Product Description
1. Drying liquid or slurry materials into dry powder 2. Atomizing type: centrifugal atomizer 3. Evaporation capacity: 5-100 kg/h 4. Heat source: steam, electricity, thermal oil or gas/oil/coal fired hot air generator
1) Particle size control: The dry particle size can be easily controlled by atomization of the liquid feed and the design of the hot gas inlet. This spray dryer can typically produce between 30 to 500 micron average particle size, in a bell shaped distribution.
2) The evaporative cooling of product: The heat and mass transfer during drying occurs in the air and vapor films surrounding the droplet. This protective envelope of vapor keeps the particle at the saturation temperature. As long as the particle does not become "bone-dry", evaporation is still taking place and the temperature of the solids will not approach the dryer outlet temperature.
3) Short residence time: The surface area produced by atomization of the liquid feed enables a short gas residence time, ranging from 3-10 seconds depending upon the application, which permits spray drying without thermal degradation.
4) Flow properties of dry product: The shape of most spray dried particles is spherical, which provides for fluid-like flow properties. This makes many downstream operations, such as packaging, pressing, filtering, and handling easier and less costly.
5) Size design of drying chamber: The size of drying chamber is specially designed to prevent droplets sticking to the inner wall, dried powder accumulating on the cone part and guarantee enough residence time.
Q: What information should be provided in order to get a proposal or quotation?
A: All our spray dryers are customerized. Before we can work out a detailed quotation, we have to know the following information:
1) What liquid material are you going to dry? Moisture type and viscosity?
2) Moisture content before drying? Target moisture content of dried powder?
3) Required powder size distribution?
4) Your recommended drying temperature?
5) Heat souce? Steam, electricity or hot air generator
6) Construction material ? SS304/SS316L
Q: How the dryer will be delivered?
A: Drying chamber is fixed in a steel frame and then loaded into container. Spray drying chamber of more than 25 kg evaporation capacity can't be shipped by normal container.
Q: Do you provide free drying test?
A: Yes. We have pilot plant for free drying test.
