Product description of Spray Dryer
The spray machine for drying is the technology most widely used in the liquid technology shaping and in the drying industry.
The drying technology is the most suitable for producing solid powder or particle products from liquid materials, such as: solvent, emulsion, suspension and pumpable paste states, fro 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 technology.

Working Principle of Spray Dryer
The spray dryer is to disperse the material to be dried into particles, contact with hot air, and quickly remove most of the water by increasing the area of water evaporation to accelerate drying, and finally obtain the dried product.
Main Features of Spray Dryer
1.Rapid drying speed, which just takes 5-15 seconds.
2. It is especially suitable for drying the heat sensitive materials. Its final products own the good uniformity, mobility, dissolving capacity. And the final products are high in purity and good in quality.
3.Simple processing and easy operation, which is suitable for continuous production.
4.The product has a good degree of uniformity, liquidity and dissolubility with high quality and purity.
5.Can adjust the product diameter, density and water content in some degree which is convenient to control and manage.
