Spray drying is the technology most widely used in the liquid technology shaping and in the drying industry.The drying technology is most suitable for producing solid powder or particle products from liquid materials,such as: solution, emulsion, suspension and pumpable paste states,For this reason,when the particle size and distribution of the final products, residual water contents, mass density and the particle shape must meet the precise standard, spray drying is one of the most desired technologies. 

 1.The drying speed is high when the material liquid is atomized,the surface area of the material will increase greatly.In the hot-air flow,95%-98% of water can be evaporated at a moment.The time of completing the drying is only several seconds. This is especially suitable for drying the heat sensitive materials.
2. Its final products own the good uniformity, flow ability & solubility. And the final products are high in purity and good in quality. 

3.The producition procedures are simple and the operation and control are easy.The liquid with moisture contents of 40-60%(for special materials,the contents might be up to 90%).can be dried into the powder or particle products once a time. After the drying process, there is no need for smashing and sorting,so as to reduce the operation procedures in the production and to enhance the product purity.The product particle diameters,looseness and water contents can be adjusted through changing the operation condition within a certain range. It is very convenient to carry out control and managment.
