Description:
The disc continuous dryer stands out as an efficient conductive continuous drying solution. Its unique design and operational principle ensure high thermal efficiency, low energy consumption, compact size, simplified configuration, user-friendly operation, and a favorable working environment.
Operational Principle:
Wet materials are continuously fed from the top feeder to the first layer drying plate, where a rotating rake arm with blades constantly flips them. As the material flows across the drying tray surface in an exponential spiral, it transitions from the small drying tray to the larger one below. This alternating arrangement of large and small trays allows for a continuous material flow throughout the dryer.
The hollow drying plate is filled with various heating mediums such as saturated steam, hot water, thermal oil, or high-temperature molten salt, entering from one end and exiting from the other. The dried material is collected in an aggregate tray and discharged via the rake blades. Moisture is expelled through dehumidification or vacuum ports, with the possibility of adding auxiliary equipment like finned heaters, solvent recovery condensers, bag filters, pre-dryers, and induced draft fans to enhance drying efficiency for paste-like and heat-sensitive materials, while also facilitating solvent recovery and enabling heating, cooling, calcination, sublimation, pyrolysis, and reaction processes.

Features:
Easy to regulate
The drying process can be precisely optimized by adjusting the material layer thickness, spindle speed, number of rake arms, and the type and size of rake blades.
Each layer of the drying tray can be independently supplied with cold or hot media to accurately control the material temperature.
The residence time of materials can be finely tuned.
Materials flow in a single direction without backmixing, ensuring uniform drying without the need for additional mixing.
Effortless Operation
Operating and parking the dryer is remarkably straightforward, designed for user convenience.
Once feeding stops, the material scraper swiftly clears out the contents of the dryer, ensuring minimal downtime.
The generous, specially-designed inspection door mirror allows meticulous cleaning and thorough observation of the equipment's interior.
Energy-Efficient Performance
With a thin material layer and low spindle speed, the material conveying system is designed to be power-efficient, minimizing electricity consumption.
Drying through heat conduction guarantees high thermal efficiency while keeping energy consumption low.
Environmentally Friendly
Atmospheric Pressure Type: The equipment's low internal airflow velocity and balanced humidity levels prevent dust from suspending, ensuring that exhaust gases are almost dust-free.
Sealed Type: Featuring a solvent recovery device for easy and efficient recovery of organic solvents from moisture-laden gases. This setup boasts a high recovery rate and is ideal for drying flammable, explosive, oxidizable, or toxic materials. The use of protective gas for moisture carrying ensures safe, closed-loop operation.
Vacuum Type: Specifically designed for drying heat-sensitive materials under vacuum conditions, enhancing efficiency and product quality.
Simple Installation
The dryer is transported as a single unit, requiring only lifting and positioning for quick and easy installation.
With a compact vertical installation and dry tray design, the equipment takes up minimal floor space even if the drying area is substantial.
