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.
2. Adopts Single position spray drying to make the liquid drop and
hot air running in same position. Although the temperature of the air is high, the hot air contacts Liquid Drop once come into
drying tank. So the temperature decreased at once to protect the
material out of over heated. This is machine is also fit for the
materials which are sensitive with Heating.
3. Because the drying is processed in a flash, so the finished
product is Ball Shape with good mobility and good solubility.
4.The machine is Simple production with easy operation control
system used for drying 50-80% moisture contained materials, even
some special material with 90% moisture contained can be dried in a
flash to powder. Most of the materials no need to be pulverized or
sieved again after dried
