1. It can be used to indirectly heat or cool paste, granular, powder, and paste materials.
2. A series of operations such as drying, cooling, heating, sterilization, reaction, and low-temperature combustion can be completed.
3.The special wedge-shaped stirring heat transfer blade in the equipment has higher heat transfer efficiency and self-cleaning function of the heat transfer surface.
4. The wedge-shaped blade heat transfer surface has a self-cleaning function. The relative movement of the material particles and the wedge-shaped surface produces a scrubbing effect, which can wash off the attached material on the wedge-shaped surface, so that a clean heat transfer surface is maintained during operation. The shell of the blade dryer is Ω type, and two to four hollow stirring shafts are generally arranged in the shell. The shell has a sealed end cover and an upper cover to prevent material dust from leaking out and give full play to its effect.
Hollow shaft dense arrangement with the wedge-shaped hollow blade, the heat medium through the hollow
shaft flow through the blade. The effective volume of heat transfer area is very large, the heat medium temperature(-40℃~320℃) can be water vapor, also can be hot water or heat conducting oil.
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 pulp and jacket access to hot oil, heating at the same time, the upper part of the is harge port at the same time through the heated dry air after further drying, thus greatly increasing the drying strength of the device. Evaporated moisture from the tail gas out of the dryer, wet air discharged by the induced draft fan outdoors.
1. Hollow blade 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 blade 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. A wide variety of process problems can be solved by using any kinds of heating source. It is especially suitable for drying heat sensitive materials and light temperature 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 the 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 the 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 the whole process.
