Description of spray drying equipment:
Spray drying is the most widely used in liquid process shaping and
drying industry. Applies to most from solution, emulsion,
suspending liquid and paste liquid raw materials generated in the
powder, granular solid products. Therefore, when the particle size
distribution of the finished product, residual moisture content,
bulk density and particle shape must meet the precision standard,
the spray drying is an ideal process.
Principle of spray drying equipment:
Dry series Dryer series: After filtering and heating, air into the dryer on top of the air
distributor, hot air spiraling evenly into the drying chamber.
Material liquid via high-speed centrifugal atomizer, on top of the
tower body (rotating) into a very fine mist spray liquid bead,
contact with the hot air and flow, in a very short period of time
can be dry for the finished product. Finished products continuously
by drying the bottom and the output of the cyclone separator,
exhaust fan emptying.
Features of spray drying equipment:
· Fast drying speed, material liquid after atomization,
significantly increased surface area, in the hot air flow,
instantaneous evaporation can be 95% 98% moisture, to complete the
drying time only a few seconds, and especially suitable for drying
of thermal sensitive material.
· Products with good uniformity, fluidity and solubility, the
product high purity, good quality.
· Production process is simple, convenient operation and control.
Special material for 40-60% moisture content (90%) of the liquid to
a dry powder products, dried without crushing and screening, reduce
the production process, improve product purity. To the product
particle size, bulk density, moisture, within a certain range can
be adjusted by changing the operating conditions, control and
management is very convenient.
