Electroplating sewage sludge mud pyrite food waste residue thermal efficiency increased by 30% Hollow Paddle Dryer

1. Blanking dryer low energy consumption: due to indirect heating, there is no large amount of heat taken away with the air, the dryer wall is installed the insulation layer, save more energy than the usual convection drying method.

2. Hollow paddle dryer system cost is low: the unit effective volume has a huge heat transfer surface, to shorten the processing time, equipment size becomes smaller, it greatly reduces the building area and building space.
3. Wide variety of process problems can be solved by using any kinds of heating source. It is specially suitable for drying heat sensitive materials and ligh temporature materials.The normal heat transfer medium can be steam, heat transfer oil, hot water, as well as cooling water etc... The dryer can be used for continuous or batch processing. It has been widely used in many industry areas already.
4. Small environmental pollution: do not use air with dust material. Material solvent evaporation is very small, easy to handle. For the pollution of the material or the need to recover the solvent conditions, can be used closed circuit.
5. Low operating costs: normal operation of the device, only 1 hour/day. Low-speed mixing and reasonable structure. Wear rate is very low, and maintenance costs are also very low.
6. Stable operating continuously: Because of the special compression and inflation of agitation function of paddle dryer, the material grains touch the heat-transfer area thoroughly. Within the axis direction, the temperature, moisture, mixture and grades of the materials is very small so as to guarantee the stability of whole process.
