heat transfer surface, which shortens the treatment time and improves the equipment size.
3. Wide range of materials: different media can be used to deal with heat sensitive materials and high temperature materials.
4. Common media are: steam, heat transfer oil, hot water, cooling water (when cooling). It can be operated continuously or intermittently, and can be used in many fields.
5. Less environmental pollution: the amount of air carried is small, and the dust material entrainment is small. Closed circuit circulation can be used for contaminated materials or solvent recovery.
6. Low operation cost: the equipment operates normally, only 1 person / day. Low speed mixing and reasonable structure. Small wear and tear, low maintenance costs.
7. Stable operation: due to the special compression expansion stirring effect of wedge blade, the material particle composition contacts with the heat transfer surface. In the axial range, the material temperature, humidity and mixing temperature gradient are very small, and the heat transfer coefficient is large.
WORKING PRINCIPLE
Wedge shaped hollow blades are densely arranged on the hollow shaft of the blade dryer, and the heat medium flows through the blade through the hollow shaft. The heat transfer area per unit effective volume is very large, and the temperature of heat medium ranges from - 40℃to 320℃. It can be steam or liquid, such as hot water, heat transfer oil, etc. Indirect conduction heating, without air to take away heat, heat is used to heat materials. The heat loss is only the heat dissipation to the environment through the insulation layer. The heat transfer surface of wedge blade has self-cleaning function. The relative movement of the material particles and the wedge-shaped surface produces a scrubbing effect, which can wash away the attached materials on the wedge-shaped surface and keep a clean heat transfer surface during operation.
