Inner heated fluid bed dryer is developed based on normal fluid bed dryer and indirect heated dryer. Immerse the heat exchanger in the material that is fluidized and dried. The heat required for dewatering is provided by tube heat exchanger and fluidizing hot air. The air velocity required for to dry the material is less. The main heat is provided by the heat exchanger inside, the hot air is mainly for fluidization of material, so the hot air velocity required is much less compare to normal fluid bed dryer, power consumption and heat lost with the tail gas are sharply reduced.

Energy saving, low running cost

The amount of drying air is less; the power consumption is low.

The drying capacity is high; the volume of equipment is small; the area occupied is less.

The operation flexibility is high; the operation of system is steady.

Adopt special air distributing board, so to avoid leakage of material, and it's good for discharging material of big particles.

Adopt two grades of dust filter, so to meet exhaust requirements of environment.
