Description:
The disc continuous dryer is a highly efficient and conductive drying equipment, distinguished by its unique structure and operational principle. It boasts high thermal efficiency, low energy consumption, a compact footprint, simple configuration, ease of operation and control, and a superior operating 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, persistently flipping the materials. The material flows across the drying tray surface in an exponential spiral. On smaller drying trays, materials are transferred to the outer edge, descending to the larger drying trays below. Here, materials move inward, falling through the central feeding port into the next layer of smaller drying trays, creating a continuous flow through the entire dryer.
The hollow drying plate is infused with heating mediums such as saturated steam, hot water, thermal oil, or high-temperature molten salt. These mediums enter from one end of the drying plate and exit from the other. The dried materials fall from the final drying tray to the aggregate tray and are eventually transported by rake blades to the discharge port. Moisture is released from the materials and expelled through a dehumidification port on the top cover. For vacuum disc dryers, the moisture is extracted via a vacuum port on the top cover. The dry materials discharged from the bottom layer are ready for direct packaging. The production capacity can be enhanced by integrating auxiliary equipment like finned heaters, solvent recovery condensers, bag filters, pre-dryers, and induced draft fans. This setup facilitates easy recovery of solvents and supports a variety of operations including heating, cooling, calcination, sublimation, pyrolysis, and reaction processes.

Features:
Easily Adjustable
Optimize the drying process by adjusting the material layer thickness, spindle speed, number of rake arms, rake blade type, and size.
Each drying tray layer can be individually fed with hot or cold media to accurately and easily control the material temperature.
Precisely control the material residence time.
The material flows in a single direction with no backmixing, ensuring even drying without the need for additional mixing.
Effortless Operation
The operation for both driving and parking the dryer is incredibly straightforward.
Upon halting the feed, the material scraper ensures a swift and thorough emptying of the dryer's interior.
The uniquely designed large inspection door mirror facilitates meticulous cleaning and comprehensive observation of the equipment's interior.
Minimal Energy Consumption
With a very thin material layer, low spindle speed, and a material conveying system that demands minimal power, this dryer is exceptionally energy-efficient.
High thermal efficiency and low energy consumption are achieved through effective heat conduction drying.
Environmentally Friendly
Atmospheric Pressure Type: The low airflow velocity and varying humidity levels inside the equipment prevent dust from floating to the top. As a result, the exhaust gas from the dehumidification outlet is virtually dust-free.
Sealed Type: Equipped with a high-efficiency solvent recovery device, it seamlessly recovers organic solvents from moisture-laden gases. The device is simple yet highly effective, with a high recovery rate. For materials that are flammable, explosive, toxic, or oxidizable, protective gas can be used for closed-loop circulation, ensuring safe operation. This type is ideal for drying hazardous materials.
Vacuum Type: Operated under vacuum conditions, this disc dryer is particularly suitable for drying thermosensitive materials.
Hassle-Free Installation
The dryer comes as a fully assembled unit. Simply lift, position, and it's ready to go, making installation and positioning a breeze.
The vertical layout of the dry trays ensures a large drying area while maintaining a minimal footprint.
