Overview of small experimental spray dryer:

　　Spray dryer is a kind of continuous atmospheric pressure dryer. Spray the liquid material into a mist using special equipment, allowing it to come into contact with hot air and be dried. Used for drying some heat sensitive liquids, suspensions, and viscous liquids, such as milk, eggs, tannins, and drugs. It is also used for drying fuels, intermediates, soap powder, and inorganic salts.

Working principle of small experimental spray dryer:

　　The air is filtered and heated, entering the top air distributor of the dryer, and the hot air enters the drying chamber in a spiral and uniform manner. The feed liquid passes through the high-speed centrifugal atomizer on the top of the tower body, and (rotating) spray into extremely fine mist like liquid beads, which can be dried into finished products in a very short time in parallel with hot air. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the induced draft fan.

Features of small experimental spray dryer:

　　The drying speed is fast, and the surface area of the material liquid greatly increases after atomization. In the hot air flow, 95% -98% of the water can be instantly evaporated, and the drying time is only a few seconds. It is particularly suitable for drying heat-sensitive materials.

　　The product has good uniformity, fluidity, and solubility, high purity, and good quality. Simplify the production process and facilitate operation and control. For liquids with a moisture content of 40-60% (up to 90% for special materials), they can be dried into powder products in one go, without the need for crushing and screening after drying, reducing production processes and improving product purity. The particle size, bulk density, and moisture of the product can be adjusted within a certain range by changing the operating conditions, making it easy to control and manage.

Main purposes of small experimental spray dryer:

　　It is mainly suitable for spray drying of suspended liquid, high viscosity material or solid content liquid.
