Tray Dryers

Tray Dryers

Tray dryers remove moisture from products placed on trays inside an enclosed drying chamber. Heated air is passed around the trays to carry away evaporated moisture, with the drying rate influenced by air temperature, humidity, airflow, tray loading, product depth, and the material's moisture characteristics. Industrial tray dryers can be configured for batch production and may include multiple trays, adjustable air distribution, exhaust control, insulation, and programmable temperature settings. Uniform drying requires more than adequate heater power: airflow should reach the loaded trays without excessive bypass, and the exhaust should remove moisture-laden air at a suitable rate. The chamber materials and air-handling arrangement should suit the product and hygiene requirements. For heat-sensitive materials, controlled ramping and lower-temperature operation may be more appropriate than maximising temperature.
