high speed centrifugal spray dryer
Higao Tech manufacture high quality high speed centrifugal spray
dryer for liquid drying and granulation in china. Used to spray
liquid materials inside the drying chamber to make dry powder or
dry granules.
1. Introduction and Application:
High speed centrifugal spray dryer is widely applied in liquid
technique shaping and drying industry.
Suitable for producing powder, granules or blocked solid products
from emulsion, suspension, solution, paste liquid and so on.
When the distribution of granule size, final moisture content,
stacking density, and shape of granule of finished product must
conform to accurate standard, centrifugal spray dryer is an ideal
process.
Particularly for liquid spray and drying shows excellent advantages
in drying polymer and resin, dyestuff and pigment, ceramic, glass,
pesticide and fertilizer, carbohydrate, dairy products, detergent
and surfactant, organic and inorganic compound etc.
2. Working Principle:
After being filtrated and heated, the hot air enters the air
distributor uniformly on the top of the drying room. The hot air is
in spiral form.
Liquid material will be sprayed into extremely fine liquid beads
like fog through the spraying nozzle on top of the drying tower.
After contacting the heated air, in very short time, the moisture
vaporizes rapidly; the liquid material is fully dried into final
products.
The final products will be discharged continuously from the bottom
of the cyclone separator. And the waste gas will be discharged from
blower.
3. Features:
(1) Quick drying speed, the surface area of liquid material after
atomizing is increased greatly. In the flow of hot air, 95~98%
moisture in liquid material can be evaporated at the very moment.
The time of drying is only in several seconds. Especially fit for
drying heat sensitive materials.
(2) Final product has good uniformity, fluidity, flowability,
solubility, high purity, and good quality.
(3) Easy to control and operate.
(4) Liquid material with moisture of 0～60% (special material may
reach 90%) can be dried to powder or granule only once.
(5) No need to crush or separate the final products after drying.
So it reduces productive procedure and raises the purity of final
products.
(6) The particle size, stacking density and moisture content of
final product can be adjusted within certain scope through
exchanging operation condition.
