A Tray Dryer is one of the most widely used drying equipment in laboratories, pharmaceuticals, food processing, chemical industries, and research centers. It is designed to remove moisture from products using hot air circulation, ensuring uniform drying, better product stability, and extended shelf life.
Whether you are drying powders, granules, chemicals, food ingredients, or medicinal extracts, a Tray Dryer offers efficient, controlled, and hygienic drying.
What is a Tray Dryer?
A Tray Dryer is a drying chamber equipped with multiple trays where materials are placed for drying. Hot air is circulated inside the chamber either via natural convection or forced air, ensuring uniform heat distribution across all trays.
It is commonly used for batch drying, making it ideal for small to medium-scale production.
How Does a Tray Dryer Work?
The working principle is based on heat transfer and moisture evaporation.
Step-by-Step Working:
- Load the trays with material (powder, granules, food items, chemicals).
- Set the temperature on the digital controller.
- Heaters generate warm air inside the chamber.
- A blower fan circulates the air uniformly.
- Moisture evaporates and is removed via exhaust vents.
- After the cycle is complete, the dried material is unloaded.
This system ensures consistent drying without product contamination.
