© 2023 Google LLC Welcome to our comprehensive guide on mastering tray dryers! In this in-depth video, we unravel the inner workings of tray dryers, covering everything from t. The principle of a tray dryer is based on the process of convection drying. Convection drying involves the use of hot air to remove moisture from the material being dried. The hot air is circulated throughout the drying chamber, and as it passes over the trays, it removes moisture from the materials on the trays. 1. Low Shear mixers/granulators, 2. High Shear mixers/granulators, 3. Fluid-Bed granulators/Tray dryers, 4. Spray Dryers, or 5. Extruders and Spheronizers.

A tray dryer is a convectional drying equipment with enclosed insulated chambers and trays placed on top of each other in a trolley. The driers are used in processes where drying and heating are a crucial part of the industrial manufacturing process such as in the food products, pharmaceutical, dye stuff, and chemicals manufacturing among others. Tray drying is a batch process used to dry materials that are liquid or wet cake. Tray drying works well for material that requires more gentle processing or cannot be atomized in an airstream due to viscosity. This dryer is well utilized for drying wet products like crude drugs, chemicals, powders or the granules, etc.
