The new type of rotary flash drying equipment 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; The bottom of the dryer adopts a special cooling device, which avoids the phenomenon of material sticking and deterioration in the high-temperature area at the bottom; Adopting special air pressure sealing devices and bearing cooling devices, effectively extending the service life of the transmission part; 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 room is equipped with a grading ring and a swirl plate, which can adjust the fineness and final moisture content of the material; Adopting a stirring and crushing device, it produces strong shearing, blowing, and rotating effects on the material; Using air filters, cyclone separators, bag filters, etc., effectively removes dust and avoids environmental and material pollution. This equipment has strong mass and heat transfer, high production intensity, short drying time, and short material residence time. This equipment is widely used for drying food materials such as soy protein, gelatinous starch, and wheat starch.
Experts say that in recent years, the position of rotary flash drying machines in the mechanical industry has gradually risen, driving the economic development of the mechanical industry and comprehensively promoting the use of flash drying machines.
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 characteristics such as energy efficiency, speed, etc. 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 discoloration.
In recent years, rotary flash drying has been widely used in the drying of high viscosity, high viscosity, 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, the flash drying machine has advanced technology, compact equipment, simple operation, and convenient maintenance, which enhances the gas-solid heat transfer effect, greatly shortens drying time, greatly improves product output and quality, and has significant energy-saving effects. The equipment occupies a small area, saving both energy and investment. Therefore, this device immediately attracted the attention of major chemical industry companies around the world and was introduced for drying various materials. About seventeen countries in the world have introduced this device now.
Further promote the opening up of flash drying machines to the outside world, learn and learn from the management experience and technology of foreign flash drying machines, and enhance the development and competitiveness of flash drying machines in China under the conditions of expanding opening up; Strengthen the supervision of flash drying machines in accordance with the law, and promote the safe and stable operation of flash drying machines.
Experts also say that with the widespread application of dryers at present, it will drive the drying industry to a new height. Don't forget to keep up with dryer manufacturers!
