spray dryer

Spray dryer is a widely used process in powder forming and drying industries. It is suitable for producing powdery and granular products from liquid raw materials such as solutions, emulsions, suspensions, and pastes. Therefore, spray dryer is an ideal process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet precise criteria. Spray dryer is suitable for food, pharmaceutical, energy and chemical fields.

Centrifugal spray dryer is an air distributor on the top of the drying tower after fresh air is heated into clean hot air through the air inlet filter and heater, and the hot air enters the drying tower evenly in a spiral shape. The feed fluid is conveyed to the centrifugal spray or pressure nozzle at the top of the drying tower by the supply pump, and the rotating spray is formed into extremely fine atomized droplets, which are in contact with the hot air in the downstream, and the moisture evaporates rapidly, and is dried into finished products in an extremely short time. The finished product is discharged from the bottom of the drying tower and the cyclone separator, and the exhaust air is vented after being purified by the dedusting system.

Product Features: 1. Adopt rotary cutting air inlet technology and adjustable volute to ensure uniform distribution of materials and no reverse top. 2. The heat source can be electric heating, steam heating or a combination of various heating methods to ensure high efficiency and low consumption. 3. The whole machine is compact and beautiful in structure, easy to operate, the hot air chamber can be disassembled and cleaned, and the inlet air temperature can be adjusted and controlled. 4. Air jacket cooling system is adopted for the drying chamber and top parts to prevent the material from being melted and hung on the chamber 5. The inner wall of the drying chamber adopts an air rotary blowing device to eliminate or reduce the sticking phenomenon. 6. The powder collecting system adopts dehumidification air blowing cooling technology to cool the product and prevent moisture absorption and agglomeration. 7.It with GMP production requirements, dry air cleanliness is better than 100,000 grades, easy to clean, and product quality is stable.
