Spray drying is the technology most widely used in the liquid
technology s haping and in the drying industry.The drying
technology is most suitable for producing solid powder or particle
products from liquid materials,such as:solution, emulsion,
suspension and pumpable paste states,For this reason,when the
particle s ize and distribution of the nal products,residual water
contents, mass density and the particle shape must meet the precise
standard, spray drying is one of the most desired technologies.
After been ltered and heated the air enters into the air distrbutor
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 ne mist liquid
beads.Throug the very short time of contacting
the heat a ir,the materials can be dried into the nal products.The
nal products will be discharged continuously from the bottom of the
drying tower and from the cyclones. The waste gas will be
discharged from blower .
The drying speed is high when the material liquid is atomized,the
surface area of the material will increase greatly.In the hot-air
ow,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 nal products own the good uniformity, ow ability &
solubility. And the nal products are high in purity and good in
quality .The producition 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 managment.
