ISO9001 LPG Series High Speed Centrifugal Spray Dryer

PRODUCT DESCRIPTION
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.
