| 摘要 |
The invention provides both a method and apparatus for drying moisture-containing materials, in which the material is dried in a drying chamber. A heat exchanger is provided in the drying chamber, and while air is prevented from entering the chamber, vapor or gas given off by the material is extracted from the chamber, at least some of that vapor or gas is compressed, and the compressed vapor or gas is passed through the heat exchanger, so that at least part of the latent heat of evaporation of the vapor or gas at the increased pressure is used to create the necessary temperature gradient between the heat exchanger and the atmosphere within the drying chamber, to cause the heat emission required for drying the material.
