Spray Dryer is the widest used in the liquid forming process and in drying industry. The drying technology is most suitable for powder, particle products from materials, such as, solution, emulsion, SC and pumpable paste states material.
For this reason, when the particle size and distribution of the final product, their residual water contents, the stacking density and particle shape must meet the precision standard, spray drying process is one of the most desired processes.
After filtering and heating, the air enters into air distributor on top of the Spray Dryer.
The hot air enters into the drying room in spiral form and uniformly.
By passing through high-speed centrifugal atomizer on top of tower, the material liquid will rotate and be sprayed into the extremely fine mist liquid beads. Through the very short time of contacting with heating air, the material can be dried into final products.
The final products will be discharged continuously from the bottom of drying tower and from cyclone separator. The waste gas will be discharged from exhaust fan.
At a high speed of drying, after spraying of the material liquid, the surface area will be increased greatly. In the hot air flow, 95%-98% of water can be evaporated at a moment. The time of completing the drying needs only several seconds.
This is especially suitable for drying the heat sensitive materials. Its final products own good uniformity,mobility, dissolving capacity. And the final products are high in their purity and good in their quality.
