The TPHD Vacuum Paddle Dryer consists of two intermeshing paddle shafts, a W-shaped jacketed shell, base frame, and transmission system. The entire sludge drying process operates under fully enclosed conditions, with organic volatile gases and odorous emissions conveyed to exhaust treatment equipment within the sealed system, effectively preventing environmental pollution. This advanced paddle dryer is specifically designed for indirect heating/cooling of paste-like, granular, powdery, and slurry materials. The TPHD Vacuum Paddle Dryer can perform multiple unit operations including drying, cooling, heating, sterilization, and chemical reactions. Its unique wedge-shaped heat-transfer paddles provide superior thermal efficiency and self-cleaning functionality on heat exchange surfaces.
Function of Hollow Flight Dryer: The Sludge Dryer can dry sludge with over 80% moisture into 10%-30% moisture sludge.
Range of Application: Petrochemical, environmental protection, foodstuff, dyestuff, chemical and other industries.

Flow Chart
Drying Principle:
Heat Transfer
Hot medium (steam/thermal oil) circulates through hollow paddles, indirectly heating the material via metal walls.
Mixing & Conveying
Rotating paddles continuously stir, compress, and advance the material, ensuring full contact with heated surfaces.
Moisture Evaporation
Material moisture evaporates under heat, with vapor removed via exhaust system. Dried product discharges at the outlet.
Heating Medium of hollow blade dryer: Steam or Thermal oil
Available Material Forms: Powder, granules, filter cake and seriflux materials.
Advantages of Paddle Dryer:
1. Low Energy Consumption of Paddle Dryers Paddle dryers operate with indirect heating, eliminating heat loss from large volumes of carry-over air. Combined with insulated outer walls. They achieve exceptional efficiency: only 1.2kg of steam per 1kg of water evaporated for slurry materials. 2. Cost-Effective Paddle Dryer Systems The high heat-transfer surface area per unit volume reduces processing time, enabling smaller equipment sizes and reducing floor space. 3. Broad Material Compatibility of Paddle Dryers By using different heat media (steam, thermal oil, hot/cooling water),paddledryers handle both heat-sensitive materials and high-temperature processes. Suitable for continuous or batch operations across industries. 4. Eco-Friendly Paddle Dryer Design Minimal dust carry-over and solvent emissions due to closed-system operation, simplifying exhaust treatment and reducing environmental impact. 5. Low Operating Costs of Paddle Dryers Robust construction with minimal wear parts ensures low maintenance and long service life. 6. Stable Performance of Paddle Dryers The unique wedge-shaped paddles create a compression-expansion mixing action, ensuring uniform contact between materials and heat surfaces. This maintains consistent temperature, humidity, and mixing gradients for reliable process control. 7. Self-Cleaning Wedge Paddles The self-scouring effect of the paddles enhances heat conduction efficiency and prevents material buildup.
