Flash dryer: low energy consumption and high thermal efficiency

The Flash Dryer enters the bottom of the Dryer tangentially from hot air, and is driven by the agitator to form a powerful rotating wind field. The material enters the dryer from 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 quickly crushed, fully contacted with hot air, heated and dried . The dried materials are carried by the airflow into the dust collection system for collection and processing. The exhaust gas with dust content of <50mg/m3 in compliance with environmental protection requirements is evacuated by the induced draft fan to complete the entire drying process.

The advantages of flash dryer equipment

1 The drying chamber has high circumferential air velocity and short material residence time, which can effectively prevent the material from sticking to the wall and the deterioration of heat-sensitive materials, and can be dried into a uniform powder product at one time, eliminating the need for crushing, screening and other processes.

2 The drying chamber is equipped with a grading ring and a swirl plate, and the fineness of the material and the final moisture are adjustable. The special air distribution device reduces the resistance of the equipment and effectively improves the drying uniformity of the material.

3 The bottom of the dryer is equipped with a special cooling device and air pressure sealing device to avoid the deterioration of the material in the high temperature zone at the bottom.

4 can effectively control the final moisture and fineness, through the adjustment of the feeding, hot air temperature, and classifier to ensure that the moisture content and fineness of the product are uniform.
