Flash drying machine is a new type of rotary drying equipment that integrates drying, crushing, and screening. Suitable for air drying raw materials like filter cake, sticky paste, and rotten mud.

　　The flash dryer quickly dries by using heated gas to pneumatically transport the feed to the flash tube and enter the main air separation device, commonly known as a cyclone. Air is induced or forced into the feed area through a hot gas generator, where it entrains the feed and flashes away moisture during transportation. Send the product into the throat of the feed area of the flash dryer in a controlled manner. The speed of particles is about 80% of the conveying speed, and fine products require secondary dust collection, such as multi-layer, bag houses, scrubbers, and electrostatic precipitators.

The clever design of the flash dryer makes it more efficient and convenient for users to use

1. The flash drying machine adopts multiple devices, such as using multiple feeding devices to ensure continuous and stable feeding, and there will be no bridging phenomenon during the feeding process;

2. A special cooling device is used at the bottom to prevent the material from sticking to the wall and deteriorating in the high-temperature zone at the bottom;

3. Adopting a special air distribution device reduces equipment resistance and effectively provides the processing air volume of the dryer;

4. Adopting special air pressure sealing devices and bearing cooling devices, effectively extending the service life of the transmission part;

5. Adopting a stirring and crushing device to produce strong shearing, blowing, and rotating effects on the material;

6. The drying chamber is equipped with a grading ring and a swirl plate, which can adjust the fineness and final moisture content of the material;

7. Use air filters, cyclone separators, bag filters, etc. to effectively remove dust and avoid environmental and material pollution.

8. An inverted conical structure is installed at the bottom to gradually expand the flow cross-section of dry gas from bottom to top. The bottom airflow is relatively large, while the upper airflow is relatively small, ensuring that the large particles in the lower part are in a fluidized state, while the small particles in the upper part are also in a fluidized state. The hot air is rotated along the vertebral body to increase the bottom wind speed, reduce the length of the cantilever part of the mixing shaft, and increase the safety and reliability of operation;

　　This equipment has strong mass and heat transfer, high production intensity, short drying time, and short material residence time.
