Description: The spray dryer is the widest used technology in the liquid shaping technology and in the drying industry. It is the most suitable for producing powder, particle or block solid products from materials of solution, emulsion, soliquoid and pumpable paste states. Therefore, when the particle size and distribution of the final products, theirresidual water contents, the stocking density and the particle shape meet the precision standards, the spray drying is one of the most desired technologies.


Principle: After filtering and heating, the air enters into the air distributor at the top of the dryer. The hot air enters into the frying chamber in the spiral form uniformly. By passing through the high-speed centrifugal atomizer at the top of the tower, the material liquid will be rotated and sprayed into extremely fine mist liquid besds. Through the short time of contacting with hot air, the materials can be dried into the finished products. The finished products will be discharged continuously from the bottom of the drying tower and from the cyclone separator. The waste gas will be discharged by blower.


At a high speed of drying, after the spraying of the material liquid, the surface area of the material will be increased greatly. The time of completing the drying needs only several seconds.

This is especially suitable for drying the heat sensitive materials. Its final products own the good uniformity, mobility, dissolving capacity. And the final products are high in their purity and good in their quality. The production procedures are simple and the operation and control are easy. After the drying, there is no need for smashing and sorting, so as to reduce the operation procedures in the production and to enhance the product purity. The product particle diameters, looseness and water contents can be adjusted through changing the operation condition in a certain scope. It is very convenient to carry out the control and management.
