Spray dryer is a device that can complete drying and granulation at the same time. According to the requirements of the process, the pressure, flow rate, and nozzle size of the material liquid pump can be adjusted to obtain the required spherical particles in a certain size ratio. Spray dryer is a type of continuous atmospheric dryer. The liquid material is sprayed into a mist form by special equipment, and it is dried by contact with hot air. Used to dry some heat-sensitive liquids, suspensions and viscous liquids. It is also used to dry fuels, intermediates, soap powder and inorganic salts.
 
Lab spray dryer after filtering and heating, the air enters the air distributor at the top of the dryer, and the hot air enters the drying chamber uniformly in a spiral shape. The material liquid is sprayed (rotated) into a very fine mist-like liquid bead through a high-speed centrifugal atomizer on the top of the tower body, and can be dried into a finished product in a very short time in contact with hot air in parallel. The finished product is continuously output from the bottom of the drying tower and the cyclone, and the exhaust gas is evacuated by the induced fan.
 
Performance characteristics
The drying speed is fast, and the surface area of ​​the material liquid is greatly increased after being atomized. In the hot air current, 95% -98% of water can be evaporated in an instant, and the drying time is only a few seconds. It is especially suitable for drying heat-sensitive materials.
The product has good uniformity, fluidity and solubility, high purity and good quality.
The production process is simplified and the operation and control are convenient. For liquids with a moisture content of 40-60% (special materials can reach 90%) can be dried into powder products at one time, the control and management are very convenient.
