Descriptions
Spray drying is the most widely used technology in liquid forming and drying industry. Spray drying technology is the best solution for the production of solid powder or particle products. Spray drying is one of the most desirable techniques when the finished product's particle size and residual moisture content, mass density and particle shape must meet precise standards.
Principle
When the high-speed centrifugal spray drying machine is running, the air is filtered and heated and enters the air separator at the top of the dryer. Hot air enters the drying chamber in a spiral pattern. The feed liquid is spun through a high-speed centrifugal ejector on the top of the tower, and is sprayed into tiny droplets of misty liquid. The material can be dried to form the final product through very short periods of contact with hot air. The final product will be discharged continuously from the bottom of the drying tower through the cyclone separator. The waste gas will be discharged by the blower.
Features
For the high speed centrifugal spray dryer, it consists of liquid delivery, air filtering and heating, liquid atomizing, drying chamber, air exhausting and material collecting, control system and so on, the features for each system as bellow:
● The liquid delivery system consists of liquid tank, magnetic filter, pump and so on as to ensure the liquid enters into the atomizer smoothly.
● Air filtering system and heating system
Before the fresh air enters into the heater, it should pass through the pre&post filter first, and then enters 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 enters into the drying chamber with high purity, the heated air should go through the high efficiency filter before entering the drying chamber.
● Atomizing system
The atomizing system consists of high speed centrifugal atomizer with inverter and so on.
The powder from the high speed centrifugal atomizer is between 40-120 microns.
● Drying chamber system
The drying chamber consists of the spiral shell, hot air distributor, main tower and relevant fittings.
Spiral shell and hot air distributor: The spiral shell and hot air distributor at the air inlet of the tower top can regulate air flow rotation angle according to the specific condition, guide the air flow inside the tower effectively and avoid the material stick on the wall.in the middle there is the position for installing the atomizer.
Drying tower: The inner wall is SUS mirror sheet, and welded by the arc welding. The insulation is rock wool.
The tower is manhole and view port as to convenient to clean and maintain the tower. For the tower body cross interface, pipe elbow are arc butt design, reduce dead angle; sealed type.
The main tower is equipped with air hammer, controlled by the pulse, and hitting the main drying tower timely as to avoid the dust stick on the wall.
● Air exhausting and product collecting system
For the material collecting system, there are several types such as cyclone, cyclone bag filter, bag filter, cyclone water scrubber and so on. The method is depending on the material property itself. For the filtering system for the outlet air, we have filter on request.
● Control system
HMI+PLC, each parameter can be displayed on the screen. Every parameter can be controlled and recorded easily.
