Abstract

The product is placed in a vacuum chamber in which the pressure is reduced by a vacuum pump until water vapor leaves the product. It is then cooled by direct evaporation cooling and absorbed in a zeolite bed before the vacuum pump. Evacuation of the vacuum chamber is matched to the absorption characteristics of the zeolite bed so that the product achieves the desired state e.g. temperature, water content etc. No water vapor flows through the zeolite to the vacuum pump.
