BIOETP - Model QY-SG-Series -Continuous Sludge Dryer

• Double disc design, large heating area, high energy efficiency. 
• Slight vacuum condition to effect evaporation below 95 ? 
• Special mechanical design for hiding all welding seams, to ensure long service time 
• Optional heating jacket for extra heating area 
• Condensate recover design for more than 20% energy saving

• QY-SG series dryer is perfect for industrial and sewage wastewater sludge drying, also suitable for fish meal, starch, vinasse and other feeds or foods drying.

The complete sludge drying system contains screw conveyor, disc dryer, de-duster, vapor condenser and washing scrubber. Wet sludge from screw press sludge dehydrator usually contains 70-80% moisture. sludge is continuously fed by the screw conveyor to the disc dryer where it will be heated. The moisture in the material vaporizes and drawn by air blower. The waste gas from the dryer will be de-dusted before entering vapor condenser. The condenser turns most vapor into condensate. The vent gas will be washed in a chemical washing scrubber before discharged through chimney. The dry sludge usually containers 20-30% moisture.
