Rotary dryer, food industry

Continuous conveyor, through-circulation, or impinging jet-fluidized bed dryers (sometimes called jet-zone dryers) are often used in the wood processing (e.g., wafer board) and food processing (e.g., potato chips, etc.) industries. In the jet-zone process, hot air jets impinge on a thin layer of wet chips, which are conveyed mechanically the high-velocity jets pseudo-fluidize the material to accomplish uniform drying. Wood chips, for example, may be dried in a rotary or a conveyor dryer.
