Air separation device and drying time of high speed rotating dryer
Feb 07, 2019

The high speed rotating dryer mainly uses a variety of advanced devices in the process of operation, such as using a variety of feeding devices, so that the feeding can be continuously stabilized, the feeding process does not cause bridging, and the bottom of the dryer is special. The cooling device avoids the phenomenon that the material is stuck and deteriorated in the high temperature zone at the bottom, and the special air pressure sealing device and the bearing cooling device are used to effectively extend the service life of the transmission part.

The high speed rotating dryer adopts a special air separation device, which reduces the resistance of the equipment during use, effectively provides the processing air volume of the dryer, and the drying chamber is equipped with a step ring and a swirling sheet, which can adjust the material fineness and The final moisture; the stirring and pulverizing device is used to produce strong shearing, blowing and rotating effects on the material; the air filter, the cyclone separator and the bag filter are used to effectively remove dust and avoid environmental and material pollution. The device has strong mass transfer heat transfer, high production intensity, short drying time and short material residence time. The device is widely used for drying food materials such as soy protein, gelatinized starch and wheat starch.

The hot air tangential line of the high speed rotating dryer enters the bottom of the dryer and is driven by the agitator to form a powerful rotating wind field. The paste material enters the dryer by the screw feeder. Under the strong action of the high-speed rotating stirring paddle, the material is dispersed under the action of impact, friction and shearing force. The block material is rapidly pulverized, fully contacted with hot air and heated dry.
