full 304SS consutruction Tungsten Carbide Centrifugal Spray Dryer
Application
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.
working princple
After been filtered and heated the air enters into the air
distrbutor on the top of the dryer.The hot air enters into the
drying room in the spiral form and uniformly. Passing through the
high-speed centrifugal sprayer on the top of the tower,the material
liquid will rotate and be sprayed into the extremely fine mist
liquid beads.Throug the very short time of contacting the heat
air,the materials can be dried into the final products.The final
products will be discharged continuously from the bottom of the
drying tower and from the cyclones. The waste gas will be
discharged from blower.
Description
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.
Its final products own the good uniformity, flow ability &
solubility. And the final products are high in purity and good in
quality.
