1. General description of Centrifugal Spray Dryer
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.
The working of the pressure Spray Dryer as follows: the liquid of raw material is pumped in through diaphragm pump. The liquid of raw material be atomized into tiny droplets. Then it gathers with hot air and falls off. Most parts of powder material will be collected from the outlet of the main tower's bottom. For the fine powder, we will still continuously collect them by the cyclone separator and cloth bag filter or water scupper. But it should depend on the material property.

2. Features of Centrifugal spray dryer
1.High collecting rate;
2.No stick onto the wall;
3. Fast drying;
4. Energy saving;
5. High efficiency;
6. Especially applicable for heatsensitive material;
7. For the heating system for the machine, it is very flexible. We can configure it based on the customers' specific conditions such as steam,electricity, gas furnace and so on, all of them we can design it to match our spray dryer;
8. Control system has more choices, such as push button, HMI&PLC and So on.
