6600T/A Continuous Plate Dryer Machine SUS304 SUS316L For Solvent Recovery

ISO9001 Good Quality Continual Plate Dryer For Solvent Recovery

The working principle is based on a combination of vertical multi-layer disc conductive heating and mechanical raking. The main unit consists of a closed vertical cylinder containing multiple horizontal hollow heating discs stacked inside, through which steam, hot water, or thermal oil can be circulated. Wet material is continuously fed into the top inlet and falls onto the uppermost heating disc. Rotating rake arms equipped with rake blades continuously turn and stir the material, ensuring even distribution across the disc surface and full contact with the heated surface. The material is gradually pushed by the rake blades toward discharge holes at the outer or inner edge of each disc layer, then falls by gravity onto the next lower disc. This process repeats as the material moves downward, allowing moisture to evaporate progressively. The dried product is discharged from the bottom outlet. Moisture-laden vapor is extracted via exhaust ports at the top and can be connected to dust collection and condensation recovery systems.

Key advantages:

High thermal efficiency: Conductive heating eliminates heat loss due to convective air, achieving an efficiency of over 85%, significantly saving energy.  
Flexible and controllable operation: Residence time of the material inside the machine can be adjusted by varying rotation speed and material layer thickness, accommodating different initial moisture content and final moisture requirements.  
Consistent product quality: Uniform heating and consistent temperature distribution across the discs prevent localized overheating, making it suitable for heat-sensitive materials.  
Closed and environmentally friendly: Fully enclosed operation prevents dust leakage and enables solvent recovery, meeting GMP and environmental standards.  

In addition, the equipment features a compact footprint and high degree of continuous automation. As a result, the disc dryer has become the preferred drying solution in industries such as fine chemicals, battery materials, and food additives.
