Essentially, the calculation of drying energy consumption is based on the drying gas parameters. However, determination of the attainable top-line dryer for indices such as specific energy consumption and energy efficiency, as well as an analysis of options for reducing energy consumption are based on material properties (e.g., specific heat, sorption isotherms). As such properties are not readily available, the tool allows calculation of needed parameters or, at least, the use of properties of the materials most similar to the drying …
