Paste XSG Flash Drying Machine (Spin Flash dryers ) (Rotating flash Dryer)( Flash cooler )

I. General Application of XSG Flash Dryer

Rotary flash dryer is a new high efficient 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 because balance.

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 pigments, etc
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 starch.

Feed system

The feed system consists of a feed vat where a discontinuous flow of product is buffered and fragmented by an agitator prior to continuous drying. A variable speed feed screw (or pump in the case of fluid feed) forwards the product to the drying chamber.

Drying chamber

The rotor at the conical base of the drying chamber fluidizes product particles in a drying-efficient hot air flow pattern in which any wet lumps are rapidly disintegrated. Hot air is supplied by a temperature-controlled air heater and speed-controlled fan, entering the drying chamber at a tangent in order to establish a turbulent, whirling air flow.

Airborne, fine particles pass through a classifier at the top of the drying chamber, while larger particles remain in the air flow for further drying and powdering.

The drying chamber is rigidly designed to withstand pressure shock in the event of explosive combustion of flammable particles. All bearings are effectively protected against dust and heat.

Bag filter

Powder from the drying chamber is collected in bag filter, while the outlet airleaves the system at the top via a suction fan.

Pneumatic coolers are a simple and reliable method of cooling and conveying dried product. In many instances ambient air will achieve the desired cooling duty. Where required, greater cooling capacity and a finer degree of control can be achieved with conditioned air at a controlled humidity and temperature.

Feature :

1. This machine combines the whirl technology with the fluidity, ejection and smashing step technologies.

2. The equipment is compact and small in size, high in production efficiency and continuous in the production. It has realized that " small equipment can perform the large production".

3. The drying capacity for this machine is big but its energy consumption is low. Its heat efficiency is high.

4. The material stay time is very short. The quality of the final products is very good. The machine can be used for drying the heat sensitive materials.

5. For the negative pressure or the micro-negative pressure operation, the machine is good for its tightness and high in the efficiency so as to eliminate the environmental pollution.

6. High drying efficiency providing low energy costs

7. Continuous processing with short processing time

8. Low operator overheads and minimum maintenance costs

9. Controlled residence time enabling high temperature drying

10. Available in cGMP compliant configurations
