High Speed Centrifugal Spray Dryer
Stainless Steel Centrifugal Spray Dryer for Yeast Egg Yolk Copper
Chloride
Introduction
Description
The spray drying is the technology which is widely used in the
liquid technology shaping and in the drying industry. The drying
technology is most suitable for producing the powder or particle
solid products from the materials, such as: Solution, emulsion. So
when the particle size and distribution of the final products,
their residual water contents, the stacking density and the
particle shape must meet the precision standard, the spray drying
is one of the most perfect technologies.
Principle
After the filtering and heating, the air enters into the air
distributor from the top of the drier. The hot air enters into the
drying room in the spiral form and uniformly. By passing through
the high-speed centrifugal spray on the top of the tower, the
material liquid will rotate and be sprayed into the extremely fine
mist liquid beads. Through the very short time of contacting the
heat air, the materials can be dried into the final products. The
final products will be discharged continuously from the bottom of
the drying tower and from the whirling separator. Finally the waste
gas will be discharged from blower.
Features
A. Fast drying speed. Liquid materials after atomization will
increase its surface area largely and can be evaporated its
moisture 65% to 98% instantly in the hot air flow so as to finish
drying within 5 to 15 seconds.It is specially suitable for drying
of heat sensitive materials.
B.Dried products have even granule, good flow ability and
solubility, high purity and good quality.
C.Simple and stable operation,easy adjustment and control as well
as automation.
D.Simplifying process of production,superior and sanitary operation
environment,and flying dust can be avoided during the drying
process.
