Overview:
Spray drying is a widely used process in the liquid forming and drying industry. It is suitable for producing powdered or granular solid products from solutions, suspensions, and pasty liquid raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density, and particle shape of the finished product must meet precise standards, spray drying is an ideal process.
Principle:
The air is filtered and heated, then enters the air distribution unit at the top of the dryer, where the hot air spirals evenly into the drying chamber. The liquid material is sprayed into fine mist droplets by a high-speed centrifugal atomizer at the top of the tower (rotating), coming into contact with the hot air in parallel. The product can be dried into finished goods in a shorter time. The finished goods are continuously discharged from the bottom of the drying tower and the cyclone separator, while the waste gas is exhausted by the fan.
Features:
● Fast drying speed; after atomization, the surface area of the material-liquid is greatly increased, which can evaporate instantly in the hot air flow.95%-98%Moisture content, with a complete drying time in just a few seconds, ideal for drying heat-sensitive materials.
The product boasts excellent uniformity, fluidity, and solubility, with a high purity and good quality.
● Simplified production process, easy operation and control. For moisture content40-60%(Special materials available90%)Our liquid can be dried into a powdered product in one step, eliminating the need for crushing and sieving, thus reducing production processes and enhancing product purity. The particle size, bulk density, and moisture content can be adjusted within a certain range by modifying operating conditions, making control and management quite convenient.

◆ Airflow Drying, also known as flash drying, has been applied in China's chemical industry since the 1960s. Our factory has been utilizing advanced technology both domestically and internationally since its establishment to provide high-quality and cost-effective equipment for industries such as chemicals.
