Easy Control LPG Series High Speed Centrifugal Spray Drying Machine
Descriptions
Atomizing drying machine is the high efficient drying equipment, to make dry powder or granule from liquid, emulsion, suspension and pumpable pasty liquid, especially for thermosensitive material, it can keep color, original flavor and chemical feature of raw material, and the finished dry powder or granule have good quality,purity, fluidity and solubleness.
This equipment features by high accuracy & speed & efficiency, simple production process, labor-cost saving, widely applied in the industry of chemical, food, pharmacy, biochemistry, light industry,etc.
Principle
After filtering and heating, the air would enter into upper air-deployer
of drying tower, and then come in in hot spiral form. At the same
time, the raw liquid material would be atomized by tower from upper
inside, become the super tiny globule in mist type, the surface of
which would contact the hot air fully, then finished dry powder
would be achieved in short time and collected at the bottom of
tower and be discharged from cyclone separator, the gas would be
exhausted outside.
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.
Some Operation Issues:
1. Atomizating: Atomizing system must insure uniform spraying
fogdrops.
2. Hot airflow and fogdrops contacting: While the hot air come into
drying tower, user have to consider the air flowing way and angle.
No matter co-current flow, adverse current or mixed flow, user must
insure the sufficient heat exchange, which is the key way to make
sure the dry efficiency.
3. The angle design of pipelines and cone: It is pretty important
to choose the suitable angle, please contact us for more working
experience.
