Product Description
Continuous Vacuum Blade Hollow Paddle Dryer
Advanced industrial drying system featuring dual heating surfaces and self-cleaning wedge-shaped blades for efficient sludge dewatering and material processing.
Product Structure & Design
The dryer features a W-shaped shell with jacket construction, housing a pair of hollow low-speed rotating shafts. Multiple mixing blades are welded onto these shafts, with both the jacket and hollow mixing blades equipped to carry thermal media. This dual heating surface design ensures comprehensive material heating throughout the drying process.

Working Principle
The system operates with hot steam circulating through the jacket, hollow shafts, and blades to provide drying heat. A minimal air flow serves as carrier for evaporated steam. Material enters through the feed port and is conveyed by hollow blades to discharge, undergoing continuous heating and evaporation throughout the process.
Key Features
- Compact design with large heat transfer area and minimal footprint
- Uniform stirring with high heat efficiency and superior drying performance
- Self-cleaning blade system prevents material buildup on surfaces
- Low energy consumption and operating costs
- Minimal dust emission and material loss
- Indirect heating prevents material contamination
- Low rotational speed preserves product integrity and properties
- Flexible operation with stable and reliable performance
