What are the characteristics of the freeze spray dryer?

　　As we all know, spray dryer is to atomization of materials, increase the surface area to volume ratio, and then dry through the full contact with hot air. Then what is the freezing spray dryer? What are the characteristics.

　　1. Organic combination of spray drying and freeze-drying.

　　The working principle of the freeze dryer is to condense the material containing water into a solid state, then remove the solid water by sublimation process, and finally get the dried product. The freezing spray dryer combines the two together, effectively utilizing their advantages, greatly reducing the drying time of the material and improving the work efficiency.

　　2、 It can be preserved for a long time

　　After the material is dried into powder by spray dryer, the material is easy to be preserved after freezing, and it is not easy to be affected by the change of environmental conditions. And the freezing process does not change the biochemical properties of the product, so when it needs to be used, water can be added to remove the frozen state and continue to put into use.

　　3、 Easy to operate, excellent performance

　　The freezing spray dryer includes most of the two advantages of the freeze dryer and spray dryer, and has made some improvements on the basis of it. The refrigeration system used in this system is a fully enclosed compression refrigeration system, which has high refrigeration speed and high drying and freezing efficiency.

　　4、 The product has high solubility

　　The dry products obtained by the freeze spray dryer have higher solubility, and also guarantee the effective characteristics of the products without changing their biochemical characteristics. So now most of the market use this method for milk powder production and processing and drug microencapsulation technology.

　　5、 Effectively ensure the biochemical characteristics of the product

　　In the process of atomization drying, the material is dried by contacting with hot air, evaporating water and leaving solid products. However, it is easy to damage the structure and physical and chemical properties of the product at high temperature, which makes the product easy to fail. So the combination of freeze drier and spray dryer perfectly solves this problem. It quickly freezes the product after atomization drying, which greatly reduces the change of its nature, so it is more and more popular with major enterprises.

　　The freezing spray dryer is a major breakthrough in drying technology, and has made a good development prospect for the development of drying technology. It can be widely used, loved by many businesses, and its good performance is closely related.
