Hollow Paddle Dryer

Hollow Blade Dryer

Hollow Paddle Dryer is a continuous indirect heating device for drying (cooling) materials, such as dried sludge from sewage dewatering machine( take sludge screw press for example)

Working Principle

Hollow Paddle Dryer is a continuous indirect heating device for drying (cooling) materials
There are two parallel rotary shafts inlaid with interlaced paddles in the jacket shell
Each shaft is inlaid with hollow fan-shaped paddles staggered at a certain interval, and the shaft rotates at a low speed
The heat medium enters the hollow rotary shaft and paddle through the rotary joint installed at the end of the rotary shaft
After heat transfer and drying, it is discharged out of the machine through the rotary joint
Heat medium will also be introduced into the jacket
