Manufacturer Supply Automatic Industrial 150kg/H Spray Drying Tower
Lpg-150 spray drying tower
Spray drying equipment is widely used in liquid forming and drying industry.Suitable for producing powder and granular solid products from solution, emulsion, suspension and paste liquid raw materials.Therefore, when the shape of finished product must form a fixed standard, spray drying equipment can easily complete these works.
After fresh air is filtered and heated, it enters into the air distributor which on the top of the drier. The hot air in spiral form equably enters into the drying room.When liquid raw material are passed through the high-speed centrifugal sprayer on the top of the tower, it will be rotated and sprayed into the extreme slim mist liquid beads.
Raw material can be dried to the final products instantly while it contact with the heatedair.Finished products are discharged continuously from bottom of the drying tower and cyclones segregator. Wasted air is discharged from blower.
Features
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:
1.The liquid delivery system consists of liquid tank, magnetic filter, pump and so on as to ensure the liquid enter into the atomizer smoothly.
2.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.
The powder from the high speed centrifugal atomizer is between 40-120 microns.
4. Drying Chamber system
The drying chamber consists of the spiral shell, hot air distributor, main tower and relevant fittings.
The 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, ad 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
5. 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.
6. Control system
HMI+PLC, each parameter can be displayed on the screen. Every parameter can be controlled and recorded easily.
Centrifugal spray atomizer Features
1. High speed drying. The surface area of Raw Material liquid increased a lot after atomization through nebulizer, 95%-98% of moisture will be evaporated in high temperature airflow in a flash, only needs seconds time.
