Description:
The disc continuous dryer is an advanced and efficient conductive continuous drying equipment. Its unique structure and working principle ensure it offers high thermal efficiency, low energy consumption, minimal footprint, simple configuration, easy operation and control, and a favorable operating environment.
Operational Principle:
Wet materials are continuously fed from the feeder to the first layer drying plate on the upper part of the dryer. The rotating rake arm with rake blades ensures constant flipping of materials. As the material flows along an exponential spiral across the surface of the drying tray, it transitions from smaller to larger trays in an alternating pattern, facilitating continuous movement through the entire dryer.
The hollow drying plates are filled with heating mediums such as saturated steam, hot water, thermal oil, or high-temperature molten salt. These mediums flow through the drying plates, ensuring efficient heat transfer. The dried material is eventually transported to the discharge port by rake blades, while moisture is expelled through the dehumidification port on the top cover. In vacuum disc dryers, moisture is extracted via the vacuum port. The dried material can be directly packaged or further processed with auxiliary equipment like finned heaters, solvent recovery condensers, bag filters, pre-dryers, and induced draft fans.

Features:
Easy to Regulate
Optimize the drying process by adjusting the material layer thickness, spindle speed, number of rake arms, and rake blade types and sizes.
Each drying tray layer can be individually fed with hot or cold media, allowing precise and effortless control of material temperature.
Accurately manage the residence time of materials.
With a unidirectional material flow, our system eliminates backmixing, ensuring uniform drying without the need for additional mixing.
Effortless Operation
The driving and parking operations of the dryer are intuitively user-friendly, ensuring an effortless experience.
Upon halting the feed, the material scraper swiftly evacuates the remaining contents within the dryer, ensuring a quick and efficient clean-out.
A specially designed large-sized inspection door mirror provides meticulous cleaning and thorough observation of the equipment's interior.
Energy-Efficient Functionality
With a thin material layer, slow spindle speed, and a low-power material conveying system, this equipment is designed to minimize electricity consumption.
Drying via heat conduction ensures superior thermal efficiency while maintaining low energy consumption.
Eco-friendly Solution
Atmospheric pressure type: The equipment operates at low airflow velocity, maintaining high humidity levels inside, which hinders dust from rising. Consequently, the exhaust gas emitted from the dehumidification outlet is virtually dust-free.
Sealed type: Featuring a convenient solvent recovery device, it efficiently recovers organic solvents from moisture-laden gases. The device is simple to use with a high recovery rate. For drying flammable, explosive, toxic, and oxidizable materials, protective gas can be utilized for closed-loop circulation, ensuring safe operation. Ideal for drying hazardous materials.
Vacuum type: This vacuum-operated disc dryer is particularly suitable for drying heat-sensitive materials with precision.
Effortless Installation
The dryer is pre-assembled and transported in one piece, requiring only lifting and positioning for installation, simplifying the setup process.
With its dry tray layout and vertical installation, the dryer offers a large drying area while occupying minimal floor space.
