概述
该产品可对膏状、颗粒状、粉状、浆状物料间接加热或冷却，可完成干燥、冷却、加热、灭菌、反应、低温燃盛等单元操作。设备中特殊的楔型搅挥传热浆叶，具有较高的传热效事和传热面自清洁功能。
  空心轴上密集排列着楔型中空浆叶，热介质从空心轴流向浆叶。单位有效容积内传热面积很大，热介质温度从-40°C到320°C.可以是水，也可以是其他液体.如热水、导热油等。间接传导加热没有携带空气带走热量，热量均用来加热物料。热量损失仅为通过器体保温层向环境的散热。楔型浆叶传热面具有清洁功能。物料颗粒与楔型面的相对运动产生洗刷作用，能够洗剧掉模型面上附着物料，使运转中一直保持着清洁的传热面。浆叶干燥机的克体为Ω型壳体内一般安排二到四根空心搅拌轴。壳体有密封端盖与上盖，为防止物料粉尘外泄而充分发挥作用。传热介质通过旋转接头，流经壳体夹套及空心搅拌轴，空心搅拌轴依据介质的类型而具有不同的内部结构，以保证的传热效果。

Applicable for drying or cooling of paste, particle, powder and slurry state of material, perform the process of drying, cooling, heating, sterilizing, reacting and combustion under low temperature. The special stirring and heating transferring blade, makes high heat transferring  eficiency, and provide self-cleaning function.The special chock shaped stirring and heat transferring blade has high heating efficiency and self-cleaning function of the heating transferring surface.
    Hollow chock shaped blades are concentrated on the hollow shaft. Heat media flow through the blade from the hollow shaft. The heat transferring area in the effective volume is very high. The temperature range of heating media is-40°C to 320°C. It might be steam, or liquid state, such as steam, thermal oil etc. Indirect heating, there's no heat carried out by air. All heat is utilized for to drying the material except the lost of heat insulation layers. The surface of chock shaped blade has self-cleaning function. The relative movements of the product particles and the chocked shaped surface might clean the material attached to the chock shaped surface, so to keep the cleanliness of heat transferring surface during working.The shell of hollow blade dryer is Ω. shape. 2 or 4 pieces of hollow stirring shaft are usually equipped in the shell. To avoid any leakage of material.there are sealed terminal cover and top cover with the shell. The heat transferring media flow through the rotation connector, jacket's shell and hollow stirring shaft. To ensure best transferring effect, the hollow string shaft adopts different interior structure in accordance with different heating media.

特点
1.浆叶干燥机能耗低:由于间接加热, 没有携带大量空气而带走热量，干燥器外壁又设置保温层，对浆状物料，蒸发1kg水仅需少量热量。
2.浆叶干燥机系统造价低:单位有效容积内拥有巨大的传热面.就缩短了处理时间。因设备尺寸变小，减少了建筑面积和建筑空间。
3.处理物料范围广: 使用不同热介质，既可处理热敏性物料,又可处理需高温处理的物料。常用介质有：水蒸汽、导热油、热水、冷却水等。既可连续操作也可间歇操作，可在很多领域应用。
4.环境污染小: 不使用携带空气，粉末物料夹带很少。物料溶剂蒸发量很小，便于处理。对有污染的物料或票回收溶剂的工况，可采用闭路循环。
5、操作费用低:该设备正常操作，仅1小时/天人。低速搅拌及合理的结构。磨损量小，维修费用很低。
6.操作稳定: 由于楔型浆叶特殊的压缩--膨胀搅拌作用，使物料颗粒充分与传热面接触，在轴向区间内，物料的温度、湿度、混合度梯度很小，从而保证了工艺的稳定性。

1. The heat consumption of blade is low: No heat carried out by the air because of indirect heating; there's no heat insulation layer with the exterior wall of the dryer. It consumes
to evaporate 1kg of water for to drying slurry state of material.
2. The cost of the blade dryer is low: The unit effective volume has very large heat transferring surface, so the processing time is shorted the size of the equipment becomes small. The building area and place are sharply decreased.
3. The range of material to be processed is wide: Heat sensitive material and the materials to be processed under high temperature might be processed with different heating media. The normal media are: steam, thermal oil, hot water and chill water. It might be continuous or batch operation, widely used in many areas.
4. The pollution is less: Without any carrying air, very few powder is carried out. The solvent evaporated is very few, it easy to be processed. For the material that might cause pollution or the solvent to be recovered, it might adopt sealed circulation.
5. The operation cost is low: 1 hour/day.operator is enough for normal operation. Low stirring speed and reasonable structure, the worn amount is few; and the maintenance fee is low.
6. Steady operation: The material particles fully contact heat transferring surface, because of the special compressing and swell-stirring effect of the chock shaped blade. The difference of the temperature, humidity and mixing effect are very small in the different axial area, so to ensure the stability of process.
