LPG-5 High-Speed Centrifugal Spray
Dryer
I. Principle:
After been filtered and heated the air enters into the air distributor on the
top of the dryer. The hot air enters into the drying room in the spiral form
and uniformly. Passing through the high-speed centrifugal sprayer on the
top of the tower, the material liquid will rotate and be sprayed into the
extremely fine mist liquid beads. Through the very short time of
contacting the heat air, the materials can be dried into the final products.
The final products will be discharged continuously from the bottom of the
drying tower and from the cyclones. The waste gas will be discharged
from blower.
II. Features:
The drying speed is high when the material liquid is atomized, the surface
area of the material will increase greatly. In the hot-air flow,95%-98% of
water can be evaporated at a moment. The time of completing the drying
is only several seconds. This is especially suitable for drying the heat
sensitive materials.
Its final products own the good uniformity, flow ability & solubility. And
the final products are high in purity and good in quality.

The production procedures are simple and the operation and control are
easy. The liquid with moisture contents of 40-60 %( for special materials,
the contents might be up to 90%).can be dried into the powder or particle
products once a time. After the drying process, there is no need for
smashing and sorting, so as to reduce the operation procedures in the
production and to enhance the product purity. The product particle
diameters, looseness and water contents can be adjusted through changing
the operation condition within a certain range. It is very convenient to
carry out control and management.
