XSG-18 Rotary Flash Dryer
I. General Application of XSG Flash Dryer
Rotary flash dryer is a new high efficient fluidized drying
equipment that we designed for solve the static drying’s low
efficiency and high consumption problem. When designing the
equipment, we combined the features of air stream drying and
fluidized drying together. So the machine has reasonable structure
and good performance, it really achieves the aim of low consumption
and high efficiency of fluidizing drying.
This machine has a wide application scope, it can be used for
drying in fire retardant, molecular sieve, rubber and plastic
assistance, pesticide, pigment, dyestuff, fine chemicals,
feedstuff, pharmaceutical and part intermediate industries.
Hot air enters into stirring, crushing and drying chamber in a
certain speed from the air inlet that at the bottom of dryer and
producers vigorous eddy airflow. Material is acted by centrifugal
force, shearing force, impacting and friction, the particle size of
material becomes very small and mass and heat transmission is
strengthened. At the bottom of dryer, big damp granules is crushed,
small and low moisture content granules rise with the rotation air
stream. During the rising process, the granules are dried further.
Because of the rotary flow of air and solid, inertia of solid phase
is higher than gaseous phase, the relative speed of air and solid
is big, it strengthens mass and heat transmission, so drying
intensity is high.
II. Features of XSG Flash Dryer
1. Several feeding device can be chose, feeding is continuous and
stable, no phenomenon of bridging.
There is special cooling device at the bottom of dryer, it can
avoid the material that in the bottom high temperature area be bad.
There is special air sealing device and cooling device for bearing,
it can make the life of transmission part longer effectively.
There is special air distributing device, it can reduce the
resistance of equipment, and make the air speed in drying tower
There is classify ring and turbojet plate, the fineness and final
moisture of product can adjusted and controlled.
Circumference air speed in the drying tower is high, the residence
time of material is short, it can avoid the material stick on the
wall and thermal sensitive materials so bad.
III. Application scope
Organics: Atrazine (pesticides),lauric acid cadmium benzoic acid,
sodium oxalate, sterilization Dan, cellulose acetate, organic
Dyestuff : Anthraquinones, black iron oxide, indigo dye, butyrate,
titanium oxide, zinc sulfide, various azo dye intermediates
Inorganic substance: Borax, calcium carbonate, hydrogen peroxide,
copper sulfate, ferric oxide, TanSuanBei, three antimony oxide, all
kinds of metal salt,synthetic cryolite etc.
Food: Soybean protein, gelatinized starch, vinasse, triticum, wheat
