Contact SupplierWe supply Tray Dryer that is adequately designed by our designers and adroit personnel who take every care in the fabrication of a durable and highly efficient range of machines. Available in various models such as 12 trays, 24 trays, 48 trays, 96trays, these are high in performance and low on maintenance. The major problem in calculations on real dryers is that conditions change as the drying air and the drying solids move along the dryer in a continuous dryer, or change with time in the batch dryer. Such implications take them beyond the scope of the present book, but the principles of mass and heat balances are the basis and the analysis is not difficult once the fundamental principles of drying are understood. Obtaining adequate data may be the difficult part. In tray dryers, the food is spread out, generally quite thinly, on trays in which the drying takes place. Heating may be by an air current sweeping across the trays, by conduction from heated trays or heated shelves on which the trays lie, or by radiation from heated surfaces. Most tray dryers are heated by air, which also removes the moist vapours.
