A Tray Dryer Oven is a convectional drying system used for drying solid materials like powders, granules, and even larger items such as herbs or food products. It works by circulating hot air over the materials placed in trays inside a chamber. It’s typically used when a batch-type drying process is required.
This type of dryer operates at atmospheric pressure and is commonly used in pharmaceuticals, chemicals, food processing, and cosmetics industries.
Wet materials are spread evenly on trays.
Trays are placed inside the chamber on rack slots.
The door is closed and sealed.
Air is heated using the chosen heating method.
A fan/blower circulates the hot air uniformly across the trays.
Moisture evaporates and is carried away by the airflow.
After the drying cycle, the materials are removed from trays.
