A tray dryer is a convectional drying equipment with enclosed insulated chambers and trays placed on top of each other in a trolley.Tray dryers are well suited to drying sticky materials, granular mass or crystallized materials, precipitates, and pastes. Agricultural drying has been made possible with its simple design and capacity to dry large quantities of products.Tray dryers are great for drying a wide range of materials, from liquids to solids. They can also dry parts of a product, such as a paste. They have large working areas, a temperature controller, and uniform air circulation. Small-scale production operations can benefit from the convenience of a tray dryer.
