LPG Series High Speed Centrifugal Atomizing Dryer
The spray drying is the widest used technology in the liquid shaping technology and
in the drying industry. It is most suitable for producing powder, particle, or block solid
products from materials of solution, emulsion, soliquoid and pumpable paste states.
Therefore, when the particle size and distribution of the fi nal products, their residual
water contents, the stocking density and the particle shape meet the precision
standards, the spray drying is one of the most desired technologies

Principle of work:
After fi ltering and heating, the air enters into the air distributor at the top of the dryer,
The hot air enters into the drying chamber in the spiral form uniformly. By passing
through the high-speed centrifugal atomizer at the top of the tower, the material
liquid will be rotated and sprayed into extremely fi ne mist liquid beads. Through the
very short time of contacting with hot air, the materials can be dried into the fi nished
products. The fi nished products will be discharged continuously from the bottom of
the drying tower and from the cyclone separator. The waste gas will be discharged
● High speed of drying. After the spraying of he material liquid, the surface area
of the material will be increased greatly. In the hot-air fl ow, 95%-98% of water can
be evaporated at a moment. The time of completing the drying needs only several
● It is especially suitable for drying the heat sensitive materials. It's fi nal products
own the good uniformity, mobility, dissolving capacity. And the final products are
high in purity and good in quality.
● The production procedure is simple and the operational control is easy. The liquid
with the moisture contents 40-60%(for special materials, the contents may reach
90%) can be dried into power or particle products once a time. After the drying, there
is no need for smashing of sorting, so as to reduce the operation procedures in the
production and enchance the purity. The product particle diamenters, looseness and
water contents can be adjusted through changing the operation condition in a certain
scope. It is very convenient to carry out the control and manag
