Wet material is continuously fed onto the top drying tray via a feeder. Rotating rakes with blades continuously turn and convey the material in an exponential spiral path across the tray surface:
● On small trays, material moves outward and falls to the larger tray below.
● On larger trays, material moves inward and drops through the central discharge to the next small tray.
● Alternating tray sizes ensure continuous material flow.
Heating Media (steam, hot water, thermal oil) circulate through hollow trays, entering at one end and exiting at the other. Dried material discharges from the bottom tray, while moisture escapes through the top vent (or vacuum port for vacuum models).
Optional Accessories (e.g., finned heaters, solvent recovery condensers, bag filters, back-mixing systems, exhaust fans) enhance drying capacity, enable paste/heat-sensitive material processing, and support solvent recovery or pyrolysis/reaction operations.

Product Features
(1) Precise Control & High Adaptability
Adjustable material bed thickness, shaft speed, rake arm/blade configuration for optimal drying.
Individual tray temperature control (heating/cooling) for accurate material treatment.
Precise residence time adjustment.
Unidirectional material flow ensures uniform drying without back-mixing.
(2) Easy Operation & Maintenance
Simple start-up/shutdown.
Fast self-emptying after feed stoppage.
Large inspection doors for cleaning and observation.
(3) Low Energy Consumption
Thin material bed + low shaft speed → minimal power demand.
High thermal efficiency (conduction-based) with low heat loss.
(4) Eco-Friendly & Safe
Atmospheric models: Low internal airflow + humidity gradient → dust-free exhaust.
Closed-loop models: Integrated solvent recovery (compatible with N₂ inerting for flammable/toxic materials).
Vacuum models: Ideal for heat-sensitive materials.
(5) Compact & Easy Installation
Pre-assembled delivery → quick on-site setup.
Vertical stacked-tray design maximizes drying area within a small footprint.
The flow ability is improved and the dust is reduced, because of Granulator.
Because of powder Granulating, its solubility is improved.
The processes of Mixing, Granulating and drying are completed in one step inside the machine.
The operation is safe because the anti-static filter cloth adopted.
It's safe for operator if explosion take place, because explosion device is adopted.
No dead corner. Therefore the loading and unloading are quick, light and clean, meet the requirements of GMP.
