A tray dryer is a batch-based industrial equipment consisting of an insulated chamber with stacks of trays where wet solid materials are placed. Hot air is circulated through the chamber by fans, which absorbs moisture from the materials, causing it to evaporate and be expelled. These dryers are used in the chemical, pharmaceutical, and food industries to dry various products like powders, granules, and pastes.  How a Tray Dryer Works

1. Loading: Wet materials are spread onto trays, which are then loaded onto a trolley. 
2. Heating: The trolley is rolled into an insulated chamber, and a heating system (electric, steam, or thermic fluid) heats fresh air. 
3. Circulation: A blower fan circulates this heated air over and through the trays, absorbing moisture from the material. 
4. Evaporation: The moisture-laden air is expelled, while new hot air continues the drying cycle until the desired dryness is achieved. 

Key Components

• Trays: Stainless steel trays holding the wet material. 
• Chamber: An insulated cabinet that contains the trays and heating system. 
• Trolley: Used to transport and hold the trays for loading and unloading. 
• Blower/Fans: Circulate the hot air within the chamber to ensure uniform drying. 
• Heating System: Can use steam, electricity, or thermic fluid to generate hot air. 
• Control Panel: Allows for automatic control of temperature and other parameters. 

UsesTray dryers are versatile and used for drying: 

• Pharmaceuticals (powders, granules)
• Chemicals
• Food products
• Dyes and pigments
• Sticky and granulated products
