Description:
The disc continuous dryer is a highly efficient conductive drying system featuring a unique structure and operating principle. This equipment is known for its outstanding thermal efficiency, minimal energy consumption, compact footprint, simple design, ease of operation, and excellent control, resulting in a superior operational environment.
Operational Principle:
Wet materials are continuously fed onto the first layer drying plate at the top of the dryer. As the rake arm with blades rotates, it perpetually flips the materials, which move along an exponential spiral across the drying tray surface. The materials transition from smaller to larger drying plates in an alternating up-and-down arrangement, ensuring consistent flow through the entire dryer.
The hollow drying plates are infused with a heating medium, such as saturated steam, hot water, thermal oil, or high-temperature molten salt, entering from one end and exiting from the other. Dried materials descend from the last drying tray to the aggregate tray and are then transported by rake blades to the discharge port. Moisture is expelled through the top cover's dehumidification port or extracted via the vacuum port. The final dry materials can be directly packaged. Enhancing the drying process with auxiliary equipment like finned heaters, solvent recovery condensers, bag filters, pre-dryers, and induced draft fans boosts production capacity and facilitates the recovery of solvents, along with other operations such as heating, cooling, calcination, sublimation, pyrolysis, and reactions.

Features:
Easy to Regulate
Optimize the drying process by adjusting material layer thickness, spindle speed, number of rake arms, and the type and size of rake blades.
Each drying tray layer can be independently fed with cold or hot media to precisely control material temperature.
Accurately adjust the residence time of materials.
The material follows a streamlined, single-direction flow, eliminating backmixing issues and ensuring uniform drying without the necessity for additional mixing.
Effortless Operation
Operating and halting the dryer is straightforward and user-friendly.
After the feeding process stops, the material scraper swiftly clears out the contents of the dryer.
The specially designed large-sized inspection door mirror allows meticulous cleaning and comprehensive observation of the internal equipment.
Minimal Energy Consumption
Thanks to the thin material layer and low spindle speed, the material conveying system is power-efficient and consumes significantly less electricity.
High thermal efficiency is achieved through heat conduction drying, which also ensures low energy consumption.
Environmental Protection
Atmospheric Pressure Type: The low internal airflow velocity and varied humidity levels hinder dust from floating, ensuring that exhaust gases from the top dehumidification outlet are almost dust-free.
Sealed Type: Equipped with a solvent recovery device, it efficiently recovers organic solvents from moisture-laden gases. The device is simple and boasts a high recovery rate. For flammable, explosive, toxic, and oxidizable materials, protective gas can be used as a moisture carrier for closed-loop circulation, guaranteeing safe operation. Ideal for drying highly sensitive materials.
Vacuum Type: Operating under vacuum conditions, this disc dryer is perfect for drying thermosensitive materials.
Effortless Installation
The dryer is transportable and fully assembled, requiring only lifting and positioning for easy installation.
With the dry tray layout and vertical setup, the dryer offers extensive drying areas while occupying minimal floor space.
