4、桨叶具有自洁能力。桨叶相向旋转，叶片的两个斜面反复搅拌、压缩、松弛并推进物料，使页面具有独特的自洁能力，加热面不断获得更新，也使桨叶干燥机的传热系数高于其他任何传导干燥方式。

The sale of second-hand Tatsu hollow blade drier sludge dryer paddle dryer manufacturers offer a hollow blade dryer is a heat conduction based horizontal stirring type dryer. Because the stirring blade inside the hollow shape on the oars, solid called hollow blade dryer. Paddle dryer abroad has been developed for many years, this model has been developed in foreign countries and four axes of two kinds of structures, a number of specifications of the series of products. Paddle dryer was first developed by the German success, after the introduction of the technology in Japan, and to improve the development of the two axes and four axes, more than and 10 kinds of structures, the series of products. The dry heat required by the heat conduction of indirect heating, so the drying process takes only a small amount of gas to remove moisture, which greatly reduces the heat loss by gas away, improves the utilization rate of heat and intensity of dry hollow blade drying machine is a kind of energy-saving drying equipment. It is suitable for granular and powder materials of the dry, the paste can also be smooth.

Paddle type dryer is a kind of horizontal stirring type dryer. The main structure is a hollow shell with W type jacket with a pair of low speed rotary hollow shaft, the shaft is welded with a plurality of mixing blades, jacket and a hollow stirring blade, which are connected to the heat carrier, two kinds of heating surface of material heating. The heat carrier is usually fed from the middle part of the dryer, and the heat carrier is discharged from the other side through a material layer which is in a state of agitation.
The hollow shaft is densely arranged with a wedge shaped hollow blade, and the heat medium flows through the blade through the hollow shaft. The effective heat transfer area of the unit effective volume is very large, the heat medium temperature from -40~320 degrees C, can be water vapor, also can be liquid type: such as hot water, heat conduction oil, etc.. Indirect conduction heating, without carrying air away heat, heat is used to heat the material, heat loss is only through the thermal insulation layer to the environment of heat. The heat transfer surface of the wedge blade has the function of self cleaning, and the relative motion of the material particles and the wedge surface can be washed, and the adhesive material on the wedge surface can be washed away.
1, material retention time can be adjusted, can deal with high water content material, also can obtain very low water content material;
2, typical conductive drying mode, energy saving, high conductivity, high thermal efficiency;
3, due to the required heat all by the hollow blades and jacket supply, to reduce the exhaust gas humidity, a small amount of hot air can be added, dust entrainment low, tail gas is easy to handle, do not need dust and other auxiliary equipment.
4, the blade has the ability of self cleaning. The blades rotate in the opposite direction, two inclined blade stirring, compression, relaxation and promote material, make the page has a unique self-cleaning ability, the heating surface continuously updated, the heat transfer coefficient of blade dryer is higher than any other conduction drying methods.
