Air Tray Dryer is a widely used batch-type drying equipment designed for uniform and controlled drying of various materials such as powders, granules, chemicals, pharmaceuticals, and food products. It operates using hot air circulation inside an insulated chamber containing multiple trays where materials are placed for efficient moisture removal.
The equipment is known for its energy efficiency, hygienic construction, consistent drying performance, and ease of operation, making it suitable for diverse industrial applications.
Working Principle
Air Tray Dryer works on the principle of hot air convection drying. Heated air is generated using electric heaters, steam coils, or gas burners and circulated through the drying chamber with the help of blowers.
The hot air passes uniformly over the trays containing wet materials, transferring heat and removing moisture through evaporation. Continuous air circulation ensures consistent temperature distribution and uniform drying throughout the process.
