Paddle Dryer
The Paddle dryer is suitable for Drying the sludge at a low temperature as 150- degree Celsius. This machine uses conductive heat with a horizontal mixing mechanism, so continuous operation is possible to maximize production efficiency. The special wedge-type stirring heat transfer blades in the equipment have high heat transfer efficiency. It’s utilized in varied industries to extract dry powder either from solutions as high as 80% to 90% moisture or wet cake.
Features
- Efficient drying of sludge and paste through direct contact.
- Low running and maintenance cost
- Compact construction – less floor area.
- Minimum exhaust air quantity
- Special paddle form – ploughing and self-cleaning action
Working Principle :
- The paddle dryer is compact in structure and mainly consists of a sandwich casing, a central shaft with staggered blades, inlet and outlet joints, drive mechanisms, control boxes, and other components.
- The mechanism, involves a closed system wherein hot water, steam, or hot fluid is used as a heating medium within the jacket, in the hollow paddle as well as in the hallow shaft.
- The temperature range of heating media is 80 ℃ to 250 ℃depending on Heating Source. Heating source could be steam, liquid state, such as steam, thermal oil etc.
- The surface of chock shaped blade has self-cleaning function. The relative movements of the product particles and the chocked shaped blades surface clean the materials attached to the blades surface.
- The shell of hollow blade paddle dryer is Ω shape. To avoid any leakage of materials and dust. After heat transfer and drying, it is discharged out of machine through rotary joint.
