AIR TRAY DRYER (ATD)
Tray dryers are commonly used in various
industries, including pharmaceuticals, chemicals,
food processing, and more, for the drying of solid
materials. Here's an overview of the utilization of
tray dryers and the associated process:

It is important to note that the specific utilization and process of a tray dryer may vary
depending on the manufacturer, model, and the specific requirements of the drying process. However,
the controlled temperature, uniform airflow, and efficient drying capabilities of tray dryers make them
valuable equipment for drying solid materials in various industries.
