Principle
After been filtered and heated the air enters into the air distributor on the top of the dryer. The hot air enters into the drying room in the spiral form and uniformly. Passing through the high-speed centrifugal sprayer on the top of the tower, the material liquid will rotate and be sprayed into the extremely fine mist liquid beads. Trough the very short time of contacting the heat air, the materials can be dried into the final products. The final products will be discharged continuously from the bottom of the drying tower and from the cyclones. The waste gas will be discharged from blower.

Features of spray dryer
For the LPG series high speed centrifugal spray dryer, it consists of of liquid delivery, air filtering and heating, liquid atomizing, drying chamber, air exhausting and material collecting, control system and so on, the feature for each system as bellow:
ï¼‘.The liquid delivery system consists of liquid tank, magnetic filter, pump and so on as to ensure the liquid enter into the atomizer smoothly.
ï¼’.Air filtering system and heating system
Before the fresh air enter into the heater, it should pass through the Pre&post filter first, and then enter the heater for heating. For the heating method, there are electrical heater steam radiator, gas furnace and so on. Which method to choose depends on the customer site conditions.To ensure the drying medium enter into the drying chamber with high purity, the heated air should go through the High efficiency filter before enters the drying chamber.
3. Atomizing system
The atomizing system consists of high speed centrifugal atomizer with inverter and so on.
