Description:
The disc continuous dryer is an advanced conductive continuous drying system known for its unparalleled efficiency. Its unique structure and operational principles ensure high thermal efficiency, reduced energy consumption, minimal footprint, straightforward configuration, ease of operation and control, and an excellent working environment.
Operational Principle:
Wet materials are continuously fed onto the initial drying plate at the top of the dryer, where a rotating rake arm with blades continuously flips the materials. The material moves across the drying tray surface in an exponential spiral pattern. On smaller trays, materials transfer to the outer edge, falling onto larger trays below, where they move inward and then fall onto the next layer of smaller trays through central feeding ports. This alternating arrangement ensures a continuous material flow through the dryer.
The hollow drying plates are filled with heating mediums such as saturated steam, hot water, thermal oil, or high-temperature molten salt, entering from one end and exiting from the other. Dried materials fall from the final drying tray layer to an aggregate tray and are then transported to the discharge port. Moisture is expelled through a dehumidification port on the top cover or vacuum port for vacuum disc dryers. The processed dry materials can be directly packaged, and auxiliary equipment like finned heaters, solvent recovery condensers, bag filters, pre-dryers, and induced draft fans can enhance production capacity, making it suitable for drying heat-sensitive and paste-like materials, recovering solvents, and performing heating, cooling, calcination, sublimation, pyrolysis, and reaction operations.

Features:
Easy to Regulate
Optimize the drying process by adjusting material layer thickness, spindle speed, rake arm count, and blade type and size.
Each drying tray layer can independently receive hot or cold media for precise material temperature control.
Precisely adjust the material residence time.
Ensures a single flow direction for materials, avoiding backmixing and achieving uniform drying without the need for mixing.
Effortless Operation
The driving and parking operation of the dryer is extremely user-friendly, ensuring smooth and hassle-free usage.
After halting the material feed, the built-in material scraper swiftly clears the dryer, ensuring no residue remains.
The specially designed, large-sized inspection door and mirror allow meticulous cleaning and thorough observation of the internal equipment.
Minimal Energy Consumption
Featuring a thin material layer, slow spindle speed, and a low-power material conveying system, this dryer consumes significantly less electricity.
Drying through heat conduction ensures high thermal efficiency while maintaining low energy consumption.
Environmental Protection
Atmospheric Pressure Type: With low internal airflow velocity and varying humidity, dust is prevented from floating to the top, ensuring that exhaust gas from the dehumidification outlet is virtually dust-free.
Sealed Type: Equipped with a high-efficiency solvent recovery device, it facilitates the convenient recovery of organic solvents from moisture-laden gases. The system is simple yet boasts a high recovery rate. For materials that are flammable, explosive, toxic, or oxidizable, protective gas can be utilized for closed-loop circulation, ensuring safe operations. Ideal for drying sensitive and hazardous materials.
Vacuum Type: Operates under vacuum conditions, making it perfect for the drying of thermosensitive materials.
Simple Installation
Transported as a whole unit, the dryer only requires lifting and positioning, making installation and setup remarkably straightforward.
Thanks to the vertical installation and dry tray layout, the dryer occupies a minimal footprint, regardless of the drying area's size.
