Experts analyze that the Chinese rotary flash dryer market will usher in a new trend

The new equipment for rotary flash drying adopts multiple devices, such as multiple feeding devices, to ensure continuous and stable feeding without bridging during the feeding process; The bottom of the dryer adopts a special cooling device to avoid material sticking and deterioration in the high-temperature zone at the bottom; By using special pneumatic sealing devices and bearing cooling devices, the service life of the transmission part is effectively extended; By using a special air distribution device, the equipment resistance is reduced and the processing air volume of the dryer is effectively provided; The drying chamber is equipped with grading rings and swirl blades, which can adjust the material fineness and final moisture content; Using a stirring and crushing device to generate strong shearing, blowing, and rotating effects on the material; Air filters, cyclone separators, bag filters, etc. are used to effectively remove dust and avoid environmental and material pollution. This equipment has strong mass and heat transfer, high production intensity, short drying time, and short material retention time. This device is widely used for drying food materials such as soy protein, gelatinous starch, and wheat starch.

Experts say that in recent years, the status of rotary flash evaporation dryers in the machinery industry has gradually risen, driving the economic development of the machinery industry and comprehensively promoting the use of flash evaporation dryers.

The rotary flash dryer is a new type of drying equipment newly launched abroad in the 1980s, which integrates drying technology and fluidization technology. It overcomes the shortcomings of high spray drying equipment, high energy consumption and uneven drying of fluidized bed, and combines the advantages of both. Becoming an ideal drying equipment with features such as energy efficiency and speed. It is particularly suitable for the direct drying of high viscosity paste, filter cake and other materials, and can obtain fine particles at one time, which makes up for the shortcomings of low efficiency and small output of rake drying, and changes the complex process of spray drying, dilution first and then spray treatment. Due to the short contact time between hot air and materials, it can dry thixotropic, thermosensitive materials and biological bacteria, and has the effect of preventing coking and discoloration.

In recent years, rotary flash drying has been widely used in the drying of high viscosity, high consistency, and heat sensitive pastes in chemical industries such as light industry, petroleum, chemical fiber, food, mining, coatings, dyes, and intermediates. Compared with other drying equipment, flash dryer technology, compact equipment, simple operation, and convenient maintenance enhance the gas-solid heat transfer effect, greatly shorten the drying time, greatly improve product yield and quality, and have significant energy-saving effects. The equipment occupies a small area, saving both energy and investment. Therefore, this type of equipment immediately attracted the attention of major chemical industry companies around the world after its appearance, and they have introduced it for drying various materials. About seventeen countries in the world have introduced this type of equipment now.

Further promote the opening up of flash dryers to the outside world, learn and draw on the management experience and technology of flash dryers from abroad, and enhance the development and competitiveness of flash dryers in China under the conditions of expanding opening up; Strengthen the supervision of flash evaporation dryers in accordance with the law, and promote the safe and stable operation of flash evaporation dryers.

Experts also suggest that with the widespread application of drying machines, the drying industry will reach a new height, and drying machine manufacturers should not forget to keep up with the pace!
