principle
The wet material entering the fluidized bed comes into contact with the hot air above the air distribution plate, and the material particles are suspended in the airflow, forming fluidization. The tubular heat exchanger is immersed in the fluidized material, and steam is passed through the heat exchange tubes. The heat required for material dehydration is provided by both the tubular heat exchanger and the hot air used for fluidization. The dried finished product is discharged from the discharge port of the fluidized bed, and the dust containing gas is purified by the dust collection device and discharged into the atmosphere by the induced draft fan.

Energy saving and efficient. Due to the fact that most of the heat is provided by the built-in heat exchanger with a heat exchange efficiency of about 90%, the hot air is mainly used as
The power medium that ensures normal fluidization greatly reduces the amount of hot air required compared to conventional fluidized bed dryers. Therefore, its system power consumption and emissions
The gas and heat losses are correspondingly reduced, resulting in high drying efficiency.
Small footprint and low system investment.
Due to the lower operating gas ratio of the internal heating fluidized bed system compared to conventional fluidized beds, it can effectively reduce material entrainment and settling losses in the fluidized bed, thereby reducing the load on the dust removal system and alleviating environmental pressure.
Using special air distribution boards can prevent material leakage.
