Spray drying is a process widely used in liquid process forming and drying industry, which is suitable for generating powder and granular solid products from solutions, lotion, suspensions and pumpable paste liquid raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet the actual standards, spray drying is an ideal process.
Working principle
After being filtered and heated, the air enters the air distributor at the top of the dryer, and the hot air enters the drying chamber in a spiral shape evenly. The feed liquid passes through the high-speed centrifugal atomizer at the top of the tower body, and the (rotating) spray becomes a very fine mist like liquid bead, which flows in parallel with the hot air, and is dried into a finished product in a very short time. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the waste gas is discharged by the fan.
