Description:
The Disc Continuous Dryer is a state-of-the-art, efficient, and conductive drying equipment. Its unique structure and operational principle ensure high thermal efficiency, low energy consumption, a compact footprint, simple configuration, ease of operation and control, and an excellent working environment.
Operational Principle:
Wet materials are continuously fed from the feeder to the first layer drying plate at the top of the dryer. The rake arm with rake blades rotates, constantly flipping the materials. These materials traverse the drying tray surface along an exponential spiral. On the small drying tray, materials are transferred to the outer edge and fall onto the large drying tray below. Here, the materials move inward and fall through the middle feeding port to the small drying tray on the next layer. This alternating arrangement ensures a seamless flow through the entire dryer.
The hollow drying plate is filled 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 fall from the last drying tray to the aggregate tray and are finally transported by the rake blades to the discharge port. Moisture overflows and is discharged through the dehumidification port on the top cover. In vacuum disc dryers, moisture is extracted via the vacuum port. The dry materials discharged from the bottom layer can be directly packaged. Auxiliary equipment like finned heaters, solvent recovery condensers, bag filters, pre dryers, and induced draft fans can enhance drying capacity. This system also efficiently handles paste-like and heat-sensitive materials, recovering solvents and performing heating, cooling, calcination, sublimation, pyrolysis, and reaction operations.

Features:
Easy to Regulate
By adjusting the thickness of the material layer, spindle speed, number of rake arms, and the type and size of rake blades, the drying process can be finely tuned for optimal performance.
Each layer of the drying tray can be independently fed with cold or hot media to heat or cool materials, ensuring precise and effortless control of material temperature.
Accurately adjust the residence time of materials, ensuring uniform drying.
Materials flow in a single direction without backmixing, achieving even drying without the need for additional mixing.
Effortless Operation
The operation of starting and stopping the dryer is remarkably straightforward.
When feeding is halted, the material scraper ensures a swift and thorough emptying of the dryer.
Our unique, large inspection door and mirror provide excellent visibility and ease of cleaning for the interior equipment.
Minimal Energy Consumption
Featuring a thin material layer, low spindle speed, and a low-power material conveying system, our dryer is designed to be energy-efficient and cost-effective.
Heat conduction drying delivers outstanding thermal efficiency while keeping energy consumption low.
Environmentally Friendly
Atmospheric Pressure Type: The low airflow velocity and controlled humidity maintain a dust-free environment within the equipment, ensuring that the exhaust gas emitted from the top dehumidification outlet is virtually dust-free.
Sealed Type: Equipped with an efficient solvent recovery device, it ensures the safe recovery of organic solvents from moisture-laden gases. For handling flammable, explosive, toxic, or oxidizable materials, a protective gas can be used for safe, closed-loop drying operations, making it ideal for hazardous materials.
Vacuum Type: This vacuum-operated disc dryer is perfect for safely drying thermosensitive materials.
Simplified Installation
Manufactured and transported as a single unit, our dryer requires only lifting and positioning for seamless installation.
Thanks to its dry tray layout and vertical installation, even a large drying area occupies minimal floor space.
