DESCRIPTION
The spray drying technology is the widest used 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, the spray drying is one of the most desired technologies
when the particle size and distribution of the final products,
their residual water contents, and the stocking density and the
particle shape can meet the precision standards.
WORKING PRINCIPLE
The air enters into the air distributor which on the top of the
drier after filtering and heating. The hot air in spiral form
equably enters into the drying room. When liquid raw material is
passing through the high-speed centrifugal sprayer on the top of
the tower, it will be rotated and sprayed into the extremely fine
mist liquid beads. Raw material can be dried to the final products
instantly while it contact with the heated air. The finished
products are discharged continuously from bottom of the drying
tower and cyclones segregator. The waste gas is discharged from
blower.
FEATURES
1. The drying speed is rapid. When liquid raw material is atomized,
the surface of the material will be enlarged greatly. 95% -98% of
water can be evaporated instantly in the hot airflow and the drying
is only a few seconds. This dryer is especially suitable to dry the
heat sensitive material.
2. The uniformity, flow capability & solubility of the dryer are
very good. The finished products have high quality and
high-purity.
3. Simple and stable operation, convenient control and debugging,
easy to achieve automatic operation.
4. The production process is simple, The dryer can dry the liquid
material which contains 40%-60%(90% for special materials) of
moisture into powder at once. There’s no need for smashing or
sieving after drying so the operational environment is clean and in
healthful condition, it also can avoid powder flying in the air
during drying process.
