China XSG Series Spin Flash Dryer - Efficient Drying Solution from Leading Suppliers and Factory
Principle
Materials enters into the dryer through the screwing feeding ostium, under the powerful high speed effect of stirring, materials are distributed by the function of striking, friction, shearing and cutting, raw materials are instantly smashed and fully contact with hot air, they are heated and dried, the dried powder material will be raised with the hot-air flow, small particles are discharged from the ring center and collected by cyclone segregator, the rest of materials are kept by graded ring and processed by centrifugal action, throw forward to the inside wall;then, drop to bottom, smashed and dried again.
Because gas and solid are rotated together, inertia of solid is bigger than gas and the relative velocity between solid and gas is great, this strengthens the process of heating exchange. Therefore, this machine has strong drying capacity.
Applications
Organic compounds
Fenatrol(insecticide of agrochemicals), cadmium laurate, benzoic acid, germicide, sodium oxalate, cellulose acetate.
Dyestuff
Anthraquinone, black ferric oxide, indigo blue pigment, butyric acid titanium hydroxide, zinc sulfuration, all kinds of intermediate of azo dry-stuff.
Inorganic compounds
Borax, calcium carbonate, hydroxide, copper sulphide, ferric oxide, barium carbonate, antimony trioxide, all kinds of metallic hydroxide, kinds of heavy metallic salt, synthetic cryolite.
Foodstuff
Soya protein, agglomerative starch, lees, triticin, wheat starch.
Features
- Raw material is processed by cutting, shearing, blowing, floating and rotating, then become granulated shape and separated greatly, the relative velocity between solid and gas is great, this strengthens the process of heating exchange. Therefore, this machine has strong drying capacity.
- Drying gas enters into the bottom of machine and formed strong rotating airflow, it can wash material sticking on the inside wall, this can remove adhibited material and always keeps inside wall clean.
- In high temperature area at the bottom of equipment, heat sensitive raw material do not need directly contact with heating surface, there is a special device which can solves heat sensitivity material's carbonized and color change problems.
- Gas speed around the drying chamber is high, raw material staying time is short, equipment size is small, large output, high efficiency and quick speed.
- A segmenting ring and a rotational flow piece are equipped in the upper drying room in order to control granulated size and finished products moisture to satisfy required water containing rate and granulation.

Frequently Asked Questions
How does the Spin Flash Dryer handle heat-sensitive materials?
At the bottom of the equipment (the high-temperature zone), a specialized cooling device prevents heat-sensitive raw materials from directly contacting the hot surface. This effectively eliminates problems related to carbonization and discoloration.
What types of materials can be processed by this drying equipment?
It is highly versatile and suitable for organic compounds (like Fenatrol and cellulose acetate), dyestuffs (such as indigo blue pigment and black ferric oxide), inorganic compounds (like calcium carbonate and copper sulphide), and various foodstuff products (including soya protein and wheat starch).
Why does this machine have a high drying efficiency?
The high efficiency is driven by the rotation of gas and solid phases together. Since the solid's inertia is greater than the gas, the relative velocity between them is high, which significantly strengthens the heat exchange process.
How is the moisture content and particle size of the final product controlled?
A segmenting ring and a rotational flow piece are installed in the upper drying chamber. These allow precise control over the granulated size and moisture level of the finished product to meet specific requirements.
Does the material stick to the inside wall during the drying process?
No. The drying gas enters the bottom of the machine and creates a strong rotating airflow. This vortex continuously washes the inside walls, removing any adhibited material and keeping the chamber clean.
How do I choose the correct model for my production needs?
Model selection depends on your required treatment wind capacity and water evaporation rate. For example, the smaller XSG-4 model evaporates 25–70 kg/h of water, while the large-scale XSG-22 model can handle evaporation rates up to 4000 kg/h. Refer to the Technical Parameters table to match your capacity requirements.
