The flash drying machine utilizes hot air entering at an angle from the bottom of the dryer, creating a powerful rotating air field under the action of the agitator. Materials are introduced into the dryer via a spiral feeder, where they are dispersed under the intense force of the high-speed rotating impeller, experiencing impacts, friction, and shearing forces. This leads to the rapid pulverization of lumpy materials, allowing for thorough contact with the hot air, heat absorption, and drying. The dried materials are then carried by the air flow into the dust collection system for collection and processing. The exhaust gas, which meets environmental protection requirements with a dust content of less than 50mg/m3, is exhausted through an induced draft fan, completing the entire drying process.
Advantages of Flash Dryer Equipment
The drying chamber features high circumferential air velocity, resulting in short material residence time, effectively preventing material adhesion to the walls and the deterioration of heat-sensitive materials. It can also dry materials into a uniform powdered product in one go, eliminating the need for processes such as crushing and sieving.
The drying chamber is equipped with grading rings and swirl plates, allowing for adjustable particle fineness and final moisture content. A special air distribution device reduces equipment resistance and effectively enhances the uniformity of material drying.
The bottom of the dryer is equipped with special cooling devices and pressure-sealed fittings, preventing material from deteriorating in the high-temperature area at the bottom.
The 4 can effectively control the final moisture content and fineness. By adjusting the addition of materials, hot air temperature, and classifier, it ensures uniform and consistent moisture content and fineness of the product.
