Tray dryers consist of several trays, which contain the materials to be dried, stacked inside the drying chamber. Air is used as a heat transfer medium that is forced to move inside the chamber. Blowers facilitate air movement. The air gains thermal energy when it contacts the heating coils. The heated air is blown on top of the material, causing the moisture to diffuse and vaporize. A portion of the moisture-carrying air leaves through the ventilation duct, while the rest is recirculated in the chamber together with a stream of fresh, dry air. The temperature and velocity of the air may be adjusted depending on a given product and operational requirements.<\/p>\n
Tray dryers are the simplest type of industrial dryers; they have inexpensive initial costs and consume less space. They are easy to operate and maintain. However, the drying time is typically long. They may not be suitable for powdered solids.<\/p>\n","protected":false},"excerpt":{"rendered":"
