XPG Series Horizontal Vacuum Paddle Dryer Equipment for Solvent Recovery Toxic Material Drying
The XPG series vacuum paddle dryer is a horizontal batch vacuum drying equipment with solvent condensation recovery and dust removal systems, specifically engineered for processing easily oxidized, explosive, strongly irritating, and highly toxic materials in closed operation.
This advanced dryer features dual heat sources: the vessel jacket and hollow paddles. Unlike traditional rake teeth designs, it utilizes hollow paddle agitation for superior performance. Wet material is fed from the upper feed port, and the main shaft drives the hollow paddles in forward and reverse rotation, continuously renewing the material heating surface.
The complete system efficiently dries paste, pasty, filter cake, and slurry materials under high vacuum and low temperature conditions, with optional solvent recovery. The horizontal structure provides exceptional adaptability for high-viscosity paste and sludge materials, and can be configured with dust removal and solvent condensation recovery systems for applications in fine chemical, pharmaceutical, dye, environmental sludge, and food industries.
- Hazardous materials: Easily oxidized, explosive, strongly irritating and highly toxic materials requiring closed processing
- Solvent recovery materials: Materials requiring solvent condensation recovery during drying
- Heat-sensitive materials: Slurry, paste, powder and pasty materials requiring low-temperature drying

General parameters: Heating source: thermal oil / hot water / low pressure steam | Operation mode: batch production | Jacket design pressure: 0.3 MPa | Pressure in tank: -0.09 ~ 0.15 MPa.
Wet material is fed into the horizontal cylindrical chamber from the upper feed port. Thermal oil, hot water, or low pressure steam is supplied into both the vessel jacket and the hollow agitation paddles, achieving internal and external dual heating.
The main shaft drives the hollow paddles in forward-reverse alternating rotation, continuously pushing, scraping and turning the material while scraping down material sticking to the vessel wall and constantly renewing the heating surface. High vacuum is maintained in the vessel so solvent vaporizes at low temperature.
The vapor passes through the filter for dust removal, is extracted by the vacuum unit, and enters the condenser for solvent recovery. After drying is completed, the bottom discharge valve is opened to discharge the dry material, completing the batch production cycle.
- Configurable auxiliary system: Dust removal device and solvent condensation recovery system available for closed-loop production
- Fully enclosed batch operation: Suitable for easily oxidized, explosive, strongly irritating and highly toxic materials
- High vacuum low temperature drying: Solvent vaporizes at low temperature, ideal for heat-sensitive materials requiring low-temperature processing
- Dual heat source structure: Vessel jacket and hollow paddle agitator supply heat simultaneously, achieving internal and external dual heating with greatly increased effective heating area
- Hollow paddle agitation: Different from traditional rake teeth, the hollow paddle design improves heat transfer efficiency and mixing performance
- Forward-reverse alternating rotation: Continuously pushes, scrapes and turns the material, scraping down wall-sticking material and constantly renewing the heating surface
- Horizontal structure: Strong adaptability for high-viscosity paste, slurry and sludge materials that are difficult for vertical dryers to handle
