MICROWAVE FLUIDIZED BED DRYER.

The fluidized bed drying technique has been successfully utilized for dehydration of granular and chopped products. Numerous applications include those in the food and pharmaceutical industries. For many materials, however, the drying rate decreases substantially in the final stage of the conventional hot air dehydration process. The drying rate can be considerably increased by the addition of microwave power. This paper presents the results of the investigations of a batch fluidized bed dryer adapted to microwave power processing.
