摘要： Systems for drying moisture entrained particulate material include a pressurizable chamber for receiving the material to be dried, and a fluid bed device disposed within the chamber for moving the material from an inlet through the chamber to an outlet. A heat exchanger heats the material to be dried flowing into the chamber. Compressing apparatus in the form of a blower pump draws air from the chamber to remove moisture from the material and for compressing the moisture entrained air for heating it. The heated moisture entrained air is guided from the compressing device to the heat exchanger for supplying heat to it. In one form of the invention, a second heat exchanger disposed near the oulet of the chamber cools the material prior to its leaving the chamber for retaining heat within the system. The air flowing from the second heat exchanger is heated by conduction from the blower pump prior to entering the pressurizable chamber for an even more efficient operation of the system.
