Pallet dryers are commonly used indirect dryers for drying or cooling sludge or crystalline & granular materials through gentle heat transfer. They are versatile dryers suitable for various types and characteristics of materials.
The pallet dryer consists of a horizontal body with double shafts and hollow-mounted paddles. The pallets are specially designed to be self-cleaning. Steam or hot oil passes through the dryer body and paddles to heat all internal surfaces.
Moist product is fed into one end of the dryer and moves toward the other end, coming into contact with the heated surfaces of the pallets and drum for drying. The dried product is discharged from the bottom of the paddle dryer. For heat-sensitive products or products with high organic content, the pallet dryer can operate under vacuum.
Advantages:- Low operational cost with high efficiency
- Suitable for sludge and crystalline materials
- Initial particle size is preserved
- Compact design requires less space
- Choice of energy source: steam, hot water, or hot oil
- Environmentally friendly with minimal waste air
- Low maintenance costs
