    “DryPack” is a calculation tool that visualises the energy consumption of airbased and superheated steam drying processes. With “DryPack”, it is possible to add different components to a simple drying process, and thereby increase the flexibility, which makes it possible to analyse the most common drying processes. Moreover, it is possible to change the configuration of the dryer by including/changing energy saving components to illustrate the potential of the new configuration. The calculation tool is demonstrated in four different case studies, where the actual energy consumption and possible energy consumption reductions by using “DryPack” are calculated.
    With the “DryPack” calculation tool, it is possible to calculate four different unit operations with moist air (dehumidification of air, humidification of air, mixing of two air streams, and heating of air). In addition, a Mollier diagram with temperatures above 100°C may be generated.
