Specifications

The drying speed is high when the material liquid is atomized,the surface area of the material will increase greatly.

Product introduction
Spray drying is the technology most widely used in the liquid technology s haping 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 s ize and distribution of the nal 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 Principle
After been ltered 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 ne mist liquid beads.Throug the very short time of contacting
the heat a ir,the materials can be dried into the nal products.The nal products will be discharged continuously from the bottom of the drying tower and from the cyclones. The waste gas will be discharged from blower .

Characteristics
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 ow,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 nal products own the good uniformity, ow ability & solubility. And the nal products are high in purity and good in quality .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.
3.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.
