一、工作原理与应用范围介绍 Introduction of Working Principle and Scope of Application
溶液或悬浮液、浆料等经过高压泵将料液压至2-20MPa送入雾化器将料液喷成雾状，然后与顺（逆）流的热空气充分进行热交换从而达到快速干燥之目的，广泛适用于大批量（小时产量可达几十吨）的物料快速瞬间脱水干燥。
Solution or suspension, sizing agent, etc. are pressurized by the high pressure pump at 2-20MPa and sent into the atomizer, which spays the feed liquid into vapor. Then, the vapor will fully conduct heat exchange with the downstream (upstream) hot air, achieving the purpose of rapid drying. It is widely applied in rapid and constant dehydration and drying of large batches of materials (scores of tons in a hour).
二、特点Characteristics
1.压力喷干出来的产品相对离心喷干出来的产品粒径粗、产品的堆密度大。
2.小时产量大，采用多喷头可实现小时产量十几吨甚至几十吨。
3.干燥速度快，料液经雾化后表面积大大增加，在热风气流中瞬间就可蒸发95%-98%的水份，完成干燥的时间仅需十几秒到数十秒，特别适用于热敏性物料的干燥。
4.所得产品为球状颗粒，粒度均匀，流动性好，溶解性好，产品纯度高，质量好。
5.使用范围广，根据物料的特性，可以用热风干燥，也可以用冷风造粒，对物料的适应性强。
6.操作简单稳定，控制方便，容易实现自动化作业。
1. The particle size and bulk density of products spray-dried under pressure are larger than those spray-dried in a centrifugal way.
2. The application of multiple nozzles can realize the hourly output of over ten and even scores of tons.
3. The drying speed is fast. After atomization, the superficial area of feed liquid will be increased largely. 95%-98% of moisture can be evaporated instantly in the hot air flow. The time for completing drying takes only over ten to scores of seconds. It is particularly applicable to the drying of heat sensitive materials.
4. The products are epigranular spherical particles with good mobility, solubleness and quality and high purity.
5. It has a large scope of application. Depending on the characteristics of materials, it can be used for hot air drying and cold air pelleting and is strongly adaptable to materials.
6. The operation is simple, stable and easy to control, and automated operation can be achieved easily.
