Description:
The disc continuous dryer is a highly efficient conductive drying system, renowned for its unique structure and operating principle. It offers exceptional thermal efficiency, low energy consumption, a compact footprint, straightforward configuration, easy operation and control, and a favorable operating environment.
Operational Principle:
Wet materials are continuously introduced from the feeder onto the first layer drying plate at the top of the dryer. Here, a rotating rake arm with rake blades continuously flips the materials, guiding them along an exponential spiral across the drying tray. Materials transition from small to large drying trays, alternating between layers, ensuring continuous flow through the entire dryer.
The hollow drying plates, filled with heating mediums like saturated steam, hot water, thermal oil, or high-temperature molten salt, heat the materials efficiently. Dried materials fall from the last layer to the aggregate tray and are finally moved by rake blades to the discharge port. Moisture evaporates and exits via the dehumidification port or vacuum port on the top cover. By integrating auxiliary equipment like finned heaters, solvent recovery condensers, bag filters, pre-dryers, and induced draft fans, we enhance drying capacity, solvent recovery, and allow various operations like heating, cooling, calcination, sublimation, pyrolysis, and reaction.

Features:
Easy Regulation
Optimize the drying process by adjusting material layer thickness, spindle speed, number of rake arms, and rake blade type and size.
Each drying tray layer can be individually fed with cold or hot media, facilitating precise material temperature control.
Precisely control the material residence time for optimal drying.
The material flows in a single direction, preventing backmixing and ensuring uniform drying without the need for additional mixing.
Effortless Operation
The operation of driving and parking the dryer is remarkably simple, making it user-friendly and efficient.
Once the feeding process is halted, the material scraper swiftly empties the contents within the dryer, ensuring a clean and ready state for the next operation.
Featuring a special large-sized inspection door mirror, this dryer allows for meticulous cleaning and detailed observation of the internal equipment, enhancing maintenance and operational accuracy.
Remarkably Low Energy Consumption
With a very thin material layer and low spindle speed, the material conveying system demands minimal power, resulting in exceptionally low electricity consumption.
Drying via heat conduction delivers high thermal efficiency coupled with significantly low energy consumption, offering an eco-friendly solution.
Environmentally Conscious Design
Atmospheric Pressure Type: With low airflow velocity and varying humidity levels, dust remains confined within the equipment, ensuring that the exhaust gas from the top dehumidification outlet is nearly dust-free.
Sealed Type: Equipped with an efficient solvent recovery device, it conveniently recovers organic solvents from moisture-carrying gases. This simple, high-recovery system ensures safe operation with flammable, explosive, toxic, and oxidizable materials by using protective gas for closed-loop circulation, making it ideal for such sensitive applications.
Vacuum Type: This disc dryer operates under vacuum conditions, making it perfect for drying thermosensitive materials, preserving their integrity and quality.
Easily Installable
The dryer is designed for straightforward installation; being manufactured and transported as a whole, it merely requires lifting and positioning, simplifying the setup process.
Thanks to its dry tray layout and vertical installation, it boasts a large drying area while minimizing its footprint, making it space-efficient.
