Description:
The disc continuous dryer is a highly efficient, conductive drying solution. Its unique structure and working principle ensure high thermal efficiency, low energy consumption, compact design, straightforward configuration, ease of operation and control, and an excellent working environment.
Operational Principle:
Wet materials are fed continuously from the feeder to the top drying plate. The rotating rake arm with blades continuously flips the materials, which flow along an exponential spiral across the drying tray surface. The material on the small tray moves to the edge and falls onto the larger tray below, moving inward on the large tray before falling again. This alternating arrangement allows for continuous material flow throughout the dryer.
The hollow drying plates are heated with various media such as saturated steam, hot water, thermal oil, and high-temperature molten salt. The heating medium enters from one end and exits from the other. Dried material is collected on the aggregate tray and discharged by rake blades. Moisture is expelled through dehumidification ports, or in the case of vacuum dryers, extracted via a vacuum port. Directly packaged dry materials can benefit from auxiliary equipment like finned heaters, solvent recovery condensers, bag filters, pre-dryers, and induced draft fans to enhance drying capacity and efficiency. These systems also support drying paste-like and heat-sensitive materials, solvent recovery, and operations such as heating, cooling, calcination, sublimation, pyrolysis, and reactions.

Features:
Ease of Regulation
Optimize the drying process by adjusting material layer thickness, spindle speed, rake arm number, and rake blade type and size.
Each drying tray layer can independently use hot and cold media to precisely control material temperature.
Accurate adjustment of material residence time.
Ensures single-direction material flow with no backmixing, offering uniform drying without the need for additional mixing.
Effortless Operation
The driving and parking operation of the dryer is exceptionally straightforward.
Upon halting the feed, the material scraper efficiently evacuates the contents of the dryer.
The uniquely large inspection door mirror facilitates meticulous cleaning and thorough observation of the interior.
Energy-Efficient Performance
With a thin material layer, low spindle speed, and an efficient material conveying system, the dryer requires minimal power and consumes less electricity.
Conductive drying ensures high thermal efficiency, leading to reduced energy consumption.
Environmental Protection
Atmospheric Pressure Type: With a low internal airflow velocity and variable humidity, dust remains suppressed, resulting in exhaust emissions nearly free of particulates.
Sealed Type: Featuring a solvent recovery device, it efficiently recaptures organic solvents from moisture-laden gases. The straightforward design ensures a high recovery rate. For flammable, explosive, toxic, or oxidizable substances, protective gas can serve as the moisture carrier in a closed-loop system, ensuring safety. Ideal for drying hazardous materials.
Vacuum Type: This disc dryer operates under vacuum conditions, making it perfect for drying heat-sensitive materials.
Hassle-Free Installation
Manufactured and transported as a single unit, the dryer requires only lifting and positioning, simplifying the installation process.
The vertical layout of dry trays ensures a large drying area with a minimal footprint.
